Descent has no sound and mice

[Kppot]

Hello everyone,
I have some troubles running Descent (from Parallax Software) on my A1200 060
It runs okay has decent framerates but:
1. It has no sound (or music)
2. It has no mice support, ie as soon as I run the tool, there is no mice, I need to pick up screen resolution by using cursor keys.
I tried ingame (!) sound volume and mice support, no results. Soon I discovered that Icon (tool) properties have some specific to Descent options and there are
(NOMOUSE)
(NOSOUND)
I deleted them but no success, no mice and no sound.
It is ok with sound, but having no mice with Descend is a hard time
Here is like my tool looks like

And here is ingame option, mice cannot be chosen

I do not believe it is smth with Descent itself, I simply cannot do tool properties right way. I am changing tool props with no result.
I am using Christian Sauer port, but Descent Rebirth has the same problem (it also has NOMICE option within the tool)
