Sorry, I should have said this is Windows XP, SP1.
I'll go over the connection descriptors and the filter-to-filter connections
again and see if I can see any problems. Does the checked build of portcls
or sysaudio put out any good debug info I can use? If so, I'll install a
checked build and see what happens.
I did try trimming down the descriptors to get rid of all the volume and sum
nodes and also to get rid of all but one input and output, but got the same
results.
Thank you!
