I use audio via ear buds for phone calls on my laptop.
As part of my routine, I hibernate my laptop (fedora 30) nightly. So every
morning I unplug and plug back in my ear buds. Nothing else I do has the same
effect. If I do not do this the audio out level is low, and no CLI approach to fix
this worked for me.
Eventually I may wear out the jack, and it is "just one more thing" I have to
do daily. Is there a programatic way to get the same effect?
Also, I have to go into pavucontrol to manually change the system to use the
headset microphone.
Finally I run a bash function '_sr' ( as in "sound reset" / see after my sig ) to unmute, and
ensure that the levels for headphone mic and output are correct. I'm sure that
the '_sr()' needs fixup, but it does help me.
Any constructive tips appreciated!
