Coffee is much better. Don't add any impurities though (milk, sugar

I'm was actually using both whisky AND coffe w milk. Sorry, no

After some serious fights w the build system, I've been able to add a
simple PTRACE to the SetBuffers method in sound_alsa.cxx. Trimmed
output:
13:45:49.348 ALSA Setting buffers, size: 3840, count: 5
13:45:49.402 ALSA Device default Opened
13:45:49.438 ALSA Setting buffers, size: 320, count: 5
It is set in opal in
OpalAudioMediaStream::OpalAudioMediaStream(
where soundChannelBuffers is set to the supplied parameter value.
This comes out of the pcssendpoint class, which
which ends up coming from: a method of the pcss endpoint which gets
the user defined buffer depth...
soundChannelBuffers = pcss endpoint.GetSoundChannelBufferDepth()
so you know what ?
I think this is a bug from outside of ptlib&opal. The default values
for codec sizes in ptlib&opal are for a count of 2 buffers (unix) and
3 buffers(windows).
Derek.
Indeed. I have submitted a temporary patch to
http://bugzilla.gnome.org/show_bug.cgi?id=572953. Not tested, but
should be better than today. If it not makes other problems
visible...Many thanks for your help with his, I wouldn't really have a
chance without it.
