I installed a new sound card, a Turtle Beach card, and can't seem to get sound out of the optical out. lspci says it is a CM8738 chip. I can get static out the front two channels with the following command but that is it so far (when the test says center, nothing works):
speaker-test -Dplug:iec958 -c 6
When sound does come out those two channels, my reciever says PCM, but when the test says other channels, it says NO AUDIO INPUT. I disable the onboard intel audio from the bios.
aplay -l says:

Currently I have the following switches checked: IEC958 5V IEC958 Output
I also tried: asoundconf set-default-card CMI8738
I don't really know very much about sound trouble shooting, so any help is appreciated. I am using Ubuntu 9.04
Update:
If I uninstall pulse, it works okay for XMBC, but nothing else has sound. Not sure what I need to do with the Ubuntu Config.
Also, my card is: Turtle Beach TBS-3300-01 Montego DDL Sound Card
