It will be the perfect external USB sound card for my laptop to run my DIY sdr station.

24bit/192Khz line I/O to decode the I/Q signal is a must and I'm convinced there are 1000 out there looking for a such board.

I now have 4 of these units & they are all fine (3 with 88k & 176k firmware).

Always you have to uninstall driver w7 installs & use vendor driver, this is weakness in w7 (XP gives you option to install from location of your choice, which is what you want !).

Also you have to open device properties and tick sample rates supported.

Also if you use different usb socket you need to install drivers again.

I installed the new CM6631 board today. Loaded the drivers and it plays great. I desoldered the LED and hooked up the wires to the case USB LED.

I can't figure out the LED though. The old USB board only lit the LED when the computer was plugged in. This one comes on at power up. Is there a second spot to wire in the case USB LED? If there is I can't find it.

Hi Mr. Weiliang.
I have bought 2 DAC7 with CM6631 USB modules fom minishow seller (user RAZOR2000SHOP). These units work fine but I have a problem with CM6631 when I try to play wave file in 192khz 24 bits resolution. The sound is good but I have also several scratches noise (non periodic). I'm using a TOSHIBA TECRA pc with WINDOWS7 but the problem is existing also with other computers.
Someone told me that is necessary a new firmware. If this is true could yuo send me the firmware, the installation tool (for WIN7) and the instructions how to do it?
My emai is: roberto.marin@mail.wind.it
Thank you in advance.
R. Marin.
