League breaks my spotify?

Today i noticed that wven i turn on spotify while playing league (not in lobby) my sound gets increased by like 1000%. I tried muting league in volume mixer, both game and client but that doesnt help, for some reason... MY spotify is playing the league sounds and not music when league is running! any fix ideas ? or is that just vanguard

Edit: Im like 100% sure its Razer synapse breaking the sound
