My camera now works as expected. All those "streaming-like" sounds in my video recordings are gone and the sound quality is very good.
I'm attaching the /etc/system/snd_soc_msm/snd_soc_msm_2x_fusion3 file from my phone. Hope it works in 4.2.2
am not having "stream" noise in video recording... but low volume... think it's mainly 2nd mic, which in turn affect noise cancellation functionality.
i guess maybe cm/fxp devs used yuga (xperia z) config on zr, and that's causing a problem???
anyway, too tried to try now, later... later...
