No sound from internal speakers after using HDMI output
I fixed with this
$ rm -rf /tmp/pulse* ~/.pulse* ~/.config/pulse
$ pulseaudio -k
$ pulseaudio --start
I had the same problem, here is how to allow internal sound after using HDMI output - this worked for me.
In the hidden cache folder in your home directory, there will be a file called something like event-sound-cache.tdb.641c9db826a44f28bb9596d6df3020c2.x86_64-pc-linux-gnu
. Just find the file and remove it. Now, your internal sound should work.
In a terminal, from home directory:
cd .cache
ls -a
Now look for the file starting with event-sound-cache.tdb
.
For me, it was
event-sound-cache.tdb.641c9db826a44f28bb9596d6df3020c2.x86_64-pc-linux-gnu
Now, in the terminal, type:
rm <file name here>
For me, my input looked like this:
rm event-sound-cache.tdb.641c9db826a44f28bb9596d6df3020c2.x86_64-pc-linux-gnu
Note that the event-sound-cache.tdb
file with be unique to your machine-id and OS.
Your internal sound should now work. If the sound still does not work, go to the sound application and re-select Speakers (Built-in Audio) as the option for sound.
