Fiio M3K: Failed to find a working profile

Fiio M3K: Failed to find a working profile

[GitHub issues - opened]

alsa-project/alsa-lib issue #123 was opened from x1unix:

Hello, I have a [Fiio M3K](https://fiio.com/m3k) player which I often use as an external USB DAC.

It worked well with Pipewire, but I had some other issues with Pipewire so I had to rollback to PulseAudio.
Unfortunately, PulseAudio and module-alsa-card cannot setup this device, so it doesn't work.

Here is a small portion of PulseAudio log (full log is available at link below):

```

```

I'm using ArchLinux and Linux 5.11.2.
