So, I have two quick questions that i hoped i can get some answers for :]
1. You know the low battery warning message that doesnt allow you to use your camera/music player etc when your battery is below a certain percentage? well i was wondering of there was setting or a hack to remove it.
2. The audio quality when recording hd video is really low. not only is it mono, but its like 63kb with a really low sampling rate. If i recall, i remember the omnia hd had terrible audio quality at first, but it was fixed in a later firmware. Will this ever be fixed on the galaxy s/captivate, or has it already been fixed?
Hi! Anybody tried the video recording function on their HTC One on normal environment sounds? It seems too low for me to the point that I need to crank up to the fullest volume when I want to hear the sound of my TV when viewing the video. And yeah that's beats enabled
Everything seems to be working Except for the video brightness dims up and down. Similarly the audio volume does the same thing. Any ideas?
Could be your TV. Many TVs have settings to dynamically adjust the picture for best contrast in light and dark scenes, and also to automatically adjust the audio volume compression. Most people prefer to turn those settings off, but they are often on by default. If you haven't used the HDMI input that the Chromecast is plugged into before, those TV settings may be on by default and affecting your picture and sound.
When I record video the is a high pitch sound, in stock, or in CM 11 I still get the high pitch noise. I did notice that in cm if I change to sound encoder to amrnb no noise but not as good audio recording quality as in aac. Has anyone else had this problem and can it be fix or is it something to do with my hardware.
Although the Nexus 6 has 3 microphones (one built in the bottom speaker hole, one on the back plate close to the Micro USB port, and one next to the back camera lens), it looks like audio is always recorded as mono when shooting video. Furthermore, the audio is always captured from the front mic in the speaker hole, which means that it takes the sound from the opposite side of the camera lens.
I've also tried with other camera apps (such as Cinema FV-5 which allows to select between mono and stereo audio) but the audio is recorded mono anyway.
I've then checked the file media_profiles.xml in /system/etc/ and found out that basically all different resolutions had channels="1" , which means that only one (mono) audio channel is recorded.
I've tried to change channels="2" and rebooted but still all audio was recorder as mono and from from the from mic instead of the rear mics.
Any ideas on how to get stereo audio recording?

First of all, I do not have access to a Nexus 6, but I recently made a stereo recording mod available as part of my "larger" Nexus 5 camcorder audio fix over in the Nexus 5 General section.
On hammerhead, the spatial aspect of the stereo recording is surprisingly impressive (although one channel suffers from some "coupled noise").
It helps a lot that the two microphones seem to be of the same make and model (according to the LG service manual). It is also advantageous that the two microphones are symmetrically
placed on the sides of the phone, where scattering and diffraction effects help with spatial separation.
To me it is not clear whether the same level of spatial effect can be achieved with the Nexus 6, but it is worth a try.
I took a quick look at the mixer_paths.xml file where additional edits to enable stereo recording would be required. I can probably help you in getting some form of dual-microphone
recording to work, but there is likely some back-and-forth testing and manual system file editing required. Shoot me a PM if you are interested in pursuing this.
@chdloc has found the solution to this (thanks!)
