This will probably be the shortest howto I have ever written but hopefully it will be of help to someone.

I struggled getting my 4.1 Surround system working for quite some time today until I finally upgraded to Fedora 11 (from F10). Fedora 11 is quite an upgrade in terms of the pulseaudio setup that is included but as always it is not perfect…

I am fairly sure that the setup included with fedora defaults to 2 channels of audio since it is impossible to detect your particular speaker setup.

to change the default number of channels to output to we simply have to edit this file (as root of course):
Code:

/etc/pulse/daemon.conf

look for the line that says:
Code:

; default-sample-channels = 2

Uncomment the line, and change it to whatever your speaker setup requires (i.e. 4.1 requires 5 channels, 5.1 requires 6 etc)
Code:

default-sample-channels = 5

Save the file, kill pulseaudio, and restart as daemon
Code:

[root@asdf] # killall pulseaudio && pulseaudio -D

now if you want to make sure that the changes were picked up by pulseaudio you can simply run the command ‘paman’ which is included in the default repo
