[mythtv-users] Audio query (fwd)

[Bob Purdon]

Hi guys,

I've just installed the latest KnoppMyth installation on a machine here. All 
work well, except for the audio :-(

Audio generally works on the machine - I can play MP3's, and AVI files play 
just fine.

The problem is audio from the TV capture card.  I have free to air plugged into 
the TV input on the card, and pay-tv plugged into the S-Video input.

Generally no issues with the pay-TV - I have to manually select the line-input 
on my sound card, but once I get things working I can use an external command 
to do that for me.  The audio from the pay-TV is connected to the line-in on 
the sound card (fed directly from the pay-TV decoder).

The real issue is getting audio from the free-to-air - the TV card has an 
analogue audio out.  This is connected to the MIC in on the sound card. 
Additionally, it has an output on the card itself that I've connected to the 
AUX on the sound card (but either way, the result is the same).

What I find is that in MythTV, I get video but no audio (and no amount of 
tweaking the mixer settings fixes it, mostly because I've confirmed there's 
actually no audio leaving the TV card).

If I fire up xawtv, I get audio, but no video!  (although both were working in 
xawtv yesterday).

If I fire up xawtv, then MythTV (at the same time), and then kill xawtv, I seem 
to get video and audio working OK.

This is making me wonder if MythTV is failing to enable audio on the TV card.

The TV card is a generic Askey CPH061 - nothing special.  I'll get a better 
card sometime soon, but for now this is the card I want to use.

Has anyone come across this and successfully addressed it?
