Korg Triton demo error: 'no pcm' no sound, but gui works fine

[4duhwinnn]

All other plugins working, in Triton, everything seems working,
gui resizing(!!!), browser, instrument controls, virtual keyboard etc,
just no sound coming out. Likewise the standalone .exe.
Demo times out after 20 minutes, and no saving in the demo
Also, the prefs menu is buggy, with poor font display,

Using wine-staging 5.8, Reaper 5.99 Ubuntu Studio 19.10

Same error and functionality in both linux-reaper with LinVst,
and windows-reaper in wine, with wineasio.
Changing winecfg settings between 7, 8.1, 10, and global
doesn't fix it.

Perhaps more hits were backed by Tritons, than any other keyboard,
and there is a massive dose of sounds in the browser
just itching to vibrate.
(But then there is Korgs flaky reg engine to deal with,
claiming it can't find the internet you just got their product with...)
Cheers
