WOW - small lag, lose sound - small lag - sound returns

is there some tracker for issues? i noticed small lag while playing wow - like one second long - then game would continue - but without any sound - and after like 4 seconds i would get another lag and the sound would return?? had no idea if it is memory issue, SSD issue, my sound card, or anything else

I have Nvidia GeForce 3060 Ti, IntelCore i5 10400F,
