Hello fellow alsa users!
I have a M-Media CM8768 based PCI soundcard. It has 8 channels. On this
card there are jacks for all 8 speakers in addition to line in and mic.
I am having problems getting all the channels to work correctly.
If I do:
speaker-test -D surround71 -c8 -twav
all channels work - center front , sides L/R, rear L/R and center rear
-- except the front left and right
also, if i do
speaker-test -D surround51 -c6 -twav
the selected channels work fine -- except the front left and right.
but if i do
speaker-test -D front -c2 -twav
the front speakers work (only)
aplay -D surround51 -c6 A6channelfile.wav
yields the same results.
I do not have an .asoundrc file (i think that may be needed? to route
thees channels?)
Also I had a ensoniq card with 4 channels that worked fine before I got
this one.
All I really need is 5.1 for now..
I was up till 4:00AM with this I hope some one can help :)
Below is gobs of info on my setup. Let me know if you need more.
Thanks in advance
Stan
