[mythtv-users] newbie audio problems

[Stephen Mathezer]

I'm relatively new to mythtv, I have things sort of working but am
having trouble with audio quality.

I'm running 0.9.1 on Debian with a 2.4.20 kernel and alsa 0.9.4. I have
a Gigabyte 7VAXP which has VIA 8235 sound built in.  My capture card is
a WinTV GO.

With some screwing around I have managed to get btaudio to work with
analog output on /dev/dsp2. I am able to watch live tv and record. Sound
quality is however pretty poor no matter what I try.  There is a fair
bit of hissing and crackling all the time.

If I run xawtv and do the "sox -r 480000 -c 1 -t ossdsp /dev/dsp2 -t
ossdsp /dev/dsp" thing then sound quality is vastly better. My question
is, how do I set the sample rate that high in MythTV for both live
watching and recording? I tried actually setting the samplerate to
480000 in the codecparams table manually but that caused backend
crashes.  If I run sox all the time, then I am getting sound output all
the time which also isn't good.

I've searched through the mailing list which did help me get btaudio
going, but I couldn't find any solutions to the poor quality sound.

Can anyone help me out with this?

thanks
