No sound on Linux ... and how to fix it.

[louis-barman]

I am running Ubuntu 20.04.2 LTS and there is no sound when using fluidsynth on a fresh install.

I fixed this by editing fluidsynthplayer.py line 16 which I changed from self.fs.start() to self.fs.start('pulseaudio')

This is obviously not the correct solution for other OS's but it worked for me as no default output driver was being set. I am not sure where the default output driver should be set.

By the way the prefered audio driver on Ubuntu should be pulseaudio rather than alsa because if alsa is used it locks the sound output and then no other apps can use the sound output.

I hope that is useful to others who have the same problem.

The default sound driver for FluidSynth is now pulseaudio if OS is Linux.
