use a hifiberry soundcard with your linux pc

Hi,

I tried to use the REW generator to stimulate a hifiberry board and had the problem to send the produced sound to the hifiberry. Copying files was quickly boring.

This might help win/osx users:

On a Debian 11 system (pulseaudio 14) I was able to do:

sudo apt install pulseaudio-module-raop
pacmd load-module module-raop-discover
pacmd list-sinks

With some wild clicking in pavucontrol and REW I was able to hear the generated tone!

In REW I had to select the Output device "default [default]" and not the "Default device" for reason unknown.
