I am using a Focusrite Scarlett 2i2 USB audio interface, and am having a number of issues that I did not have in older version of ubuntu (these issues started occuring sometime in 19.04-19.10, can't remember which). I am having three major issues. Number one is, if USB autosuspend is enabled, it will stop working completely until reboot after anywhere from a few minutes to several hours. Reconnecting the device does not fix it and it seems to not power on at all, with dmesg reporting a "usb_set_interface failed -110" error. Sometimes this bug can be recreated by manually disconnecting and reconnecting the device, however I was unable to replicate it in this manner at the time of filing the bug. Another (presumably related) issue I am having is that if I reconnect the device and it doesn't fail, it outputs very crackly audio, as if the bitrate or sample rate were set incorrectly. This persists until a restart of pulseaudio. Previously, I had a similar bug where it would randomly start doing the crackly audio thing until reconnecting the device and in this case a restart of pulse did *not* fix the problem. I am unsure if this issue still happens as it was fairly rare. The third problem is that sometimes when performing a suspend/wake cycle, the interface will power cycle several times, in intervals of 15-30 seconds or so before staying on properly. As previously mentioned, these issues are fairly new and did not occur in older versions of ubuntu. I have confirmed that the audio interface works fine under windows.
