Bug#991337: pulseaudio: Can confirm with another DAC/USB sound card

[Jean-Marie Favreau]

Dear maintainer, dear all,

It seems that the problem comes from the package libasound2-plugins from deb-
multimedia.
The following command to force the debian version of the package fixes the bug:

sudo apt install libasound2-plugins=1.2.2-2

Cheers
