[mythtv-users] Lost Sound on PVR-350 After Upgrade to IVTV 0.4.1

[Matt Price]

kirk, i found the post below in my maibox.  this problem you describe sounds
like the one i'm having now -- i had mythtv running fine under ubuntu
breeazy for over a year, then tried to upgrade, failedsomehow, rebooted into
my old root system and suddenly no sound!  i was wondering whether you had
solved this and if so, whether you still remember how!  

as i say i htink this is the same issue -- sound OUTPUT works fine, and my
old recordings still play fine through pvr-350's tv-out; but sound input
through the capture card no longer works, there simply isn't any audio being
processed.  any idea how to fix it?  i'm at a loss, all these modules are
sorta greek to me.  

thanks,

matt
