Jack Keane 2 starts with no sounds in game (music, speech, effects).

All other games working fine (including JK1). My audio settings in windows are set to the correct output-device. The JK2 channel in mixer is shown if the game was started and shown in the correct audio mixer device. In game all audio volumes are on.

Running with GoG on Windows 10 Pro - 21H2.

Anyone here with the same problem and found a solution?

ok, found the problem.

Solution was to quit "Sonic Studio 3" from ASUS.. then everything seems to work fine.
