Do any of your customers have J River playing working via ASIO 24/96 to Turbo II?
I can get 24/96 ASIO fine in Foobar, can get 24/96 fine in J River using DirectOut, can get 16/44 fine in J River using ASIO, BUT can NOT get 24/96 in J River using ASIO.
Player indicates it's playing, and no error messages from M Audio (neither true when bit rates don't match, in which case one or the other sends error message.)
I've updated XP SP2, I've updated all drivers, and I've installed and reinstalled.
M Audio support tells me there's nothing they can do and J River says their ASIO works fine, as "proof" citing that it works on a different M Audio card.
