Hi folks,
I'm new not only to this list but to ALSA, Ubuntu and Linux in general
so please bear with me...
I've tried to work my sound issues out myself by reading various web
resources, but I'm at a loss and hope someone can help.
Here are the results of aplay -l:
**** List of PLAYBACK Hardware Devices ****
card 0: LT [Audiotrak Prodigy 7.1 LT], device 0: ICE1724 [ICE1724]

Default Audio Device
What I want is digital out to my receiver. Anything else is gravy.
Sometimes I have gotten sound working from a mediaplayer, but nothing
for system sounds or stuff embedded in Firefox. My specific questions
(or groups of questions) are these:
1) In alsamixer the chip listed is "ICE 1724 - multitrack." Isn't that
the analog part of the card (device 0)? Don't I want device 1? How can I
change that? Is that dictated by the default device settings seen above?
As you might expect, the IEC958 Out setting in the alsamixer is stuck on
mute.
2) One of the previous times I had sound working, I noticed the default
mixer tracks ofered at the bottom of the sound preferences window were
Audiotrak Prodigy 7.1LT (ALSA Mixer) and IEC958 (OSS Mixer). That had me
really confused. Don't I want to be able to control the IEC958 output
with the ALSA mixer?
3) I created an asound.conf file in my home directory with the following
contents:
pcm.card0 {
type hw
card 0
device 1
}
ctl.card0 {
type hw
card 0
device 1
}
It has not helped....
Any advice is appreciated!
