Recently after my system updated packages, I restarted my computer and found that sound no longer works. aplay -l
and pulseaudio both report that there are no sound devices, even though they were working fine previously.
I checked and found that the proper kernel modules were not loaded. Running sudo modprobe snd_hda_intel
got my motherboard's sound device to immediately show up in pulseaudio, and sudo modprobe snd_usb_audio
got my USB audio devices working as well.
I haven't edited any audio configuration files recently, but I'd like to get this working automatically so that Ubuntu will load the proper kernel modules at boot time after detecting my hardware.
