MQA via I2S LVDS port from SPDIF 2 - AlanHell - 11-26-2020

I recently got the SPDIF 2 to send data to multiple DACs so I can use all of them at the same time and control the music using just a single instance of foobar.
However, I am having issue send MQA enabled PCM single to the XPS devices via LVDS. (DoP to DSD=on, Revers=off, MCLK=on)
I have not changed my foobar setting, and MQA works if USB input is used on the XPS device.

Is there a way to send raw PCM data over the SPDIF 2 device?

Hi AlanHell
The X-SPDIF 2 cannot send MQA codes to DACs, if the foobar is playing MQA music, the X-SPDIF 2 will output it as lowest sampling rate to DACs.

It's impossible to let the X-SPDIF2convert MQA codes to regulat PCM signal and send it to DACs.

I have both XPS and SPDIF 2 USB connected to my PC. However, the driver only allowed one to be selected to as the USB and ASIO device. It it possible to use both of them at the same time using a single PC?

Hi AlanHell, it seems that you cannot use them at the same time.
