In the last couple of weeks I've had a curious problem
on my Fedora-24/KDE Thinkpad T510 laptop.
Sound (on YouTube for example) starts up fine on Firefox,
but then suddenly stops working after 5 to 30 minutes.
It's exactly the same with Google Chrome.
I see nothing at all odd in journalctl -b0 ;
alsa and pulseaudio seem to start fine,
and then are no longer mentioned.
The only cure I have found is to re-boot.
I've looked at
<
https://fedoraproject.org/wiki/How_to_debug_sound_problems>
and
<
https://fedoraproject.org/wiki/How_to_troubleshoot_sound_problems>
and followed some of the suggestions there,
but to no avail.
There does not seem to have been any recent update
to alsa or pulse-audio.
I wonder if anyone else has had a similar experience?
Or if anyone can suggest any possible alternative to re-booting?
Incidentally, I can boot into Windows 10 on this laptop,
and sound seems to work perfectly there.
So it seems there is nothing wrong with the hardware.
