¶1 Eric Patrick Regan was arrested for driving with a suspended license. In a search incident to arrest, police found methamphetamine, marijuana, and drug paraphernalia in the car, which belonged to Mr. Regan’s girl friend. Mr. Regan was convicted of possession of the drugs, use of paraphernalia, and bail jumping. On *423appeal, Mr. Regan challenges the court’s order that his defense counsel testify against him to prove that he knowingly failed to appear for trial. We conclude that due to defense counsel’s involvement as both a witness and attorney, Mr. Regan was adversely affected by his counsel’s actual conflict of interest. We therefore reverse his convictions.
Schultheis, J.*423Facts
¶2 While stopped for a red light in downtown Moses Lake at 1:30 a.m. on September 20, 2005, city police officer Greg Nevarez recognized a driver, Eric Regan, whose license Officer Nevarez believed to be suspended. After confirming the suspension with dispatch, Officer Nevarez stopped Mr. Regan in a hospital parking lot. Officer Nevarez approached Mr. Regan and informed him that he was under arrest for driving with a suspended license.
¶3 Sergeant Brian Jones arrived and assisted in the search of the car incident to arrest. Beneath clothes and newspapers on the front passenger seat, he found a camera case that contained methamphetamine, marijuana, a marijuana pipe, and a methamphetamine pipe.
¶4 On March 8, 2006, Mr. Regan proceeded to trial on charges of possession of a controlled substance other than marijuana (methamphetamine), possession of 40 grams or less of marijuana, and use of drug paraphernalia.1 Attorneys Elizabeth Vasiliades and Alan White appeared for Mr. Regan.2 Ms. Vasiliades acted as primary counsel and, *424because it was only her second felony trial, Mr. White assisted as her supervising attorney.
¶5 Mr. Regan arrived for his trial more than one hour late. Very shortly before that, after a very long wait, the trial court had released the jury and issued a bench warrant for his arrest for failure to appear. The information was amended to charge Mr. Regan with bail jumping. He was detained pending trial to ensure his attendance.
¶6 On April 18, the court heard Mr. Regan’s motion to quash a subpoena. The State wanted Mr. White to testify against Mr. Regan concerning the bail jumping charge to show that defense counsel told Mr. Regan to arrive early for court on March 8. The court held that it was not “unduly oppressive” to compel Mr. White to testify under the circumstances because Mr. White had made arrangements for another attorney to supervise Ms. Vasiliades if the trial date fell on Mr. White’s vacation, so it was not necessary for Mr. White to personally supervise Ms. Vasiliades. Report of Proceedings (RP) (Apr. 18, 2006) at 9. The court continued Mr. Regan’s trial, which was scheduled to start the next day, to accommodate Mr. White’s vacation as well as the prosecutor’s vacation.
¶7 When trial commenced on May 3, Mr. White again objected to having to act as a witness against his client. The judge held that he was aware of no authority that prohibited compulsion of the testimony. Concerned it might be error to have Mr. White seated at the counsel table, however, he directed Mr. White not to present argument before the jury or assist in witness examination.
¶8 At trial, the jury heard evidence that Mr. Regan had driven his eight-month-pregnant girl friend, Ronna Bruce, to the hospital at 8 p.m. on September 19, 2005 for treatment of a 104 degree Fahrenheit fever. He was returning to visit Ms. Bruce in the early morning of September 20 when he was pulled over. Mr. Regan testified that the car was not his but his girl friend’s and claimed that he never noticed a camera case in the front passenger seat that day.
¶9 The State called Mr. White as part of its case in chief. After again hearing argument on Mr. White’s objections to *425testifying, the court ruled that the communication was not privileged and ordered him to testify. Witnesses other than Mr. White testified that Mr. Regan received notice of the conditions of his release requiring his attendance at trial as well as a trial scheduling order indicating that his trial would begin on March 7, and that he was in court on March 7 for the trial readiness docket, where he was informed that trial was to begin the next morning at 9 a.m. The State also presented evidence outside of Mr. White’s testimony that when Mr. Regan was not in court on March 8 at 9 a.m., that the court recessed at 9:21 a.m. to give Ms. Vasiliades a chance to locate Mr. Regan. When the court reconvened at 9:34 a.m., the judge released the jury panel and issued a bench warrant for Mr. Regan’s arrest before recessing at 9:49 a.m.
¶10 Mr. Regan presented evidence that he arrived at court and met with counsel at approximately 10 a.m. on March 8. The State presented evidence through Mr. Regan’s neighbor that Mr. Regan did not leave for court until 9:15 or 9:30 a.m. on March 8, and that it is a 30-minute drive from Moses Lake to the courthouse in Ephrata.
¶11 The jury convicted Mr. Regan on all four counts after a two-day trial.
Discussion
¶12 On appeal, Mr. Regan contends that his rights were denied under the Sixth Amendment, which provides a criminal defendant with the right to effective assistance of counsel at trial. U.S. Const, amend. VI. This right includes the entitlement to representation that is free from conflicts of interest. Strickland v. Washington, 466 U.S. 668, 688, 104 S. Ct. 2052, 80 L. Ed. 2d 674 (1984); State v. Dhaliwal, 150 Wn.2d 559, 566, 79 P.3d 432 (2003) (citing Wood v. Georgia, 450 U.S. 261, 271, 101 S. Ct. 1097, 67 L. Ed. 2d 220 (1981)).
¶13 The trial court has a duty to investigate potential attorney-client conflicts of interest if it knows or *426reasonably should know that a potential conflict exists. Mickens v. Taylor, 535 U.S. 162, 167-72, 122 S. Ct. 1237, 152 L. Ed. 2d 291 (2002) (citing Holloway v. Arkansas, 435 U.S. 475, 98 S. Ct. 1173, 55 L. Ed. 2d 426 (1978); Cuyler v. Sullivan, 446 U.S. 335, 100 S. Ct. 1708, 64 L. Ed. 2d 333 (1980); Wood, 450 U.S. 261). Reversal of a conviction is required if a defendant or his attorney makes a timely objection because of a claimed conflict and the trial court fails to conduct an adequate inquiry. Holloway, 435 U.S. at 488. But if the defendant does not make a timely objection in the trial court, a conviction will stand unless the defendant can show that his lawyer had an actual conflict that adversely affected the lawyer’s performance. Cuyler, 446 U.S. at 350; Wood, 450 U.S. at 272-74. A harmless error analysis is not required. Holloway, 435 U.S. at 489 (quoting Chapman v. California, 386 U.S. 18, 23, 87 S. Ct. 824, 17 L. Ed. 2d 705 (1967)). The State argues that prejudice must be shown. We disagree.
¶14 In Mickens, the United States Supreme Court criticized lower courts that “ ‘unbhnkingly’ ” applied these conflict of interest rules to “ ‘all kinds of alleged attorney ethical conflicts,’ ” rather than a Strickland analysis, which requires a showing of both deficient performance and prejudice. Mickens, 535 U.S. at 174 (quoting Beets v. Collins, 65 F.3d 1258, 1266 (5th Cir. 1995)). The Court noted that it had applied the conflict of interest rules in cases of multiple concurrent representation, but the issue of whether those rules are properly extended to other cases was, as far as the jurisprudence of the Supreme Court was concerned, an open question. Id. at 175-76.
¶15 This is not an open question, however, in Washington. In In re Personal Restraint of Richardson, 100 Wn.2d 669, 675 P.2d 209 (1983), overruled on other grounds by Dhaliwal, 150 Wn.2d at 568, an attorney represented both a witness and the criminal defendant. The court held: “The application of these [conflict of interest] rules is not limited to joint representation of codefendants. While most of the. cases have involved that fact situation, the rules *427apply to any situation where defense counsel represents conflicting interests.” Richardson, 100 Wn.2d at 677 (emphasis added). More recently, in State v. McDonald, 143 Wn.2d 506, 513, 22 P.3d 791 (2001), where there was a conflict of interest between a defendant and standby counsel, the court held: “These [conflict of interest] rules apply to any situation where defense counsel represents conflicting interests.”
¶16 As to the application of the conflict of interest rules in cases where defense counsel is called as a witness, our courts have recognized that “[t]he right of the prosecutor to call defense counsel as a witness is within the broad discretion of the trial court; however, a weather eye must be kept on the constitutional rights of the defendant in a criminal trial at all times.” State v. Stiltner, 61 Wn.2d 102, 104, 377 P.2d 252 (1962). “There must always be a sensitive balance between the right of the state to prove its case, in the best manner possible, and the right of the accused to have unhampered and effective representation.” State v. Sullivan, 60 Wn.2d 214, 221, 373 P.2d 474 (1962). Mr. Regan’s Sixth Amendment claim is properly considered under the conflict of interest rules.
¶17 In order to establish any violation of the Sixth Amendment based on a conflict of interest, a defendant must demonstrate that an actual conflict of interest adversely affected his lawyer’s performance. Cuyler, 446 U.S. at 348; Richardson, 100 Wn.2d at 677. If this standard is met, prejudice is presumed. Richardson, 100 Wn.2d at 677; Dhaliwal, 150 Wn.2d at 568.
¶18 In Dhaliwal, our Supreme Court clarified the analytical framework for determining whether counsel labored under an actual conflict of interest in violation of the Sixth Amendment. Dhaliwal, 150 Wn.2d 559. Notably, the “ ‘standard is not properly read as requiring inquiry into actual conflict as something separate and apart from adverse effect.’ ” Id. at 571 (quoting Mickens, 535 U.S. at 172 n.5); see also United States v. Rodrigues, 347 F.3d 818, 823 & n.7 (9th Cir. 2003) (rejecting dual inquiry). An “ ‘actual con*428flict’ ” is “a conflict that affected counsel’s performance — as opposed to a mere theoretical division of loyalties.” Mickens, 535 U.S. at 171 (emphasis omitted); see also United States v. Baker, 256 F.3d 855, 860 (9th Cir. 2001) (noting that an “ ‘attorney has an actual, as opposed to a potential, conflict of interest when, during the course of the representation, the attorney’s and the defendant’s interests diverge with respect to a material factual or legal issue or to a course of action’ ” (quoting United States v. Levy, 25 F.3d 146, 155 (2d Cir. 1994))).
¶19 In order to show adverse effect, therefore, Mr. Regan need not demonstrate prejudice — that the outcome of his trial would have been different but for the conflict — but only “ ‘that some plausible alternative defense strategy or tactic might have been pursued’ but was not and that ‘the alternative defense was inherently in conflict with or not undertaken due to the attorney’s other loyalties or interests.’ ” United States v. Stantini, 85 F.3d 9, 16 (2d Cir. 1996) (quoting Winkler v. Keane, 7 F.3d 304, 309 (2d Cir. 1993)). Thus, the conflict (1) “ ‘must cause some lapse in representation contrary to the defendant’s interests,’ ” State v. Robinson, 79 Wn. App. 386, 395, 902 P.2d 652 (1995) (quoting Sullivan v. Cuyler, 723 F.2d 1077, 1086 (3d Cir. 1983)), or (2) have “likely” affected particular aspects of counsel’s advocacy on behalf of the defendant, United States v. Miskinis, 966 F.2d 1263, 1268 (9th Cir. 1992).
¶20 Whether the circumstances demonstrate a conflict under ethical rules is a question of law, which is reviewed de novo. State v. Vicuna, 119 Wn. App. 26, 30-31, 79 P.3d 1 (2003); State v. Ramos, 83 Wn. App. 622, 629, 922 P.2d 193 (1996).
¶21 Here, the conflict was brought to the trial court’s attention in a pretrial hearing when Ms. Vasiliades explained to the court her dilemma in agreeing to a trial continuance in order to accommodate Mr. White’s vacation, which resulted in Mr. Regan’s extended pretrial detention: “On the one hand my supervising attorney has a material witness warrant for him if I say that I want to go to trial *429this week, on the other hand, the defendant wants to go to trial and I believe he has that right.” RP (Apr. 4, 2006) at 20.
¶22 Ms. Vasiliades ultimately agreed to the continuance, to the consternation of her client. This is a classic example of a choice between alternative courses of action that was helpful to defense counsel’s own interests and harmful to Mr. Regan’s. And it shows an actual conflict of interest. See State v. James, 48 Wn. App. 353, 366, 739 P.2d 1161 (1987) (“ We will not find an actual conflict unless appellants can point to “specific instances in the record to suggest an actual conflict or impairment of their interests” [(quoting from United States v. Fox, 613 F.2d 99, 102 (5th Cir. 1980))].’ ” (alteration in original) (quoting United States v. Mers, 701 F.2d 1321, 1328 (11th Cir. 1983)). The trial court in this case was on notice that an actual conflict of interest existed, which was adversely affecting Mr. Regan’s representation.3
¶23 In Sullivan the Washington Supreme Court held that defense counsel’s compelled testimony was repetitious of other testimony and unnecessary to the State’s case when balanced against the need for the testimony:
If defense counsel is required to testify under compulsion, it might well be that defendant’s right to complete and unhampered representation is invaded. Balanced against this, however, is the possibility that defense counsel’s testimony is necessary to the state’s case in the interest of justice and for the protection of the public.
Sullivan, 60 Wn.2d at 220.
*430¶24 The trial court in this case thought about balancing the competing interests, but ultimately decided that the analysis was not necessary. The court stated:
Okay. Well, if I’m in error on the following proposition, then I’m in error. There’s now argument that I should factor in whether there’s other available witnesses and if there is not other witnesses, then maybe the attorney could be called, but if there are other witnesses, maybe the attorney shouldn’t be called. I’m not sure what doctrine would provide for that sort of analysis.
RP (May 4, 2006) at 174.
¶25 On the contrary, Sullivan provides for, indeed compels, this analysis. Sullivan, 60 Wn.2d at 220-21.
¶26 The court’s order compelling Mr. White’s testimony, without seeking a waiver or making the necessary inquiry, placed defense counsel in a conflict position. Under these circumstances automatic reversal is required without a separate showing of prejudice.
f27 At oral argument on appeal, the State emphasized the need for Mr. White’s testimony to prove knowledge. But such emphasis on the necessity for the testimony only highlights the need for the trial court to balance the competing considerations.
¶28 Taking a contrary position in its briefing, the State argued that because Mr. White’s testimony was uncontested and cumulative, having Mr. White testify did not interfere with Mr. Regan’s defense strategy. But that is not the standard.
¶29 It is only when defense counsel’s testimony is both necessary and unobtainable from other sources that counsel may be called as a prosecution witness. Id. at 221. The State failed to show any need to compel defense counsel’s testimony. If it were necessary and unobtainable from other sources and the attorney’s testimony would only be corroborative, the court was required to weigh the competing interests of Mr. Regan’s right to complete and unhampered representation and the necessity of the testimony to the *431State’s case in the interests of justice and for the protection of the public. Id. at 220.
¶30 Sullivan also considered the Rules of Professional Conduct. Sullivan, 60 Wn.2d at 220. Former RPC 3.7 (1985) provides: “Alawyer shall not act as advocate at a trial in which the lawyer ... is likely to be a necessary witness except where: (a) The testimony relates to an issue that is either uncontested or a formality; ... or (c) The lawyer has been called by the opposing party and the court rules that the lawyer may continue to act as an advocate.” As to subsection (a), the issue (Mr. Regan’s knowledge) was contested. What the prosecutor intended to imply by the uncontested fact (the substance of the communication) is an aspect not covered by the rule. “An attorney must withdraw when it is likely he or she will present testimony related to substantive contested matters.” State v. Nation, 110 Wn. App. 651, 659, 41 P.3d 1204 (2002) (emphasis added). As concerns subsection (c), while the court did allow Mr. White to continue to act as an advocate, the court’s ruling did not include the necessary balancing of the competing interests. Sullivan, 60 Wn.2d at 220.
¶31 Finally, the State argues that the defense waived any claim of error by Mr. White’s election to continue as Ms. Vasiliades’ second chair. See supra note 3 (discussing waiver). In other words, the State suggests that Mr. Regan invited the error when he could have avoided the conflict. This misses the point. Mr. White would not be placed in the position of testifying and Ms. Vasiliades would not be placed in the position of examining him had the trial court properly weighed the competing interests while it considered Mr. White’s motion to quash the subpoena. See Sullivan, 60 Wn.2d at 220.
¶32 When considering the damage to the defendant’s relationship with counsel, the court in Sullivan held that “[d]efense counsel’s presence, as an unwilling witness for the state, rendered his services less effective and invaded the accused’s right to unhampered representation at the trial.” Id. at 221. We join other courts that have held: *432“We are persuaded that putting defense counsel in the position of a prosecution witness is something that ‘should be avoided whenever possible.’ ” Venable v. State, 108 Md. App. 395, 672 A.2d 123, 128 (1996) (quoting Kaeser v. State, 96 Nev. 955, 620 P.2d 872, 874 (1980)); accord State ex rel. Sowers v. Olwell, 64 Wn.2d 828, 834, 394 P.2d 681 (1964).
¶33 Reversed.
Stephens, J. Pro Tem., concurs.
Mr. Regan pleaded guilty to third degree driving with a suspended license. That conviction is not a part of this appeal.
During oral argument on appeal, Mr. Regan’s counsel mentioned that Mr. White filed a notice of appearance. The State’s motion to supplement the record with Mr. White’s written notice of appearance was later granted by the court, which showed this appearance was entered on May 4, 2006. An appearance in writing, however, is not required. CR 4.2(b) (“Representation of the person by the attorney at any proceeding before a judge, magistrate, or other judicial officer on behalf of the person constitutes an entry of appearance pursuant to RCW 4.28.210 and CR 4(a)(3).”). Mr. White’s appearance was secured on or before March 8,2006.
Alternatively, this colloquy and others in the record could be viewed as defense counsel’s acknowledgment of a conflict of interest. Trial courts may allow an attorney to proceed despite a conflict of interest “if the defendant makes a voluntary, knowing, and intelligent waiver.” Garcia v. Bunnell, 33 F.3d 1193, 1195 (9th Cir. 1994). For a conflict waiver to he knowing and intelligent, the defendant must have been “ ‘sufficiently informed of the consequences of his choice.’ ” Evans v. Raines, 705 F.2d 1479, 1480 (9th Cir. 1983) (quoting Hodge v. United States, 414 F.2d 1040, 1042 (9th Cir. 1969)). The court must “ ‘indulge every reasonable presumption against the waiver of fundamental rights.’ ” United States v. Allen, 831 F.2d 1487, 1498 (9th Cir. 1987) (quoting Glasser v. United States, 315 U.S. 60, 70, 62 S. Ct. 457, 86 L. Ed. 680 (1942)). Obviously, there was no waiver here.
