The default settings on my machine would populate pavucontrol
and alsamixer
with the correct audio sources and sinks,
but playing audio would not actually output sound (however, the microphone input would respond properly and record audio).
Setting the snd-intel-dspcfg.dsp_driver=1
kernel argument to force the legacy snd_hda_intel
driver would allow speakers
to work, but this would break the microphone.
Hopefully this saves someone else some time - this system is on Ubuntu 22.04.
Ensure firmware-sof-signed
is installed along with linux-firmware
.
