While I do not have the same USB soundcard this bug started with, I can confirm this is still happening with the 5.5 Kernel running in Ubuntu 19.10 and other USB sound cards. I am using a Schiit Fulla v3. When trying to use ALSA mixer I get the same broken pipe error. When tailing both journalctl and syslog I see the following error when the broken pipe occurs.
