Hi,I ran "arecord -L" per Marcus and tried 'hw:0,0' but it didn't work. Then I tried 'pavucontrol' per Kyeong; I don't think I changed anything, but when I tried 'hw:0,0' again, it works! However, in the shuffle, the output sound which had been going to the HDMI port now goes to the USB dongle. I can always listen with headphones ;)
Also I attemped to set a symbolic link to have a permanent address. I stored: SUBSYSTEM=="usb", ATTRS{idVendor}=="0d8c", ATTRS{idProduct}=="0014", SYMLINK:="C-Media-audio" in /etc/udev/rules.d/99-usb-serial.rules but it didn't seem to have any effect. The system always assigns a link of "Device" to the dongle, but I haven't been able to use that in the 'device' field of the Audio Source.
Any thoughts? Thanks. --- Barry Duggan On 2019-07-04 02:27, Müller wrote:
Hey Barry, what I usually do is run "arecord -L" and pick one of the listed things.

So far, I have not had any success with the device name. I tried: all variations of "C-Media Electronics Inc. USB Audio Device" default (also an empty device name) sysdefault Device (there was a sym link) hw:x,y with various numbers plughw:x,y with various numbers 'PCM',x with various numbers /proc/asound/card2 (which is the correct card from the list) alsamixer shows the device as valid. There does not seem to be a 'mute' function. Any suggestions? Thanks
