[mythtv-users] rebuffering and ringing sound

[Mark Chou]

Occasionally I get very high pitched ringing in my recordings (it sounds 
as if speakers might have screws loose, similar high pitched buzz).  I 
suspect that this is caused by internal (system) delays, but it 
inevitably happens immediately subsequent a "Rebuffering" message (in 
frontend while watching live tv).  Once the ringing starts  the only way 
to stop it is to restart recording/or live tv.  Obviously during 
recording restarting is not much of an option (even if you're aware the 
ringing has started.)

Any suggestions how this might be mitigated?  This problem has been 
around from mythtv 0.8 to the latest cvs (6/3).
