Hi,

My system's sound is no longer is working.

No, it's not muted, the sound modules are loaded, and there are pcm's in /dev/snd but no /dev/dsp. Also, while alsamixer does show the sound cards, it is only using the null device, and pulse audo doesn't see the sound cards either. Anyone know why alsa might not be using the soudn cards?

Have you loaded the snd-pcm-oss module too?

In fact, why don't you post the output of this:

It's actually not the modules or udev, but a systemd problem. I think pulse isn't starting?

I have not been following the discussion in detail, so please excuse me if this has been covered:

Please make sure the pam_systemd module is enabled in the relevant files in /etc/pam.d/.

Cheers,

Tom

This fixed it; thanks
