Description of problem:
see %subj% ... both with and without Pulseaudio running (I would prefer it running, to be honest) I don't get any sound from speakers of my notebook. Headphones work just fine, but when pull jacks out of the computer, loudspeaker doesn't pick up the sound (neither it works after startup without any headphones used).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce: anything without headphones plugged in
Actual results:
no sound

Expected results:
just playing as it does to headphones

discussed at blocker meeting today; we can't really put bugs like this on the blocker list, unfortunately, we're not at the point where we can delay releases for system-specific audio problems like this.

can you confirm you've run 'alsamixer -c0' and twiddled with all the controls there to see if it's just a volume setting issue? if so, can you test with the following in /etc/modprobe.d/alsa.conf :

options snd-intel-hda model=auto

and see if it changes anything?

(Jaroslav, I don't see any model= options documented for Conexant CX20561 in HD-Audio-Models.txt , so I don't know which other parameters to suggest...)

With a lot of googling, I tried to add this /etc/modprobe.d/alsa.conf

options snd-hda-intel model=laptop enable_msi=1

(I had terrible number of errors in dmesg|grep DMA related to this device), but the situation has not changed. Still headphones are playing lovely, speaker is silenced.

It was PEBKAC in the end, too embarrassing to admit what actually happened ;).
