"MediaPlayer audio out" claims a Latency of ''26.36 ms''.
Thanks for that. Very useful added information.
Actually that's not too bad a latency (better than I get on BeOS, anyway).
And compared to what HDA seems to work at currently (up to 300 msec delay,
apparently) it's excellent!
> Update2: one minute into the mp3 it now says ''34.48'' ms, is that
normal ? Update 3: now up to 76.89 ms, and stays so until the end of the
mp3 ?? Weird. Ok I'll let more media-savvy folks try to reproduce that
one. Note: I have a dozen "buffer late" notices in syslog [....]
Yep -- just about exactly what I'm seeing. Caused by the mysterious
'blackouts' (#7285). My revised media code I posted in that ticket
improves the media kit response to the blackouts, but doesn't help
individual apps' behaviour; if they -- as normal -- use the
B_INCREASE_LATENCY mode, they'll be affected by the blackouts in the same
way. I think the 76.89 ms is a maximum set by the program to prevent
total meltdown.

didn't know there was a problem with media-kit thread priorities!) is
addressed before coming back to this ticket.. Just in case that one
improves this one..
I find I get the glitches (blackouts) with just about any display action,
not just WP, so I don't know...
