[mythtv-users] blank screen + "Audio buffer overflow, audio data lost!"

Yeah, I know, I just didn't want to belabor the point on list when it was
probably not relavant to the problem... or at least I thought so. Are you
saying theres something about Fedora that is actually causing problems? I
had assumed it was just that I had managed to screw up a setting somewhere
in the process of upgrading... you don't mean to say that you actually saw
*this particular* problem on Fedora .93 do you?

It doesn't seem to make much sense to me that Fedora could be at fault,
since I built all of myth's requirements from source this time around,
(excpet ALSA, which is still installed from the same RPMs which were working
before), <dont really know what I'm talking about, just BSing>so unless
fedora's gcc or glibc are screwey, I can't see what code from the
distribution would even be involved.</dont really know what I'm talking
about, just BSing>

Can anyone tell me what the "Audio buffer overflow" error actually
signifies? Is it generated by myth or by ALSA? Would a backtrace provide any
meaningful info? And if so, frontend or backend?

i.e. NOT Red Hat beta. It is Fedora Core Test, v0.94, pre-Fedora Core
1. But I understand what you're saying. For the record, after Red Hat
Linux 9, there is no Red Hat Linux, only Red Hat Enterprise Linux and
Fedora (sponsored by Red Hat).

No idea. MythTV didn't like the first Severn release either. I have yet
to dig into it and/or try on the latest release. Look in
/var/log/messages and your mythbackend log for more clues. I'll
probably give FC 0.94 a try in the near future myself...
