[mythtv-users] Very low volume when recording -- Can I fix this?

I have capture working for both these cards so here's my $.02.

As Isaac mentioned, it is "Capture" that controls the volume
level for recording from the input marked for CAPTUR. The
Line-in level should only affect the patched through analog
sound when Line-in is unmuted.

The SB Live is a little trickier because more than one Capture
slider affects the record level. There seems to be one general
"Capture" slider then several other sliders to control the
capture level for each different type of input source ("Wave
Capture", "Surround Digital Capture", "IEC958 Optical Capture").
In order to get a normal record level I have to turn up the
volume on "Capture", AND "AC97 Capture". I also have the
"Wave Capture" turned up but I think that was for something
other than myth.
