i updated my laptop to Ubuntu 20.04.1 LTS with XFCE4 last year. Since then I’ve had the following problem:
after booting the machine the speakers function correctly – i can skype, listen to films, etc.
However if i plug in a pair of headphones and then unplug them again, the speakers stop working until after the next reboot.
Does anyone have an idea where the problem might beß
Thanks in advance,
