This is a second attempt to fix the bug appearing on Android with the recent kernel; the first try was ff878b408a03 and reverted at commit 79764ec772bc.
I found that full-duplex audio for Scarlett devices was broken in 5.19.11 but working again 5.19.12, presumably due to this. escuta at https://linuxmusicians.com/viewtopic.php?p=148734#p148734 reported that it was broken from 5.19.9 but 5.19.8 worked (they also reported that 5.9.12 didn't work, which I can't explain).
5.19.12 and 6.0.0 work for me, but 6.0.0 + your v2 patch makes the gnome sound settings app crash when setting the output device to Scarlett if the input device was already set to Scarlett.
Using the gnome-control-center (42.3) app (Fedora 36, PipeWire 0.3.59, WirePlumber 0.4.11) to test:
Kernel 5.19.11: can't set both input and output device to Scarlett; changing output to Scarlett makes the input device switch to something else, and changing the input device to Scarlett makes the output device switch to something else
Kernel 5.9.12 & 6.0.0: can set both input and output device to Scarlett, all good/normal
Kernel 6.0.0+v2 patch: if both input and output device are already set to Scarlett, works fine. Change output device to something else then back to Scarlett, the settings app hangs. Kill the app, restart it, the input & output device are both Scarlett & it appears to work fine again until you change the output device to Scarlett when the input device is already Scarlett. Changing it in the other order (set input device to Scarlett when output device is already Scarlett) works no problem.
Hmm. Just to be sure, could you verify the behavior with 6.0 + for-linus branch of sound git repo?
And if it still doesn't work, try the following patches in addition.
Also, pass snd_usb_audio.dyndbg=+p boot option and give the dmesg outputs while apps getting the error.
thanks,
Takashi
