Game freezing & audio issues

Hi,
I experience the following two issues when mapping:

Game freezing - Usually once per map. The game freezes (but does not crash). I have to manually stop and restart the game. When I am back on my map, the fog of war is also back (like I never was in the map)

Audio issues - Usually the whole time when mapping. Audio is double, cracking, distorted. Sometime it simply dies altogether.

Both issues seem to occur more often in crowded maps, especially in CPU heavy moments. Since I am playing zealots in juiced T15 maps this is quite often the case for me.

As the game does not crash I can not submit crash reports using console crash handler.
