Title:
USB audio device is not recognized after startup in 16.04
Status in alsa-driver package in Ubuntu:
Invalid
Status in fwupd package in Ubuntu:
Confirmed
Bug description:
Hi @all,
I used the same USB audio device in all previous Ubuntu versions
(Focusrite Scarlet 2i2). It is supposed to be class compliant and
works an all distros flawless (even RPI2 and OSMC). After upgrading
from 15.10 to 16.04 it stopped to work: after start-up it does not
show up as an audio device at all (also not recognized by aplay -l). I
can workaround this by unplugging it and plugging it in again after
Ubuntu booted up (strangely 2 times unplug/re-plug). After 2nd time
plugging it in again it shows up and works great without any further
issues until next restart.
Maybe worth to note that I recognized today that fwupd uses
continuously 100% CPU load, so I just killed it today. My Hardware
(Main-board/CPU) is a bit older (Intel E8400), so could probably be
some compatibility issue...
regards,
Tobias
