Audio output voice or HiFi

Hello,

I have a hi-fi sound system but no audio player. The RPi could serve as a player. However, I would like to have hi-fi sound. To do this, it must send music via USB2 to my DAC MAgic100

How can I get the sound out via the USB port? Apparently, there is no official driver for the DAC under Linux.

Otherwise, Gladys voice does not need high-end sound. An output via Bluetooth to a connected speaker interests me. Is it planned to be able to choose the audio output according?

Thank you, the quality of this RPi DAC is very good.

However, I already have a better DAC (DAC Magic 100) and I think it’s a shame to buy 2 DACs when the maximum quality digital audio output can be sent to a single DAC. (Perhaps the RPI3B+ is limited in processing speed, but I don’t think so).

Apparently the Pi kernel supports it

I found a digital audio output of good quality:

I just need to change my case to accommodate an additional stage!

Thank you

Last question: Will it be usable with Gladys?
