[mythtv-users] jiffies and then the sound drops

[Jason Portwood]

Last night during recording I lost sound of a few of my tuners.  This 
error message was in the logs.

Two PVR500's writing to a RAID5 partition (software).

It turns out if I push the system I can make it do this.  I fired all 4 
tuners up at once.  Then started to encode a video, copy a lot of files 
around, and flagged commercials which was running already.

Two of the cards muted the audio - checked it with

v4l2-ctl -C mute --device=/dev/video0

Is there a fix for this?

Thanks
