[mythtv-users] Mythtv PVR-150 recording volume too low

[Stephen G]

I was hoping that someone could please help me...  
 
I have have played some of the recordings from my mythtv pvr-150 box, and I get almost no volume.  The picture is good, but I don't know why the recordings have almost no sound.
 
I set up a mythtv recording box to remotely capture programs in Canada and then nuvexport/compress them, and transfer the recordings to where I am living in the UK.  I even tried transferring the mpeg file directly recorded by mythtv and same problem.  If I remember correctly, the sound was OK when watching live TV before leaving Canada, so I don't know why the recording volume is so low.  I set the recording profiles from 90 to 100% and my alsa config (running ubuntu breezy, onboard sondcard) and it looks like this:
