[mythtv-users] Audio from inactive PVR150 tuner coming through on remote frontend

[anthonycapo at frontiernet.net]

Hi,

After upgrading to SVN (10746), I've been noticing a strange behavior 
where I can hear the audio from an inactive (i.e. not recording) tuner 
card on my frontend while in LiveTV, and sometimes even while in the 
menus. I've also noticed that the audio sometimes sounds "echo-y" on 
LiveTV and some recordings (almost like it is picking up two of the 
same audio stream).

I'm set up with one dedicated backend with two PVR-150s and two remote 
frontend-only systems. All are using ALSA or OSS.

I submitted this as a ticket (http://svn.mythtv.org/trac/ticket/2183), 
but Isaac suggested it may be a driver prolem.  However, the drivers 
are the same as I used for 0.19, and I don't know how else audio from a 
tuner card on the backend could be making it onto a remote frontend 
other than through Myth.

Has anyone else seen this behavior?  Any suggestions on how I might try 
to diagnose it?

Let me know if there is any particular log or config info that would be 
helpful.

On the FE/BE in question, I'm running FC5, alsa-lib-1.0.11-4.rc2, 
kernel 2.6.17-1.2174.  The BE is using ivtv-0.7.0-117.
