Micromega DAC

Good evening,

I have a USB DAC from Micromega: a "MyDAC".

It used to work flawlessly using both ALSA & PulseAudio. But since a month or two, I have these problems preventing it to emit any sound:

- in dmesg, I have :

usb 1-2.1.3: Product: MICROMEGA MYDAC

The last line keeps repeating.

- When I use alsamixer to select it, alsamixer exits and I have this error message: the mixer commands can not be loaded: invalid argument (translated from French, sorry).

Yeah it's me again with my custom compiled kernels. You bet I have a compilation option missing somewhere?

I currently use the 5.18.12 kernel and I'm sure the DAC works since it provides sound from Windows, with the same USB cable.

Thanks for any help guys.

Regards,

Zala GOUPIL
