Sound Configuration [OSS]

MGu3l · 2010-01-14 06:49:45

Good night everybody ... Yesterday I had to change my motherboard, since the previous board who had burned, so I changed it, I reinstalled Arch, and configured the sound but then I encounter a problem: My sound card is integrated, especifically it's an Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) . This card has 2 outputs, but only one of these works, what i mean is that only 2 of the 4 speakers sounds. Furthermore, by connecting a headset in the front of my PC, these sounds, but the two speakers also continue playing.

Also, when I log in, the following message appears 2 times in TTY oss_haudio: HDA codec 0x1106e721 not known yet .

If anyone knows what can i do do or how to configure OSS for my four-speaker sound, i'll be thankfull

I'm not sure about all four speaker, maybe open ossxmix and change vmix0-channels to multich instead of stereo. As far as plugging your headphones in and still hearing sounds from the speakers at the same time, I have to use an alias in my .zshrc (also used in .bashrc), so when I type mix2 it directs sound to my speakers and when I type mix3 it directs sounds only to the headphones. You can bind these to hotkeys too.

alias mix2='ossmix codec1.jack.int-speaker.mode mix2' #Mixer set to PC Speakers
alias mix3='ossmix codec1.jack.int-speaker.mode mix3' #Mixer set to Headphones

You may have to change the values depending on your setup. You can check the output of ossmix in your terminal to see the values. As far as I know OSS doesn't auto-detect headphones when they're plugged in so you have to do it manually.

Oh yeah, and when OSS starts up and gives you a message about ".. codec not known" it just means exactly that: your sound card isn't specifically known but most of the time OSS still knows how to use it.

thanks for your answer...

today i use the command osstest, and realize that all the seakers sound, but when i use mplayer or mpd, only two of them sound...

osstest

i don't know hot to enable this /dev/oss/oss_hdaudio0/pcm1 (audio engine 1): HD Audio play pcm2 to sound all the time, since it didn't appears in ossxmix
