alsa-project/alsa-lib issue #439 was opened from Starfoxfs:

I have problems with Fiio K7 USB DAC in Linux Mint Cinnamon 22.1 (6.8.0-56-generic)

Alsa Version: 1.0.25+dfsg-0ubuntu7 Pipewire: 1.0.5-1ubuntu2 Wireplumber: 0.4.17-1ubuntu4

The USB Dac has this Ports: 2x Line IN (Cinch) 2x Line OUT or Pre OUT(Cinch) 1x Digital IN TOSLINK 1x COAX/RCA IN (Yellow Cinch)

The Problem is: Alsa didnt find any of this IN Ports.

There are 4 OUTPUTS: Analog Stereo works fine with Alsa Digital IEC958 (thats wrong Device has no Digital Output) Digital Surround 51 (thats wrong Device has no Digital Output) Pro Audio works fine with Alsa

Would be nice to have the Inputs.

Heres my Alsa-Info Output:
