Title:
Keys stuck on repeat when key triggers sound, and output device is
ClearOne Chat 50
Status in gnome-shell package in Ubuntu:

Bug description:
When I am typing in a gnome terminal, any time I press a key that
triggers a sound (e.g., hitting "backspace" when already at the
beginning of the command line, hitting "tab" for tab completion when
there are multiple possible completion options), the key gets stuck on
repeat. The sound plays over and over. If I move the mouse to other
windows and focus on them, the repeated key continues there. (I have
focus-follows-mouse enabled, if that matters.)
This is 100% reproducible. But I have tracked it down to only occuring
when I go into Settings->Sounds, select the "Output" tab, and choose
the "Analog Output - Chat 50" device for sound output.
I do have a ClearOne Chat 50 plugged into my computer via USB. It
seems to be operating correctly for both input and output sound
(ignoring the key repeat issue).
Before figuring out that changing the sound output to be something
other than the Chat 50, I ruled out the keyboard being the problem by
swapping in a different model of USB keyboard. I also rebooted the
system, and that made no difference either.
I saw other bugs about repeating keys, such as bug #124406. I did try
disabling repeat with "xset r off". This seems to stop the repeated
key from taking effect in, say, Gnome terminal. But the repeating key
is probably still being issued somewhere in the system because when I
then trigger the bug the keyboard becomes unusable until I unplug it
and plug it back in again.
In all cases, unplugging the USB keyboard and plugging it back in
again eliminates the stuck repeating key.
I apologize for not selecting a particular package for this bug. This
bug does only seem to occur when the ClearOne Chat 50 is selected as
the output sound device, but I'm completely unclear about how an
output sound device could case key presses to operate incorrectly. I
does not seem like the sound device should be able to cause a keypress
to repeat even if the sound driver is buggy.
