Some problems solved
Using the keyboard P8-P9 or “+” and “-” it’s possible to adjust the volume. Also in the Volume settings the volume and the amplfier volume must be set to 100%.
I don’t understand the ActionA reply. I have installed the OSMC and not XBMC, .Could you pls clarify thanks.

XBMC is now known as Kodi. OSMC provides Kodi for your use. AFAIK, the key map had not changed so I provided it for you to reference for finding volume control.
