[alsa-devel] cmipci CMI8738-MC6 - left channel no sound

[Thomas Corner]

  I've been going around and around on this.  The surround sound 5.1 is
playing fine except channel 0 (front-left) is playing on the woofer. The 
card is a Terratec Aureon fun - CMI8738-MC6. I have
gotten desperate and have tested this card in Windows and was able to
get it working right there. I have been using speaker-test to
to test the setup. I am using pulseaudio.

This is the summary of my results with speaker-test:

speaker-test -c 6 -D surround51 -t wav
speaker          output
  ----------------------
  front L         silence
  front R         front R
  center          center
  bass            mix of front L + bass
  surround L      surround L
  surround R      surround R


speaker-test -c 4 -D surround40  -t wav
----------------------------------------------------
front L       silence
front R       front R
center        silence
bass          mix of front L + bass
rear L        rear L       rear R        rear R


speaker-test -c 4   -t wav
speaker-test -c 6   -t wav
speaker -test -c 2 -t  wav
---------------------------------
front L       silence
front R       front R
center        silence
bass          mix of front L + bass
rear L        silence
rear R        silence

I have removed pulseaudio again (recompiled all software with optional
pulseaudio support without pulseaudio support)  I should be outputting
directly to alsa and the driver now.

Under pulseaudio speaker-test gives error messages when surround40 and
surround51 is specified.

Thanks
