I use imx6q sabresd board to record sound. When I play the recorded sound wave file , I can hear a background noise. Even if i don't plug in the micphone, the recorded sound also have a small volume noise sound. When I use computer to record a sound, the recorded sound's noise is very very small. So, the wm8962's background noise is very bigger than the computer's backgound noise. I want to know is there some setting to reduce the background noise? or the wm8962 itself have a bigger backgroud noise?
The kernel is linux 3.0.35
Hi xu
one can try to rebuild image using L3.0.35 sources:
However this kernel is very old and not more supported, recommended to migrate to more
new kernels described on Linux Documentation web page
