Hello,
I want to build my own USB soundcard for Windows 10 with at least 384kHz/32 bit DAC, like PCM5102 or similar, and for at least 192kHz/24 bit ADC.
Now I have XMOS interface, which only supports output. I like XMOS, it sounds good, it has no noise, it works well with Windows 10, which I am using. But the problem is, that it has no input.
I have module with WM8782 ADC, which is 192kHz/24 bit ADC with I2S output. I don't know how to connect it to my computer. I was searching, I found interface CM6631, but I didn't found any module, which has wired input interface. Only output one. I also found that some guys overclocked it's output to 384kHz/32 bit, but I didn't found any modules or projects, that uses input and output interface. Do you know any? How can I use CM6631 as input?
Second chip I found is CM6635, which supports I2S input and output at 768kHz/32 bit, but I didn't found any datasheet or projects with it. Do you have any informations about this chip?
Thanks.

I can't tell about CM6631/5 but if you are looking for ready modules, I have good experience with this XMOS Multichannel high-quality USB to/from I2S/DSD SPDIF PCB - DIYINHK and there is also this one MCHStreamer - USB Audio Swiss-Army knife - Multichannel PCM/DSD/PDM/ADAT/TDM/SPDIF interface but I haven't use it.
Hello,
thank you, I am looking at XMOS Multichannel, it looks good. So if I understand correctly, you can connect this module to your computer, it'll recognize it as speaker output and microphone input?

I would recommend the MCHStreamer over the DIYINHK. Bth are xmos based, but the minidsp offering is from a well used manufacturer that finds its place in numbers of OEM products. the same cannot be said for the DIYINHK offering. neither are top shelf designs, but the minidsp stuff (particularly their more recent products) is far more competent IMO.
I have and use their 2x4HD DSP and USB module. its been pretty solid.I used it directly for a while; with good success, the software is pretty good. i'm using its i2s out with external dacs, which was always my plan; not because I found it lacking after buying it.
I have also found this module XMOS 32Bit 384kHz DXD DSD256 USB to/from I2S, to DSD/reclock SPDIF PCB - DIYINHK which is cheaper. Will it work also like regular soundcard?
From what I gather it takes both DAC and ADC I2S PCM up to 384kHz/32bit but then it says it outputs only 32bit regardless the input. Does this apply only to the DAC? Can it support your 24bit ADC? I suggest you better ask them to be sure.
