cm6631 always upsamples 44K to 48K

:mad: I have one of these but it always upsamples 44K to 48K despite all settings be correct to replay 44k native rate in player, asio4all & w7 device supported rates. Tried both hqplayer & foobar (ASIO modes)

48K & 96K replay their native rates OK.

Installed driver is c-media usb2.0 high speed true hd audio 7.0.1.4

Hello Anadigit,

I sorted this by uninstalling driver w7 installed & installing driver from vendor.
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.
