Hi,

I was trying to find an answer for my problem on the web...but with no result. I have Fedora core 5 and the sound works, but not as i would like.
I have a sound system and need to have working all three channels as output. Sound is coming only from one channel so subwoofer and the other speakers are dead.

Not sure what to install, I have Sound on board, AMD SiS series chipset...

Anyone can help me?.....MANY THANKS

do you need to turn up the controls in alsamixer?

thanx for Your reply,

In the alsamixer the controls are up, nothing is muted, 6 channel is selected....
In volume controls I have ALSA as device selected. I tried the xmms also the Rythmbox player, but I hear only the front speakers.
When I run the alsa test, everything seems to be ok, I hear an undefinable sound changing from one speaker to another, also the surround...

I m pretty a newbie to linux, I tried to find the solution somehow alone, but now I m stuck...

any idea will help. thx again

what exact chipset do you have? post the output of 'lspci' (run as root)
do you have the right driver loaded? post the output of 'lsmod'
does this hardware work the way you want, in another operating system?

the recognized chipset is intel ICH [SiS SI7012], actually its the amd SiS series on board sound.
I have also win Xp and there its ok.

ok, I also typed the commands you advised, but im not sure what to do..

ok, I geve up.
I m not sure bout it. ANY SUGGESTIONS?
how do you run your 5.1 sound...???

run the 'lsmod' command and copy and paste the output in a response at this thread so we can see what driver its using.
also check out here. or search google.com/linux or see the HCL here at lq.org and see if your card is mentioned and see if anyone else figured out the 5.1 issue. i think the first link talks about this.
please post back with the output from the command thanks
