I am using the following commands to have mono sound output in Ubuntu 16.04:
Find output device name:
pacmd list-sinks | grep name:
Get mono output:
pactl load-module module-remap-sink sink_name=mono master=THE_NAME_FROM_THE_PREVIOUS_COMMAND channels=2 channel_map=mono,mono
The problem is that even at full volume the audio is too low.
Can someone please point out how to solve this issue?
