Command aplay -l
produce un elenco di "tutte le schede audio e dispositivi audio digitali".
Sul mio nuovissimo desktop Fujitsu Esprimo, ottengo:

Ora le mie domande:
Come mai il mio computer da ufficio ha due schede audio? Queste sono entrambe carte di bordo standard, giusto?
Qual è il significato di MID, PCH, HDMI?
Quale è collegato alla spina standard verde muschio?
