[mythtv-users] Low volume on second PVR-150

Fri Mar 3 02:13:02 UTC 2006

I could swear I saw something about this recently, but no amount of 
searching the archives has turned it up.

I just installed a second PVR-150 card in my 0.19 system.  I have a 
couple of questions, but one main problem:

The audio level on one of the cards (I'm a bit confused about which card 
it is -- that's part of one of my questions which I'll save until later) 
is now noticeably lower than the other.  The "good" card seems to have 
audio levels consistent with what I remember (i.e., put the receiver 
volume knob at 8 O'clock for comfortable listening).  The other card 
needs to be cranked up another few notches to be loud enough.

This is true of both livetv and recordings.

Grateful for any tips on what to look for (and/or pointers to that 
recent thread if someone else recalls it).  relevant dmesg output below.

Cheers,
john
