### App version

Production

### Issue description

When connected to an external DAC, Playback does not start when play is pressed.

On the same version downloaded from fdroid and using a Pixel 10 Pro Fold, the same DAC was able to play with symfonium.

Just switched phones today to a 11 Pro Fold and the USB exclusive playback no longer works. No firmware change for the DAC.

I was using navidrome before but I’m using lightweight music server now.

The DAC (Topping DX1 II) screen flashes between DSD on and off (and 44.1 and -32db) when play is pressed.

Log captured at zefiroj-usb  
I started debug mode, then plugged in the device and pressed play. I later pressed play again. Then debug mode was turned off.

Thank you for an amazing app by the way and thank you for keeping it updated with such massive features.

### Device type

Phone

### Media provider

Subsonic (Open)

### Steps to reproduce

1. Plug in USB DAC
2. Allow Symfonium to manage the device
3. Click play

### I searched existing issues first

### I understand that logs are mandatory

### Log upload name / description

Two logs, one with old phone one with new phone

Old phone (10 Pro Fold) works just fine.

New phone (11 Pro Fold) doesn’t.

Both running Android 11, old phone has a 6.6 kernel and new phone 6.12

Good: zefiroj-good

Bad: zefiroj-bad

I waited for file uploaded successfully, lmk if you’re unable to locate the logs.

Does the dac works without usb exclusive ?

Have you installed the post release patch on the 11 fold ?

Yes it works with the other two non-usb exclusive options on the 11 Pro Fold.

Yes the system is up to date. Do you suspect it to be a system issue? I have also tried rebooting the phone a few times btw.

For what it’s worth the USB exclusive mode is really nice because then android stops yelling at me for listening at full volume on the phone (ofc DAC controls volume). The alert is apparently regulatory and impossible to turn off…

No it’s something changed in the kernel that I need to adapt to.

Will get my hands on a pixel 11 to repro and fix.

Hard to justify p11 from a p10 🙂

Got friends who planned to get one will borrow.

Awesome, is the in-app Google play thing the best way to support the app? (Especially given the fees).
