I've been suffering with this problem for six months, all the time I was blocking this problem, but I can't stand it anymore.
 

I use headphones via USB-adapter, and sometimes I lose sound, as if I am far away from the computer (in fact, the distance is 30-40 cm), I have to jerk my head to normalise the connection again. I checked the firmware - fresh, I also use a mat (goliathus extended chroma) and a wired mouse (viper mini).
 

I'm really hoping for your help, I'm exhausted.
