I am using a Toshiba Tecra and I had Ubuntu 18.04 LTS installed, and I just upgraded to 20.04.
Most things work fine, I have sound in general (youtube videos play) but my terminal bell stopped working after the upgrade.
Normally, nano gives a “ding” noise when a file is not writable, and it stopped doing that. Emacs and vim also don’t make noise anymore, like when I try to scroll past the beginning or ending of a buffer.
Bash does not make noise upon tab completion. I tried:
sudo vi /etc/inputrc
set bell-style visible
which I thought would cause the screen to flash, but it does not.
I tried the command:
echo -e ‘/a’
and the command:
both of which should give a terminal bell sound, and neither did.
I also tried editing the modprobe file:
sudo vi /etc/modprobe.d/blacklist.conf
and commented out the line:
but this did not help.
When I open up my terminal preferences, I see that
sound: terminal bell is checked.
Not sure what else to try.
