I guess the second audio device is either HDMI or HD audio generic. You |
41 |
could verify this by opening alsamixer then select F6 to see a list of |
42 |
audio devices. If you use pulseaudio then you can select the default |
43 |
output device. Or use /etc/asound.conf to select your preferred default |
44 |
device. |
