NAV 1/2/3/4 volume settable to 0 to 100 only using NAV_VOLUME_SET

We are not able to set NAVs volume at other values than 0 or 100 using
NAV1/2/3/4_VOLUME_SET. There’s no middle value, it sets 0 or 100 depending on
the value sent to the simvar. _INC/DEC version work. Also, the volume of the
morse codes are very low despite being at 100.

Hello @jsb This issue is already being tracked and a fix is being worked on.
