I think the same way as chip does! First of all, the patch really is a fantastic improvement, and I am really grateful to see it being out now.
About the sounds: like chip, I would just love it to be realistic: if you don't hear a flare launch, that's fine for me. If you almost can't hear vikhr launches, that's fine for me too.
The only problems that I encountered are the stuttering cannon sound when you fire very short bursts(like1-2 shots), when you just slightly touch the trigger(hope that is understandable, sry for my english:P ).
[i also found out that when you gain height with a lot of collective(close to 100%), the sound is slightly strange. It sounds like as if several sound layers or loops get overlayed in a way that's somehow wrong. It's really hard for me to describe, thus I'm going to make a video to show it;) ]
the last can be dropped, it's not audible on tape, I think I'm somehow making it up, maybe due to the sound of the rpm warning light. Nevermind:)
I'm uploading a short video to youtube at the moment, which displays the cannon sound when you fire very short bursts.
here we are:

and btw.: if the cannon can't be fired in such short bursts irl, so please forget this video and the slighly buggy sound, and just tell us to fire longer bursts:)
