I have a Turtle Beach Amigo II USB audio adapter connected to my Raspberry Pi. I have already commented out the following line in "/etc/modprobe.d/alsa-base.conf": # options snd-usb-audio index=-2 Now my USB audio adapter is first in the list when I run "aplay -l", or "aplay -L", or "cat /proc/asound/cards". However, if I run "aplay test.wav", I do not hear any sound out of the on-board audio adapter or the USB audio adapter. If I run "aplay -D sysdefault:CARD=Audio test.wav" I hear audio out of the speaker port on the USB audio adapter. How do I make the USB audio adapter the default device of ALSA? I have researched making changes to "/etc/modprobe.d/alsa-base.conf", "/etc/asound.conf", and "~/.asoundrc". However, the people suggesting the changes do not seem to understand them because they do not explain them. When I try the changes, they have no effect on my problem. ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
