[mythtv-users] Mythtv & ALSA sound in one channel only

[Graeme Woollett]

I'm running 2.4.20-20_29 with mythtv-0.12, and a SBlive (I had the 
problem with 0.11 as well) .
When the machine has booted I run this script.
#!/bin/sh
amixer -c 0 sset Mic,0 40% unmute cap
amixer -c 0 sset Line,0 40%,40% unmute cap
amixer -c 0 sset Capture,0 40%,40% unmute cap
amixer -c 1 sset Mic,0 40% unmute cap
amixer -c 1 sset Line,0 40%,40% unmute cap
amixer -c 1 sset Capture,0 40%,40% unmute cap
#amixer -c 0 set Master,0 100%,100% unmute
#amixer -c 0 set Line,0 75%,75% mute captur
#amixer -c 0 set Capture,0 100%,100% mute captur
#amixer -c 1 set Master,0 100%,100% unmute
#amixer -c 1 set Line,0 75%,75% mute captur
#amixer -c 1 set Capture,0 100%,100% mute captur
v4lctl -c /dev/video0 volume mute off
v4lctl -c /dev/video1 volume mute off

Not matter what I try the audio is only comming out of the RH speaker!  
I did a fresh install of everything and the problem went away.
I've looped the tv audio out from the tv card to the sblive line in.  
The cable is fine!
Now it's back, no  changes to the sound setup have been made.  Playing 
music from ogg is not a problem so its a capture related issue.
I saw a thread in the archives in which some people where having the 
same problems but it didn't appear that there was a solution.

On another front I have 2 tv cards, one a an saa7134 and the other an 
bt878 based one.
With mythtv-0.11 these recorded simultaneously without problems.  Since 
I've upgraded to 0.12 I either get a mythbackend segmentation fault or
it just hangs.  I have an Nvida card with 4363 version nvidia driver.

Does anybody a a magic receipe that yields a stable myth box i.e kernel 
version, myth version compiled or RPM, nvidia driver version etc.
