MythTV Audio Problem

Hello,

I have just finished building a MythTv box and am overall happy with the progress. I am fairly experienced with Linux,
but more on the command line and programming levels. I first tried to use Fedora 10 with the MythTv software set up by hand. After encountering numerous problems I
switched to the newest version of Mythbuntu. This fixed almost all
of my problems, except one, I can hear the TV audio even when not in "Watch TV".

My system is using a pcHDTV HD-5500 combination NTSC/ATSC/QAM tuner card. I have analog
cable and am only using the analog tuner currently. To get audio when in analog mode a pigtail is connected from the card to
the line-in on the motherboard. I then have the speaker-out connected to the
TV. The problem is that I can hear the audio of whatever
channel I was watching (or static if the card is not tuned to a channel)
even when MythTv is in the main menu (i.e. not recording or watching live TV). Has anyone else encountered this problem before?

The documentation that came with the card says that the pigtail
is required when using the analog tuner. I also tried to unplug it
and couldn't get any audio with it unplugged.

I'm thinking it is an OS problem. When I was working with
Fedora 10, I couldn't get MythTv to work but was able to use
tvtime to test the card. The audio worked correctly then. I
have not changed any hardware connections, just installed
a different OS.

I was able to solve the problem. The card apparently does put
analog audio out without the pigtail. This is not mentioned in
the instructions however . I will still try to experiment because
the audio does not sound as good as with the pigtail.

Thank you.
