[pvrusb2] xawtv fix - test 2

[Mike Isely]

Regarding the audio distortion...

This might be a completely separate thing.  The pvrusb2 driver sets the 
default audio input level to maximum when it initializes.  Depending on 
which msp3400 module you are using (i.e. which kernel version you are 
using) and possibly also depending on the exact hardware model, the 
maximum input level is probably going to be a bad choice.  Probably the 
pvrusb2 driver just needs to either default the volume to about 95% of 
maximum or it should scale the setting so that "maximum" is whatever makes 
sense for the actual hardware & module combination.

Note that audio input level sticks inside the driver.  What I mean is that 
if you run, say, xawtv and back down the level, then quit and restart 
xawtv or mplayer the level will still be that same value.  In other words, 
the driver doesn't do anything to "change it back" to the default (it 
can't anyway), so this effect might be confusing some your (and Andy's) 
observations.
