Re: [LUG] External speakers no sound

Common problem. Audio control has a number of ways to switch off or on
the same device. You need to start by re-booting without your ear plugs
in machine. Then check all audio settings and ensure they are switched
to on and also check your browser that you did not 'switch off' a video
or YouTube in its tab sound icon (not in audio settings!) before closing
down previous time. (This can be  a%%%$%! to find)

Yes, I do know what a pain this can be. I have looked around a bit, and can't see any problems. Looking at Volume Control under the Multimedia choice in the menu, it does show "Headphones (plugged in)" under Output Devices. When I unplug the phones, the message changes to "HDMI/Display Port (plugged in)".
Under Configuration there is a long list of "Profiles". Most of them are 
marked as Unplugged. Of the others, only two give any sound, via the 
headphones. These are Analogue Stereo Duplex and Analogue Stereo Output. 
The others, even if not marked as unplugged, don't work.
What puzzles me most is that it all worked on Friday. I did absolutely 
nothing with the sound system at all (well yes, as normal, I did run one 
or two Youtube videos) and it was all working just fine. Yet on Saturday 
when I logged in there was no sound from my external speakers. (My 
screen does not have any inbuilt speakers.) So I tried my phones and 
they worked straight away.
What a pain,

Neil
