Anytime I watch TV (or any recordings) there is a ringing noise in the background.  At first I thought it was some kind interference, but both kdetv and TVtime sound just fine.  I tried fiddling with the mixer according to the howto instructions to no avail.  I also listened to the /dev/dsp output using aplay according to the howto and it sounded fine too.  This seems significant as it tells me that the sound stream is getting digitized without any problems (or am I way off track?).  Any help would be much appreciated!

Can you describe the "ringing"?
Do you have a mic somewhere?
You might take a look at your mixer and fade down all faders that are
not used.
Did you try playing a MythTV recording with mplayer to see if it's in
the recording?
