Subject: [Intel HDA][ALC3226] Too much white noise from microphone
Date: Wed, 04 Feb 2015 16:13:08 -0500 [thread overview]
Message-ID: <8841801.KiuVFG1hDJ@segfault> (raw)
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:
