Bug Description
Problem. after a while Pulse audio was not able to recognoze the analong internal speakers of my laptop. There is only one entery in the output section: "digital output (S/PDIF)" and obviously, it do not work.
I tried to fix the problem reading the ubuntu, debian, archlinux and gentoo manuals but there was no solution for me.
This is my temporary solution to the problem: When I plug and unplug a headphone internal speakers works again.
1. I think it's not a kernel related problem. because I did not have such a problem in different distroes I tried since 2006. Also, I 've compiled the 3.3.4 kernel and the problem was still there.
2. my speaker is not mute, I checked it in the alsamixer
3. alsactl init do not solve anything.
4. I've added these enteries to the modproe.d configuration
options snd_hda_intel enable=1
options snd_hda_intel enable_msi=0
options snd-hda-intel model=dell-m25
I've disabled the msi because few days ago when I was helping developers of the x.org to solve a radeon raelated bug, finally, we found that the disabling the msi fixes the problem. so I think my laptop is not able to handle msi well.
5. according to the ubuntu manual I tried to compile the
alsa-utils-
alsa-lib-
alsa-driver-
It was not susseccful and when I was trying to reinstal alsa from repo, libasound2 did not installed again. error is reported in the attached logs. Please help me to fix the problem.
