Title:
[P53G, VIA VT1708B 8-Ch, Green Line Out, Rear] No sound at all
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
The only modification that I made after I report this bug is in the
/etc/default/grub file, I just added in GRUB_CMDLINE_DEFAULT, the
"pci=use_cms" option, seemed to work for a few reboots but after some
reboots I have no sound in random boots, If I have sound is in poor
quality, too quietly. but in the normal cases (with no "pci=use_cms")
the sound behaves the same.
I'm use to make this in every Ubuntu boot, as I have other versions of
Ubuntu (10.04 64 and 32 bit)
In terminal I write: 'sudo alsa force-reload' If everything goes
fine I have this message:
'Unloading ALSA sound driver modules: snd-via82xx snd-ac97-codec
snd-mpu401-uart snd-seq-midi snd-seq-midi-event snd-seq snd-rawmidi
snd-seq-device snd-hda-codec-via snd-hda-intel snd-hda-codec snd-hwdep snd-pcm
snd-timer snd-page-alloc (failed: modules still loaded: snd-hda-codec-via
snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-timer snd-page-alloc).
Loading ALSA sound driver modules: snd-via82xx snd-ac97-codec snd-mpu401-uart

snd-hda-codec-via snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-timer
snd-page-alloc.'
In most exceptional cases, when everything goes fine I got this:
'Unloading ALSA sound driver modules: snd-via82xx snd-ac97-codec
snd-mpu401-uart snd-seq-midi snd-seq-midi-event snd-seq snd-rawmidi
snd-seq-device snd-hda-codec-via snd-hda-intel snd-hda-codec snd-hwdep snd-pcm
snd-timer snd-page-alloc.

snd-hda-codec-via snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-timer
snd-page-alloc.'
Then I have sound working, sometimes perfect, sometimes not, the most
of the times when I run 'alsamixer' The mixer is able to be loaded,
the same happens with amixer, sometimes not, I don't have a mixer but
the sound is working.
When It goes bad, I have the message:
'Unloading ALSA sound driver modules: snd-hda-codec-via snd-hda-intel
snd-hda-codec snd-hwdep snd-pcm snd-timer snd-page-alloc (cursor
blinking)'
and the process keeps on and on and on, and never finishes to unload
and reload the alsa modules, it can be like an hour to be unloading
the modules but never finishes.
Additional Info:
