[mythtv-users] Sound issues

So I have an hd-3000 card and a cable connecting the audio out of the 
card to the audio in of my SB live sound card.  From the documentation, 
I gather that I'm supposed have the following settings:

Line is muted and captur is enabled
PCM is at a high volume
Master is at a high volume
Capture is muted, at a high volume, and captur is enabled

Yet when I do all of this I still cannot hear any sound.  If I simply 
un-mute the line in, then i will here the non-synced live-tv sound that 
doesn't correspond with the video.  I've read some people say that Line 
must also be at zero volume, but changing it's volume has no effect.  
ALSA is enabled and I've set my audio output device to ALSA:default in 
the general setup of the frontend.  I've also unchecked the box that 
says "use internal volume controls" so that it is using an external 
mixer.  I have also tried this using the internal volume controls and 
using /dev/dsp as my audio output device.  None of these changes have 
any effects.

tvtime has no sound (unless I un-mute the line-in)
aplay /dev/dsp results in a few underruns but eventually they die 
out--no sound however.

Everyone else seems to be able to solve this problem so easily, what is 
going on here!?!
