I lose audio after rebooting my computer. It comes back if I remove
my speaker cable from the jack ( in the computer, not the monitor )
and reinsert it.
Post the output of the following commands:
# list available and default audio output (pseudo)devices
LANG=C pactl list short sources 2>&1 | grep output
echo
LANG=C pactl info | grep -e '^Default Sink'| sed 's@\(.\{60\}\).*@\1@'
# Is the default output device the one you think it is?
# check the volume of the default audio output device; is it muted?
env LANG=C pactl list sinks | awk '/^Sink/||/Volume:/'
Depending on what the output of the above commands is you may need to (re)define the default audio output device and/or change its volume setting.
# select default audio device
env LANG=C pactl list short sinks 2>&1 | grep output | sed 's@\(.\{60\}\).*@\1@'
read -p "Select default output device: " # enter the index number
[ ! -z "$REPLY" ] && pacmd set-default-sink "$REPLY"
# change volume setting
PA_sink='<some (pseudo)device from the list above>' # full name, not just the index number
env LANG=C pactl set-sink-volume $PA_sink 70%
If the problem is gone, insert the appropriate commands in some
user/terminal session startup file.
