Counter Strike 2 with Discord sound problem

I have Razer BlackShark V2. For some reason recently (I feel like after last updates on Razer Synapse) I started facing with the following problem:
When I’m playing Counter Strike 2 with Discord, from time to time the sound in CS2 disappears randomly during the game. I mean it’s like disappears for 5-7 seconds (sometimes longer), then appears, then disappears again, then appears again and so on. The weirdest thing here is that it’s not like fully disappears, I would describe it more like I’m underwater and don’t hear things for couple seconds. Just don’t know how to describe it better :)
As I mentioned above, the problem exists when I’m in a Discord call during the game.

Any thoughts here ?

Thanks!
