lost sound?

[Lazy-buntu]

I upgraded from Jaunty and I've got no sound. Lspci shows a sound device in there. I don't even have sound at login.

Any ideas?

What does the sound applet say

[Lazy-buntu]

I don't have a sound applet in my panel, but the volume keys on my keyboard work for mute unmute vol+ vol-

What's weird is if I go to preferences > sound > hardware, there's no hardware in there.

test your level with
alsamixer

maybe they are all at bottom

[Lazy-buntu]

Alsamixer won't even launch from terminal so I did:

aplay -l

I get: no soundcards found...

maybe this

Pulseaudio can't find working alsa sound cards on bootup.
"alsa force-reload" after login remedies the problems until next reboot.
Comments 40,41,42 propose a workaround - disabling sl-modem.
