CM6631 usb audio interface .... any good?

[Roppu]

I'm using it with the default Windows driver. Honestly I don't know about your question

 

[790]

There is no difference between the default Windows driver and the C-Media driver, I don`t see it, but C-Media driver comes with CMUSBDACASIO64.dll

 

[Roppu]

I don't know what c-media driver you're using. Mine, provided by the dac seller, is definitely old and not the same of Windows one

 

[790]

I did not receive any drivers from the seller. I don't know who the seller is. There are thousands of sellers on Ali, communication with them is impossible. They themselves don't know what they are selling. I downloaded the driver from the Internet, all working good.

@Roppu If you wanna try my CM-driver with ASIO.dlls for Win10 32/64, this driver of 2018y, I can send it for you, ciao

 

[Roppu]

Sure @790 ! This way we can check the difference! Ciao

Thank you (spasiba?) 790.
It is unbelievable. I can't find the old drivers. I downloaded them from the link the eBay seller gave me. It is the Weilang Dac7 but I bought it some 10 years ago.
I only can find these ones on my PC and they look being for up to Win 8. And yes, your ones are much more recent as mine are ver. 7. I will test them as soon as I can plug the DAC again.
I uploaded them just for you to have a look

@Roppu Grazie Yes, I have already installed it and it does not change the definition of the device as a Speaker (Installation of program from this pack is impossible on my Win10). I know that only reflashing will help me, but this is too much of a risk for such a minor change. SPDIF-out in my CM6631A works well now for hi-res stereo and I have another device for multi-channel movies.
I know how to use SPDIFer-plugin in foobar2000 for multi-channel AC3/DTS in bitstream mode via this 6631A, but the multi-channel music that I need does not exist (I have 2 samples of Bjork in 5.1 (Dolby and DTS-96/24), if you wanna check it)

 

[Roppu]

Thank you very much 790. Though, I don't have a 5.1 system, unfortunately. Or else I'd give it a try!

烧录了您提供的固件，SPDIF 输出有 384k 样本，但没有数据。您能否提供 SPDIF 384k 工作固件？你好：

Please post in English:

Flashed the firmware you provided, SPDIF output has 384k samples, but no data. Can you provide the SPDIF 384k working firmware? Hello:

After 6 years, I built an amplifier again using a CM6631A module. I will describe some of my experiences, I think it will be useful for others as well.

-Flashtool 2.1.0.9 runs on Windows 10.

-If the fw upgrade process stops during upgrade and the CM6631A no longer works, you can still repair it using the free Zladig program, you will need to install a driver for it as a libusb-win32 device using Zladig. Flashtool can then write new firmware to the device. This happened with me once. https://zadig.akeo.ie/

Steps for successful firmware update:
-Plug-in the CM6631A, select the proper device (there can be more than one on the list, check for 0D8C... on the list), then press erase.
-Important, be sure to remove, than re-plug the CM6631A before trying to upload the new firmware.
-Select the proper USB device (there can be more than one on the list, check for 0D8C... on the list) then load your firmware.
-Re-connect after firmware update.

I uploaded the files to keep them available.
I also uploaded my own firmware file, I use it with PCM5102A DAC in 3-wire I2S mode. (for 45/49MHz crystal pair CM6631A's, 32bit / 384k mode)

hi：
Burned the firmware you provided, SPDIF output has 384k samples but no data. Can you provide a SPDIF 384k working firmware!
