[mythtv-users] No video

You were right Bruce, I made the changes I wanted to modules.conf
to correct the broken default install of ALSA, rebooted, and suddenly 
I had working video on Myth.  Now I need to get the recording of sound
sorted out.  I have two sound cards in this box, and the SBLive! is the
second card.  I am trying to work with the second card, and still haven't
gotten any sound out of myth yet.  When I run aplay /dev/dsp when myth is
running, I get nothing.  aplay /dev/dsp1 when myth is running, has a 
bitstream it's trying to play, but I can't hear it.  Is there a switch 
to change aplay's output to the second card?  I haven't had a chance to
dig into aplay's man page yet.  Also have been playing with alsamixer
to set the sound card inputs and outputs.  SBLive has a TON of mixer
sliders.
I'm not sure I'm getting the right ones.  I muted what I thought was
line-in,
and also set it to capture on that.  How can I be sure it's correct?
