Hi All,
I've been testing pulseaudio-3.0 and now I have some questions. Is there
any updated documentation available describing the usage of UCM in
pulsaudio and can the current UCM implementation handle multiple
soundcards? I plan to use two or three soundcards (all having there own
UCM configuration) and I'd like to use them with "module-loopback".
During testing I also run into some issues. With my current
configuration [1], I get a double-free, due missing modifiers. I solved
this with the attached patch [2]. But then I hit the assertation in file
src/modules/alsa/alsa-ucm.c function ucm_get_device_property:250
pa_assert(device->playback_channels || device->capture_channels);
I assume that this is the result of some missing entries in the UCM
config, but I can't see my issue.
Thanks,
Soeren
