Nforce 4 MSI motherboard integrated sound----since my Creative X-Fi isn't supported, YET
can not get the front center speaker to work.

Here is my present asound.conf file that I created in /etc for my Debian etch 4.0----amd64 system X2-4200-cpu
# Set default sound card # Useful so that all settings can be changed to a different card here. pcm.snd_card { type hw card 0 }

Here is my back up with other configurations for the file that created the same 4 speakers and subwoofer sounds but no front center speaker sounds
pcm.ch51dup { type route slave.pcm dmix6 slave.channels 6 ttable.0.0 1 ttable.1.1 1 ttable.0.2 1 ttable.1.3 1 ttable.0.4 1 ttable.1.4 1 ttable.0.5 1 ttable.1.5 1 } ########Old Setup # pcm.51to40 # { # type route # slave.pcm surround51 # slave.channels 6 # # # Front and rear, at 75% of original signal strength # ttable.0.0 0.75 # ttable.1.1 0.75 # ttable.2.2 0.75 # ttable.3.3 0.75 # # Center channel routing (routed to front-left and front-right), # 6dB gaindrop (gain half of main channels) per channel # ttable.4.0 0.375 # ttable.4.1 0.375
# LFE channel routing (routed to front-left and front-right), # 6dB gaindrop (gain half of main channels) per channel # ttable.5.0 0.375 # ttable.5.1 0.375 # }
When I changed a setting from Autodetect to ALSA I could not get any sound--so I compiled everything from source with the latests tars and still nothing, and once I turned the Autodetect in Multimedia Systems Selector<Preferences<Desktop for the Default output plugin, I still had no sound in my center front speaker.
Whew.
I'd love it for my Creative X-Fi card to be supported, but right now, I really like my front center speaker back. I'm at the end of my list of possible fixes, maybe someone who understands can take a look at this an have a go
