Имеется встроенная звуковая, внешняя Audiotrack Prodigy HD2 и звук по HDMI с видеокарты:

Отправляю звук на внешнюю звуковую:
aplay -D plughw:1,0 /usr/share/sounds/alsa/Front_Center.wav
aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav
И еще вопрос - как отрубить звук с видео-карты по HDMI который видно как NVidia [HDA NVidia]? Заблэклистить не выйдет т.к. он виден как HDA-Intel. Т.е. так же, как и встроенная:
cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xe3400000 irq 48
1 [ICE1724 ]: ICE1724 - ICEnsemble ICE1724
ICEnsemble ICE1724 at 0xb080, irq 18
2 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xe3080000 irq 17
