Razer Kraken 7.1 V2 Mic not working properly when Razer Synapse is not running

Hi all,

Yesterday I did some changes on my headset's settings using Razer Synapse, then after exiting the Synapse the mic becomes chappy , but when the Synapse is running its clear.

Heres the recorded sound: https://voca.ro/dstKsoTc7zz

Heres the configuration:


Does anyone knows how to fix this issue?

Another question, how to restore default settings of my headset?


Thanks,
NicoTing
