[AG-TECH] Audio freezes on WinXP x64 with RealTek AC97

We have the SoundBlaster Live! Card installed in our node now for a few
months since the on-board Sigmatel HD audio would not play well with
rat.  The USB card works well, however we did fry it during the first
meeting.  Creative replaced it and I have not had any problems since.

On a side note, if anyone knows of any progress in terms of Rat and HD
audio, I would be all ears.

Thanks,

For what it's worth I'll reply to myself on this:

I've downloaded the Sumover rat code from
   http://mediatools.cs.ucl.ac.uk/nets/mmedia/wiki/SvnDev
and compiled eveything using Visual Studio 8. One thing fails -
the ratui link gets errors because the tk library contains X
functions. Rather than spend any more time I replaced the the AG
executables: rat.exe and ratmedia.exe, with the newly compiled
versions. 

The result is that the same problem exists - rat still freezes
after a bit of time, it may however, be a bit better, but my
perception is probably just colored by putting some time into
the build.

Would anyone have experience with external (USB or firewire) sound
cards on 64-bit Windows? I see that the Creative SoundBlaster Live! 
24-bit External has 64-bit drivers and for about $50 it might be
worth a try.

Jon.

I'm trying to get AG working on a 64 bit Windows XP system. The 64
windows drivers for the USB cameras (Creative and Logitech) I'm using
are working great. My only problem is with the audio - PCI cards
have given me nothing but grief. The onboard audio does work 
briefly, but after about a minute rat freezes. I can restart rat
and it will work again for a short time. Would anyone have a new
build of the Sumover rat that I can just drop in to replace the
existing rat for AG 3.0.2 (build 1)? A 32 bit build should be just
fine.

Thanks,
Jon.
