Comment (by Josh Triplett <josh@…>):

 > So please provide details.. Audio settings, version of myth used,
 computer used.

 Audio settings: ALSA:default and the stock MythTV defaults.  I've tested
 with a completely fresh set of client settings and still encountered the

 MythTV 0.25.

 Client: ThinkPad X220, ThinkPad T42, custom frontend with an Intel
 D945GSEJT Atom board, take your pick.  They all have some variation of an
 Intel HDA audio chipset.

 > I certainly have never seen this on any of my machines, and you would
 think that if it was a global issue, we would have heard about it.

 This represents a subtle issue; if you didn't otherwise have reason to pay
 close attention to the audio, you could easily not notice it.  You'll
 notice it more easily if it takes your setup a longer time to seek, pause,
 or unpause.  Effectively, the video starts changing immediately, but the
 audio doesn't switch over until after the video finishes changing.  So,
 however long it takes to seek, the audio that would have played if you
 hadn't seeked will play while you seek.  In former versions of MythTV, the
 audio would instead immediately stop playing while the operation happened,
 and start back up again with the correct audio after the operation

 > I doubt you are running the same hardware/OS as you did when you were
 using 0.22

 Exactly the same hardware; OS upgraded from Debian 5 to Debian 6.
