The rear and center channels on my 5.1 speakers don't work.
I've checked the connections a few time, and turned up volume sliders in alsamixer
“System information” in alsamixer correctly identifies the card as
X-Fi Extreme Audio [SB0790] at 0xdc00 irq 21
When I try
sudo alsactl init
I receive error:
alsactl: parse:1655: Unable to open file '/usr/share/alsa/init/ca0106': No such file or directory
What is this file, could this be the problem, how do i fix it?
I'm running Debian squeeze amd64.
