Hello ALSA devs,
I spoke to patrakov on Freenode from the #Alsa IRC channel and they mentioned that the noise background I am experiencing is not normal. I tried two different headsets, both headsets have two separate jacks, the same result.
I will test any patches/quirks for kernel as needed.
Here is the alsa-info:
