 Since updating mythtv from 25578 to 25612, playback of DVDs with 5.1 AC3
 sound no longer works.

 The DVD will play for a second or two then hang with copious "Waited 100ms
 for video buffers" errors.

 If the frontend is reconfigured to a plain stereo audio config, then
 playback works as expected.

 Attached are frontend -v playback,audio logs for the same DVD with both
 5.1 and stereo audio configs.

 Note: Audio is configured for AC3/DTS passthru in both cases.  I also have
 the 48k override option enabled and my patch as per #8773 to skip
 resampling of 48k sampled audio (the problem occurs without this patch as
