Raman--

Yeah, I chased my tail for a bit today trying to get the PCM buffer to zero 
out 
half of it, seems like legit OS bug in MacOS, reaching out for more help, but 
I have it reduced to a minimal example and still no luck. To double my 
annoyance it works fine in the old version (NSS variant) which will be removed
in MacOS 15. MacOS is a second class citizen in AVFoundation support.

That said, I might have found a solution, it would require a little setup by 
the 
user but you can create new composite device on MacOS and you can 
reduce the volume to 0 on the right or left channel. Trying to see if I can 
do 
this setup programmatically and confirm I can target that device for output, 
but 
it is at least a path (got the idea from the emacspeaks code). 

But enough zero progress for tonight, more zero progress tomorrow!
