Hi, Here are some of the description of the IC CM6631 from cmedia, I want to upload the datasheet, but it is a bit large with 16 pages and failed to upload here, if someone intrested in it, you can search on google or PM me, I can send to your email box. This is a great IC!

"Cmedia CM6631 is the world’s first USB2.0 true high-speed audio processor that can support the latest USB Audio Device Class Definition V2.0 and high-definition audio processing capability up to 192KHz/32bit. CM6631 provides the industrial standard I2S and HDA audio interface and also integrates 192KHz/24bit S/PDIF transmitter/receiver and MIDI I/O device. It’s suitable for versatile, high-profile, typical 2-channel I/O audio applications. Furthermore, CM6631 has an embedded 8051 microprocessor that can enhance the best flexibility and functionality with external upgradeable F/W codes. CM6631 would be the most high-fidelity and powerful audio core for high-value USB2.0 audio products. "

I was asking about DSD not DTS, they are very different things. I haven't seen any device based on the CM6631 claim DSD compatibility but I don't know if they have just too lazy to include it in the drivers or it is the chip that doesn't support it. C-Media aren not the best when it comes to writing drivers.

I can not get the ASIO driver to work in J.River using Win7 64 bit OS
http://jriver.com/
J.River will just locked up when selecting USB CM6631 ASIO for the output.

Windows Direct Sound works fine.
ASIO does works on my computer sing the M-Audio sound card and the Juli@ professional card ASIO drivers as well

Is there a way to make J.River to use the ASIO driver for the CM6631 with J.River?
What audio playback programs work with the ASIO driver?
