cmipci surround sound front-left plays on lfe

[Tom 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.  I
have a Terratec Aureon fun - CMI8738-MC6. I can redirect the output on 0
to right-front successfully using .asoundrc and "ttable.0.1 1".  I have
gotten desperate and have tested this card in Windows and was able to
get it working right there. I have been using the file
www_lynnemusic_com_surround_test.wma through mplayer and speaker-test to
to test the setup. I am using pulseaudio, but I reconfigured my system
without pulseaudio and get the same result.

Any help would be much appreciated.

And the software's front left channel is also playing on the front left
speaker?  And the subwoofer channel isn't playing on any speaker?

I do not understand how this is related to your problem.

In other words, what happens is this?

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

What happens when you run speaker-test with 4 and 2 channels?
