Just want to add my 2 cents for the archives. I switched the mlayer
launch string to use oss and my sync issues went away.

Thanks Axel for the quick response.
It is certainly puzzling, and I only just noticed it the other
day, it
could have started happening when I updated on May 28, though I'm not
certain. The old alsa I had been using was 1.0.8, but its wierd in
that only xvid/avi is affected, and I'm using mplayer within and
outside of mythtv with identical results, though it looks like
mplayer
hasn't been updated for quite a while. Nothing in the diff's stick
out like a sore thumb. When I get the chance, I'll think about
switching back to alsa 1.0.8 and report back....
Or you can use mplayer with oss to verify it's the alsa libs. Also
what CPU load do you have during playback?
If you find that this is a bug in alsa, please report to
https://bugtrack.alsa-project.org/, thanks!
Thanks again,
Adam

Yes this is exactly the problem, and its been easily corrected
for me
with the -delay option. I also noticed it happened after an
'apt-get
dist-upgrade' and I'm pretty sure alsa was updated then (as well as
most mythtv packages). The alsa rpms I'm running must be:
alsa-kmdl-2.6.10-1.770_14.rhfc3.at-1.0.9rf-39.rhfc3.at
alsa-driver-1.0.9rf-39.rhfc3.at and alsa-utils-1.0.9rf-14.rhfc3.at
alsa-lib-1.0.9rf-21.rhfc3.at
libasound2-1.0.9rf-21.rhfc3.at
which look like the current versions on atrpms. i'm not
entirely sure
what the old versions were, but it had been at least 2 weeks or so
since the last dist-upgrade. I haven't looked at the atrpms
list, but
i'm cc'ing this message to that list in the hopes that the right
people notice this and may be able to comment if it is an rpm
problem
or not.
FWIW, my mainboard is
SOYO SY-P4RC350 Socket 478 ATI 9100IGP (RS300) Micro ATX Intel
Motherboard
with onboard sound
ATI Technologies Inc IXP150 AC'97 Audio Controller
Thanks,
Adam
ps. is there a simple way to list the previously installed alsa
packages or downgrade? my mind is failing me right now...
Try
rpm -qa --qf '%{name}-%{version}-%{release}.%{arch}.rpm\n' 2>&1 |
sort > /tmp/rpmpkgs
ls -ltrA /var/log/rpmpkgs* /tmp/rpmpkgs
diff -ud /var/log/rpmpkgs /tmp/rpmpkgs
etc.
But I can't imagine alsa delaying sound. It has to be an issue with
the client application. Perhaps the ABI changed in an incompatible
way?
FWIW I don't see (well, hear) any such delays.

I had the exact same problem last week after updating from at-
rpms. A
number of packages were updated but I noticed that alsa was one
of them
so maybe it's the cause? It seems that only divx/xvid files are
the
problem though. No problems with any other formats so far.
I haven't had any luck tracking the problem down but I may
downgrade
alsa and see what effect that has. Has your alsa recently been
updated?
If so what were the previous and current versions?

Hey folks,
Maybe I'm hallucinating (it is entirely possible), but
suddenly when I
am watching videos using mplayer in 'watch videos' my audio is
out of
sync with the video. If I manually adjust to +0.275s by adding
'-delay 0.275' to the mplayer command line, it looks better.
This
only seems to happen with videos played using mplayer (xvid
avis in
particular), but when I watch recorded videos (from pvr 250)
they are
fine. This only started happening in the last few days,
before this,
videos which have the mismatch worked fine. I'm just curious if
anyone else has seen this recently. I've got a FC3 setup using
ATRPMS.
Thanks,
Adam
