Sorry, I had not. I just did with svn rev 15806.
With the mythtv_ac3.48.patch timestretch is complete unusable. As
soon as I hit the "TOGGLESTRETCH" key (ctrl-s on my system), all I get
are clicks and pops -- the audio completely goes away. Toggling the
timestretch to go back to 1.0x speed does not fix the problem -- The
only way to get the audio back is to stop the show and start playing
it again.
