[mythtv-users] Chaintech AV 710 sound problems

[Brian Foddy]

I received a new AV710 today in my quest to get digital
audio from myth.  However, before I attempt digital audio,
I'm trying to simply use analog output, and I'm having
problems with no sound after pausing or fast-forwarding
the video.

I'm using a Mandriva 2005 system, running PVR150/250
cards.  Kernel is 2.6.11.4.  The old sound device is deactivated.

I found some of the same symptoms in this thread
http://mysettopbox.tv/phpBB2/viewtopic.php?t=4132&postdays=0&postorder=asc&start=0&sid=505de5c2a05e21a8a8cf17ea4794162c
And setting the Multi Rate Locking either off or locking to 48000
fixes the tone quality, but doesn't do anything for the FF problems.

I had to use Aggressive Sound buffering to get anything.  With it,
it starts playing pvr files fine, but a pause or FF will stop.
After a few seconds I see streams of 
"Audio buffer overflow, audio data lost"
errors.

This seems to be a rather popular card, so its probably something
rather simple.  But not many like errors in the forums.

I'm running a development snapshot from Dec 18, 2005 of mythtv.

Any ideas?
