STFW I found some information that might be useful.


Here is the chip makers web site:

https://www.cmedia.com.tw/EN/index.html


It looks like two versions of the chip are currently made:

https://www.cmedia.com.tw/products/USB20_FULL_SPEED/CM108AH

https://www.cmedia.com.tw/products/USB20_FULL_SPEED/CM108B


This link indicates that some version of the chip worked on some Linux 
machines at some point in time:

https://linux-hardware.org/index.php?id=usb:0d8c-013c


More links:

http://www.linux-usb.org/USB-guide/x319.html

https://linux-hardware.org/index.php?id=usb:0d8c-013c


There are several links for people with Raspberry Pi boards running 
Raspian.  They made changes to their ALSA configuration to use a CM108 
USB audio interface.  I don't know if those instructions apply to Debian.


Please run the following commands, and cut and past the commands and 
their outputs into a reply:

cat /etc/debian_version

uname -a

dmesg | grep -i cm108 -A 10 -B 10
