Camera issue in all Custom Stock Roms like CN (non touchwiz roms)

The issue I'm talking about is not about the quality of images or video graphics that the camera can capture or record>
the issue is with the quality of the sound in video recording in non touchwiz roms like CN or other custom roms installed on samsung (mine is S3) , the sound in those roms is sucks in comparison with sound recorded by camera video in touchwiz based roms.........
my question why? and how to fix if there is a fix? because usually the non touchwiz roms are faster the touchwiz based roms but the microphone in those roms works better. I think it is really important thing.


ANd THnx already:D
