Hi,

Well the repeatable part is that when I select the second tuner with the Y 
key, the sound on the additional tuner is muted, if I then change channels on 
that tuner, the sound is restored and stays restored on all channels, I have 
only channels 5 here, until I select the original tuner. The original tuner 
(the one that is in use at start-up)  has no problem with sound at all, If I 
then go away from the second tuner, again with the Y key and then back again, 
the sound on the second tuner is again muted, and changing channels restores 
the sound.

With 0.4.0 this does not happen, at least it hasn't yet, it's been only a day 
since I have it working.

I have to say that the cards are identical, same model etc.....

When the card is muted and I do ivtvctl -Y -d /dev/video1, the data returned 
is

ioctl: VIDIOC_QUERYCTRL
Brightness = 127
Contrast = 63
Saturation = 52
Hue = 0
Volume = 58880
Mute = 0

So, I suspect that the muting is happening within mythtv only and not the 
driver.....Is that a fair assumption ??

But it's not limited to the use of the Y key, because when I record from the 
second tuner, the sound is muted also... again the use of ivtvctl -Y 
-d /dev/video1 shows the same details.
