im running ubuntu mini 8.10 [this guide http://forum.xbmc.org/showthread.php?tid=44019] with latest svn. i have a SB Live 5.1 card and im getting sound from Sub, Center, Rear L&R speakers, but not from Front L&R. Tried all things in alsamixer but no luck... any ideas?

Does it work fine in Ubuntu? Likely an Ubuntu config issue and not XBMC.

really cant recall, i just installed full ubuntu shortly and then went to use the mini copy. i know its mainly an ubuntu issue, but i hoped maybe someone here faced the same issue

that did it

Code:

# sudo nano /etc/rc.local

Append the following to file

Code:

echo Setting 5.1 Channel volumes...
amixer -q set Master 100% unmute
amixer -q set PCM 40% unmute  
amixer -q set Surround 100% unmute  
amixer -q set "Surround Jack Mode" "Independent"  
amixer -q set Center 81% unmute  
amixer -q set LFE 100% unmute  
amixer -q set "Mic select" "Mic1"  
amixer -q set "Mic" 65% unmute  
amixer -q set "Channel mode" "6ch"  
amixer -q set "Center/LFE Down mix" mute  
amixer -q set "Duplicate Front" mute

to configure sound levels

Code:

# alsamixer

to test speakers output

Code:

speaker-test -Dplug:surround51 -c6 [to test sound]

Also if above is not enough, then create .asoundrc in home dir
Append the following to it:

Code:

# for 5.1 speakers
pcm.ch51dup {
         slave.pcm surround51
         slave.channels 6
         type route
         ttable.0.0 1
         ttable.1.1 1
         ttable.0.2 1
         ttable.1.3 1
         ttable.0.4 0.5
         ttable.1.4 0.5
         ttable.0.5 0.5
         ttable.1.5 0.5
}

# for 4.1 speakers
pcm.ch41dup {
         type route
         slave.pcm surround41
         slave.channels 5
         ttable.0.0 1
         ttable.1.1 1
         ttable.0.2 1
         ttable.1.3 1
         ttable.0.4 0.5
         ttable.1.4 0.5
}
