Hi,

First of all, I would like to say what a great job you guys are doing wit=
h=20
this project!

Now for my little bug, which I am not sure if it is realted to the mute=20
feature not being fully complete yet.

I have an ATI rage 128 video card with the ISA TVfm tuner card. I do have=
 it=20
all working with xawtv 3.76, but when I use qtvision, I experience an aud=
io=20
bug similar to a bug I had  in earilier versions on xawtv. When I resized=
 the=20
window (or change modes), I loose audio. While resizing the window, the a=
udio=20
cuts in and out (in sync with the video display, when the screen goes bla=
ck,=20
I can hear the audio, when the picture comes back, I loose audio).=20

This is similar to what xawtv used to do during channel changes. Durning =
the=20
channel change, I would hear the audio, when the change was complete, the=
=20
audio would not be there. It took several builds before they finally got =
it=20
worked out, but I was never sure what they did to fix it.

Now, I know I am using the right mixer channel, as I can get the audio to=
 work=20
properly, if I go into configure qtvision, change the source to something=
=20
other than ntsc tuner, apply the settings, then change it back to ntsc tu=
ner,=20
and apply settings. But, if I try and resized the window (or switch modes=
),=20
the problem comes back.

I currently run slackware 8.1, xfree86 4.2 with the special ati.2 Rage th=
eater=20
drivers from gatos.sourceforge.net. I was using the kernel ess1371 drive,=
=20
then I switched to the alsa drivers (ens1371 - sb64/128). I have even=20
downloaded the oss drivers, and tested those. They all exhibit the same=20
problems.

I just wanted to get this out there, if it is realted to the mute bug, th=
en I=20
apologized for the long winded explanation.

Thanks,

brett
