I have the same problem with what I think is the same chipset:
VIA EPIA Mini-ITX motherboard, the manual says VT1616 six channel AC'97
Codec, which I think is embedded in the VT8235 South Bridge.
If I play a stereo source, I get full volume from the green output, and
lower volume audio from the blue output (and nothing from the RED). This
occurs when playing to either hw:0,0 or hw:0,1 (if I read the docs right
this is not what should happen, 0,0 should give me normal behavior,
where the blue jack is line in, 0,1 is what should be 5.1 mode).
I am new to alsa, so I could be doing something wrong.
this is the asound.conf I am using to test it:
pcm.dmix01 {
type dmix
ipc_key 1024
slave {
pcm "hw:0,1"
period_time 0
period_size 1024
buffer_size 4096
rate 48000
}
bindings {
0 0
1 1
}
}
pcm.dmix23 {
type dmix
ipc_key 1024
slave {
pcm "hw:0,1"
period_time 0
period_size 1024
buffer_size 4096
rate 48000
}
bindings {
0 2
1 3
}
}
If I do 'alsaplayer -d dmix01 <mp3 song>' then I hear it at full volume
from the green jack, and at a lowered volume from the blue jack. If I do
'alsaplayer -d dmix23 <mp3 song>" then I don't hear anything (but I
don't get any errors, it opens and appears to be playing). I have played
around in alsamixer quite a bit which playing a song to dmix23 trying to
find a combination which produces sound, but so far no luck.
I also tried playing alsaplayer twice in case there had to be something
playing on the first output for the second to work, but no luck, same
behavior.
My goal is to play 3 separate audio streams out the 3 output jacks.
Thanks in advance for any help on this matter, once I figure all of this
out I will add an example to the wiki.
