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.
Regards,
Geoffrey.
