I tried to run a number of SIP softphones (linphone, kphone, etc), and
just found out my problem was the mic recording device, and not the SIP
I tried to make basic testings on recording, copying from
/dev/audio|/dev/dsp to a file or to /dev/dsp as output. Every single
test returns the same:
pcm0:record:0: record interrupt timeout, channel dead
Tried in both 5.4-S and 6.0-CURRENT (from Jun 8th). Any idea what is
causing this? And how to fix it?

O also tried to set sc->duplex = 1 on /sys/dev/sound/pci/solo.c (around
line 972) but it caused my output device to not work properly as it does
when sc->duplex = 0 and the mic device still did not work anyway.
