Working with sound on a Raspberry Pi

We tried to connect a microphone to the raspberry pi, for which we used:

• a mic (in a small grey bag) with a XLR connection
• a small mixer (also in a small grey/black bag) with integrated soundcard + USB connection

To test if the soundcard is picked up, we ran:

$ arecord --list-devices

And to switch soundcards, or to test/see if there is any incoming signal, we used:

$ alsamixer

and pressed F6 to select a soundcard.

Also, we selected a soundcard in the raspi-config settings:

$ sudo raspi-config

(i forgot which menu item we picked here.. 1 or 2 i think it was..)
