Diyinhk now has an isolated board, which looks a bit better than my hacked one ! However, it still doesn't have termination resistors between the cm6631 and the isolator. ???

Hi,
I remember reading somewhere that 176 works with the Asus firmware and their own driver, but it doesn't work with factory firmware and driver. There are sellers who will flash the firmware with either version before they ship the device.
Julcat has his working for this:

DIYINHK - what isolator IC did you choose ? Analog Devices ? Silabs ? IL ? Ti ?
cheers

Hey Regal,
I've just finished stage1 of a build using these two together - they do 176@24. however, it seems the cheaper CM6631 from this seller don't support that. I don't know exactly why - I know the driver is different, maybe the firmware is too.

No problem !
Hi,
My mistake - stupid me. It was a register setting on the wm8805 receiver.
cheers
DIYINHK - the CM6631A spdif volume has 6dB gain over CM6631 so it is distorted. The only to fix this is -6dB volume in the PC.
Can you find out if this is a firmware or driver problem please ? What can I do to fix this ? Thank you !

Hy, i've bought the board and i'm using it with windows7 foobar wasapi sox resampler and a north star 192, the board work good until 96 khz but if i set sox to 192 the dac light the correct led but there is no sound, could you help me????
Could the board work with Linus??? If yes, wich version???do i need particular driver???

Which board ? There are different ones.
I'm not aware of a Linux driver, but maybe someone else does ? Have you checked Asus' site about the Essence One ?
For the 192 issue, I'd check Windows' device settings and the ASIO bit depth driver first.
Have you tried your DAC with any other 192Khz sources ? Are you using spdif or I2S ?

If you want help, you have to do better than repeating what you wrote before hoping that's an answer. Read my my first reply to you again. I'm telling you to check your computer. You should use ASIO, not WASAPI, unless you have changed the device manager settings.
If that doesn't work, contact the seller.

If your DAC is use CM6631 it does not support 176.4 kHz I2S output. If your DAC use CM6631A it can support 176.4kHz I2S output.
Is there a 176.4 khz i2S output firmware for this chip yet ?

- CM6631 usb audio interface .... any good?
