--- Comment #17 from Greg V <greg@unrelenting.technology> ---
I'm seeing a similar-but-not-really issue on my aarch64 box (MACCHIATObin).
After watching YouTube for some minutes, with an old ASUS Xonar uaudio0
(recognized as "C-Media Electronics Inc. USB Advanced Audio Device"), sudde=
nly
for a couple seconds the audio starts crackling and muting, and then stops,=
 and
in a few seconds USB input (!) stops working. Specifically USB mouse and
keyboard. USB Ethernet keeps working fine. I can even start playing music o=
ver
SSH, headphones are silent but the progress bar keeps going. I can unplug t=
he
audio card and it detaches fine. But USB input is dead, even after `usbconf=
ig
reset` there are no events on libinput, no input on the vt console either.
