etch : pb with sound on i810 chipset (Dell Optiplex GX270)
Hello,
I'm trying to get sound working on a Dell Optiplex Gx270.
In a previous existence (sarge + 2.6.x sarge kernel) sound was working find
on this box.
I reinstalled the box from scratch under etch (netinstall RC1) + aptitude upgrade.
Sound didn't work with kernel 2.6.18-3-686.
Upgrade to kernel 2.6.18-4-686 this morning to fix Bug#391867. This didn't fix the sound pb.
The pb is that the sound is so low (even with all the mixer settings to 100%) that
you have to put your ear on the speaker to listen to anything ...
Stuff done :
- Tested 2 sets of speakers.
- unloading/reloading sound kernel module
- cheched that there is only one sound card in the box
- checked the bios setting
- sudo alsaconf several times
- checked mixer settings (with aumix & alsamixer). The setting is not mute and pushing
volume, pcm, cd etc... to 100% doesn't improve the situation.
- ogg playing with xmms or cat /vmlinuz > /dev/audio gives the same, almost unaudible sound.
Any people out there having some understanding of alsa stuff and wants to help,
be my guest.
