Hi,
I have a problem (described below) that is absent on a kernel that I
compiled myself. Is there some (USB) audio diff in snapshots that
could cause this? Otherwise, there may be something wrong with my
testing.
The problem starts when I press the volume-up or volume-down button on
my uaudio(4) headset (once or a couple of times). These are the
symptoms:
* When watching systat -s 1, ehci0 shows 50 interrupts per second
(that's still normal). When I press one of the physical volume buttons
on the headset [a couple of times], it jumps to +/- 480 interrupts
per second.
* xterm behaves normally (it processes my keystrokes as usual) but
providing keyboard or mouse input to Firefox becomes problematic;
it takes a very long time before they are processed by Firefox.
* In the mpv program, pressing the volume-down button on my headset
causes the volume to go down to 0, as if the button was pressed
continiously. And the volume goes up to 130 when I press the volume-up
button. When I press the 'Alt' key, mpv logs the following to the
console repeatedly:
[input] No key binding found for key 'Alt+VOLUME_DOWN'.
>From the last point, it appears that somehow once I press the
volume-down button, it appears to the computer that the button is
pressed continiously (which is not the case).
Those problems (the high number of interrupts, the "key pressing")
go away immediately if I unplug the USB dongle that connects my
headset to this machine. And if I plug it back in again,
the problems stay away until I press the volume buttons again.
Also, those problems do not appear on a Linux box that I used to test
(to rule out issues with the headset itself).
