3.5 Audio Jack for Mic Boost - General Questions and Answers

Hi,
I have the following question, most (maybe all) smartphones have a 3.5mm audio jack which also allows headphones with a mic (included with some phones) since it has TRRS.
What i want is a way to connect a normal mic which is TRS (i has have a TRS->TRRS adapter) to that 3.5 audio jack in order to increase the mic volume in my phone, one main reason is when my phone is connected via bluetooth to some speakers like in the car, it will automatically decrease the mic volume.
Any suggestions?

Anyone?

This is really annoying as bluetooth lowers mic volume to almost noting...

I have discovered that mixer_paths.xml file might help in boosting the mic on bluetooth and that it also might a cyanogenmod bug...
Is anyone familiar with the values in this file and what they mean?

[Q] Headphone jack is reversed

When I plug in the headphones it sends the sound to the external speakers while if I disconnect the headphones I get no sound at all. If I reboot and leave the headphones in it routes the sound to the external speakers and the headphones.
Any suggestions? Software or hardware solutions?
Also is there anywhere you can order replacement part for our tablet?

[Q] How to enable Audio output via 2.5mm jack and Bluetooth

Hi All,
After much searching for this simple request, how to enable Audio output to the headphone / 2.5mm audio jack and output to bluetooth speakers at the same time.
This is not a request how to get music to play on bluetooth mono headphones etc.
I am wanting to have my Nexus 5 plugged into the speakers and amp in one room, then also have my UE Boom in the next room playing audio via bluetooth.
As soon as I plug in the speakers via the jack, the bluetooth sound output is muted.
Going into Bluetooth settings and unticking music and then ticking music starts audio playing via bluetooth but stops audio via 2.5mm jack.
Any settings I need to know about? Apps or custom ROMs to do this simple feature.
Think of this as a keep playing to speakers when headphones are plugged in. Possible in Ubuntu, is it possible on Android?
Many Thanks,
Rob.

Just to bump the thread, as I know how fast paced the Nexus 5 forum is, and I have waited 10 days before re-asking.
Anyone with information that could help?
Many Thanks,

Splitting the 3.5mm jack with microphone and speaker output - possible?

Hi All,
I was wondering if the below scenario is possible with any android phone.
- Plug a 3.5mm splitter into the audio jack (two female ends)
- Plug a speaker system (headphones, whatever) into one split port
- Plug a microphone into the other split port
Would the phone play audio (music, etc) through the headphones normally? If someone were to call, would the voice on the other end play through the headphones and the microphone work for me to talk to them through?
Thanks!
EDIT: Since the response has been overwhelming I went and tried the method above. Works perfectly. Thanks to... me *self high five*.

Bluetooth speaker. Listening?

I was wondering if and how to use a Bluetooth speaker with mic a two way intercom (speaker and phone as each end)? I want to be able to listen in another room and be able to talk through the device also. Ideas? I currently have a small portable speaker with mic that I can stream audio from the phone to.

Permanently disabling headphone jack using build.prop?

Hello!
I can't use my phone's earpiece speaker during calls because the phone insists that a headphone is connected to the headphone jack, despite the fact that the 3.5mm jack is already removed from the device (had a repairman remove it for me).
Apps that should do the trick work only halfway (it reroutes media audio but not in call audio. I have to put it on speaker mode everytime I do a call.)
So, the question is, can I disable wired headset detection on my device using build.prop or any method that tweaks the OS itself? My phone's rooted, btw.
Thanks in advance!
@BsofBordeaux Did you find answer for your question?
