I use Avermedia A835B(2835) roughly a half year. After installation everything was fine, usb stick was registered and running well.
I used it after several month again (it is only backup source) and I observe distorted sound. The same result is on both Solo2, which I have,
but if I use it on Win7 or Win10, sound is ok. It seems to me that it is related to latest kernel change when probably some libraries have been changed.
Could somebody help me to find the reason and possibly to fix it? Thanx in advance.
