View Full Version : [ubuntu] Installed OSS, still uses motherboard chipset not sound card

July 21st, 2008, 01:01 AM
I am a new Ubuntu 8.04 user with very little linux experience
I installed OSS to get my creative Xtremegamer sound card working. My motherboard has an nvidia chipset for audio which was working fine with ALSA.

I set the sound preferences under the system menu to use OSS for playback,movies, system sounds etc. But when i play an mp3 or test the system sounds I hear nothing on my speakers (they are connected to the creative sound card). If i connect them to the motherboard nvidia socket, everything works fine.

Does this mean OSS is using the motherboard chipset just like ALSA was,is there a way to get OSS to use my creative sound card instead.


The ossinfo command gives the following output.

Disable the onboard sound from the BIOS.

My bios has no option to turn off the onboard sound

Anyone, Please ?
I have already given up on trying to get my ATI Radeon X1600 AGP card to get to work, if I cant get my sound card to work either, then Ubuntu pretty much renders itself useless
