ARC unfortunately still crashes with Google Pixel 7 Pro phone and Focal Bathys in DAC mode even with the new update (1.0.40) that supposedly fixes this issue:
To narrow it down:
Many thanks for having a look into this.
Latest ARC, Pixel 6 Pro, iFi DAC/amps (iDSD nano Black Label and iDSD Diablo). Beta driver runs for around 20 sec, loses contact with the USB device. Only way to restart is to unplug and plugh back again. Crashes again after a short period. No issues with beta driver off, but SQ is quite a bit worse.
I have the same problem with Astel and Kern HC2 as well.
Hi @brian ,
Yes, mine still the same, it crashed a few seconds after I plug in the AK-HC2. I don’t understand why this DAC was working fine in previous version when beta USB driver was released and now it no longer work anymore?
Lucky I’ve the iFi Go Bar works without any issue. Probably it uses XMOS chipset for USB audio?
Hi everyone,
We pushed a fix with the most recent release for the ARC regression introduced with MUSE that causes a crash with certain USB DACs. The fix was not nearly as comprehensive as we expected; some USB DACs are still going to crash ARC, unfortunately.
Temporarily disabling MUSE may resolve these symptoms, but this is something we’ll have to do for your account on the backend.
If you don’t rely on DSP and would like to volunteer, please reach out here. Our QA team will disable this feature temporarily, quarantining the component of ARC that is breaking USB drivers.
We understand and feel your frustration and we’re working to get this resolved as quickly as you’d expect.

Hi @Gustavo_voigt,
I’ve merged your post into a tracking thread. You’re unfortunately encountering a known issue that we’ve only partially resolved with the most recent release of Roon/ARC. Please see my above comments for a potential path to a workaround, and we’ll keep posting updates here with the progress of the work to resolve this issue. Thanks!
I volunteer. You may disable MUSE for my account on the backend.
I also volunteer for going off Muse until this is fixed, as I finally have the gear to enjoy full resolution from my Pixel 6 Pro. Thanks!
Thanks for volunteering! We’re going to collect a few more in other threads before QA disables the MUSE feature - stand by and we’ll let you know as soon as we’ve flipped the switch.
Hello yes pls i would participate , i dont really use EQ on arc…
Hi, you may disable my muse as well till you are fixing the issue. I never used muse anyhow.
Thanks
Same issue with Bathys on Galaxy S20
@connor Any news on this? I’d love to use the USB driver feature!
Following…
Unfortunately no fix for Focal Bathys.
ARC still crashes immediately also with the new update (1.0.41).
AK-HC2 USB DAC, the latest build 209, still crashes immediately when plugged in. This DAC works perfectly until MUSE came along…
Hi everyone,
The team is actively investigating this issue with development still and we appreciate your patience. We’ll be posting updates over in this thread: Roon ARC Build 182 Crashing with Certain USB DACs on Android [Investigating].
If you have a) new symptoms or b) new technical details to provide, please post in that thread accordingly. Have faith that your frustration is reflected in the urgency of our internal efforts.
Note that we’ve concluded disabling MUSE is not going to restore functionality. We had initially thought this might be a workaround, but further investigation has disproven that notion. This crash concerns elements of DAC connectivity that are independent of MUSE, although the issue happened to coincide with the release of that feature.
