Bug ID: 54543
           Summary: Avantree Leaf USB audio device does not play sound in
                    applications run via wine
           Product: Wine
           Version: 8.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

I'm using an USB audio device called "Avantree Leaf" to pass audio via
Bluetooth to a receiver.
After this change in the kernel
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h...
applications run by wine via the pulseaudio output cannot initiate a stream on
the audio device and there is no sound. To test, I've used the audio player
foobar2000, but it's the same for other Windows applications. Native Linux
applications work without problems so far.
The latest Wine version that I tested is 8.1, but I haven't found any between
Wine versions in this regard.
It also does not work, if I select the usb device specifically in winecfg or in
foobar2000 itself. I do however get sound if I select another device, e.g. my
onboard sound card or the HDMI output, thus I know it is a problem with the usb
device only.
I usually use pipewire/wireplumber as an audio server with pipewire-pulse as a
Pulseaudio replacement, but the problem also exists if I'm using standard
Pulseaudio instead.
There are two possible workarounds that I can use to get sound from the device
when running Wine application:
1. Disable the usb audio latency management by loading the module with the
parameter lowlatency=0
2. Set clock.min-quantum 512 in pipewire/wireplumber, which I think also
increases the latency a bit
The maintainer of the kernel usb audio driver thinks that this an application
problem and that the kernel driver is working correctly. Therefore, I'm now
opening this bug report.
The corresponding bug report on the kernel side is, there I also have some
additional information available, not sure if I should replicate all of that
here:
https://bugzilla.kernel.org/show_bug.cgi?id=216909
Also, see this discussion on a pipewire issue, which was the first report I did
about this:
