When pulseaudio is installed, and enabled, you only see one control when
opening alsamixer on the CLI. To see all controls for your soundcard, open
alsamixer as below. This assumes you only have one soundcard on the machine.
alsamixer -D hw:0
I've just seen you also have a firewire card. I've no experience with
firewire, but you could try alsamixer as below, if it's correctly detected as
a second soundcard.
alsamixer -D hw:1
Post back the output of: cat /proc/asound/cards
Pulseaudio, itself, can be a pain in the backside, and can create more
problems than it's supposed to be able to resolve. To disable it do the
following. You can always re-enable it later, if you want it.
Using Yum:
yum remove alsa-plugins-pulseaudio
If you also have KDE, this will also remove, kde-settings-pulseaudio.
Using Apt:
apt-get remove alsa-plugins-pulseaudio
Same as above if you also have KDE installed.
Nigel.
btw: sound does work on linux, but sometimes it just takes a bit of time to
get it sorted out.
