Just to add, I also have this problem

I've tried MythMusic .8 and CVS

Running RedHat 9 with a Duron 1.2Ghz 512mb Ram 60gb total hdd space

I've not tried Org or Mp3's just CD audio

@ exactly 4 seconds into playing of a cd I get the exact problem as Vince.

Hello,

Thor, just hoping you'll read this. I didn't hear back from you after
my previous message in this thread (quoted below) and was just
wondering if you had any other ideas to rectify this problem (or to try
tracking it down). I just compiled the most recent CVS version and yes,
the problem is still there. To refresh your memory, mythmusic is
freezing while playing. The music continues, the interface stops.
Tested using OSS and ALSA.

Thanks,

Vince

Hi,

I just installed MythMusic last week and and having the same GUI hang
problems when playing MP3 or OGG that others are seeing. I'm also using
RH9 with a SB Live and version 0.8 of the software.

I've rebuilt with symbols and fired up ddd, it seems to be hanging in
MainVisual::timeout() trying to get a lock.

Here is the thread and backtrace info that was asked for earlier:

I put some cout before and after the lock and unlocks. It gets the
lock and can free it fine for the first 5 seconds or so, and then it
starts hanging.

I've worked around this by changing the first set of mutex calls in
MainVisual::timeout() from output()->mutex()->lock(); to
mutex()->lock(); I'm not sure what the side effects of that are, but
the playback GUI seems to be working now.

Does anyone know what else competes with that resource for the mutex?
I'm not quite sure how to proceed from here.

Thanks,

-Tom

Mind trying to reproduce with current CVS? Or, does the problem still exist
with the removal of that output()->mutex()->lock()/unlock() pair?

Hi,

I modified the .8 version before, when I delete the lock/unlock pair or
change it to just mutex()->lock() like the calls later in the function,
everything starts working. I don't know what the impact of that change is
though.

I've tried the CVS version, but I can't get it to playback, the top row of
controls (PB, FF, RW) don't seem to work. I'll try to get that going, maybe I
don't have it set up correctly.

-Tom
