Many people have this problem with Android. You can see it has been reported in Android's bug tracking system. The number of levels is controlled by a setting that's compiled into the Android system image.
Use a different ROM
It's possible that flashing a custom-rom could increase the number of levels, but I don't know which, if any, custom ROMs do this. ...

Dev0 and hello are correct - no you cannot connect using your Android device as a A2DP sink given the standard Android bluetooth stack. Stack Overflow user Dennis Mathews explains why:
You may not be able to [create an A2DP connection] manually between 2 phones also because to stream one device needs to be A2DP sink and other other A2DP source; phones are ...

Have a look at simulating keyevents on Android and search for "KEYCODE_VOLUME_UP" and "KEYCODE_VOLUME_DOWN".
Events can be generated by executing "input":
#local shell:
input keyevent 24 #vol up
input keyevent 25 #vol down
#remotely using ssh
ssh your-phone input keyevent 24 #vol up
ssh your-phone input keyevent 25 #vol down
# 'su -c command' to make it ...

media-button-router, already mentioned in one of your linked questions, tries to figure out what app is currently playing music and to dispatch the AVRCP events to it. In addition, it lists all apps installed, that declare to listen to AVRCP events.
What makes AVRCP complicated: Some apps, like Sony's Music Unlimited, seem not to declare android.intent....

Today i have made some progress in this question.
On iPhone you can buy a iRig Mic which can do the job (and it should work on android too).
But since i want to use another external microphone i have decided to make the adapter myself from some different adapters (which does the same thing as iRig Mic, but with a female 3.5 mm jack output, so i can use my ...

Most likely it's a difference in the TRRS layout of the headset.
For example, I have two "similar" headsets, one that came with Samsung Galaxy S and another that came with Samsung Galaxy Tab 10.1. Even though they look similar to the naked eye, if I use the Galaxy S one with my Tab, I only get mono sound due to a minor difference in the TRRS layout.

On my Cyanogen 10.1 phone (AOSP 4.2.2), it is possible to enable a capture of bluetooth traffic. You can then load this capture into Wireshark and look at the negotiation phase to determine which codecs the paired audio output device supports. Not sure what OSes support this: when I first ran across this method it claimed support only from 4.4 onward, but ...

Solved: The android system is likely connected to the headset for phone calls, and some other device for A2DP (media). Some other device is still using the audio connection, even though the sound comes from android's speaker!
What this means is that if you have any other A2DP devices that you've paired your android with (laptop/stereo/etc) then you will ...

Yes and no. The fact that your Galaxy S3 does not support mass storage mode means that you cannot play audio files stored on the S3 with the radio, like you could with a USB stick. (If your car's radio supports mass storage, that is.)
However, the other type of USB connection, allowing your iPhone to be controlled by your car's radio is an Apple Accessory ...

You can simply use an app like Earpiece. It does what you want to do. You can pop Earpiece up on top of another application simply by holding down the SEARCH key. then check Audio through earpiece
On a side note, USE AT YOUR OWN RISK. Playing audio at high volumes, especially for a prolonged amount of time, can damage speakers and/or hearing.

HE-ACCv2
AMR-NB
AMR-WB
FLAC
MP3
MIDI
Vorbis
PCM/WAVE
As the documentation also notes, manufacturers can provided decoders for ...

Looking at the source, there are at least 4 codecs: SBC (mandatory), MP3 (MPEG12), AAC (MPEG24) and Sony's ATRAC.

There is a possible quick solution, depending on the phone in consideration:
Go to Settings->Sound->Music Effects and depending on the phone, you may by default have an app that controls the music effects within which you should easily find your desired setting.
But if your phone is rooted, a more reliable solution would be to install the music effects app/...

To change or turn off the sound, touch "Tone", and ...

Currently you can't disable notifications via speakers while still having them via headphones. There's an open issue for that.
You also can use Llama or Tasker to switch profiles when you plug your headphones.

It is not possible via bluetooth on Android, only from phone to PC, not from PC to phone...

With Nexus 4 (5.0.1) or Nexus 7 (2012)(4.4.4) devices it is possible to use the developer mode to get the btsnoop_hci.log. "Enable Bluetooth HCI snoop log". It is not necessary to root the devices.
It seems that both devices don't offer aptx.
I test this with Moto Stream (no aptx) and Philips AEA2500 (with aptx).

As far as I know audio amplifying circuits will have a fixed amplifying ratio (gain). By adding resistance (either digitally or using analog POT) on the input (or output?) signal the volume is reduced. Hence in my opinion it can't be done.
Switching over to in ear phone buds like:
instead of: will provide better noise isolation and there by improve ...

There seems to be a pretty bad bug that affects Cyanogenmod right now

Yes it is possible.
I'm doing this with several devices for amateur radio and video production with KineMaster Pro.
For amateur radio, I use the DigiMaster MiniProSC connected via OTG cable to a Nexus 9 via OTG cable. I also do this with SignaLink usb connected the same way. Both of these devices have internal usb sound cards with audio in, audio out, and ...

Unfortunately, Android and IOS specify different hardware specs for the remote feature. The way the clicks get registered by the devices are not compatible. Sad, but true.
There are very few good solutions that I've found, but I have found a couple. So far, the best I've done is this combination:

I visited this some time ago and explored some values within the file. As it can be hard to determine sound quality comparisons, I also compared the visual appearances of waveforms.

I wrote an app named SoundAbout. It has a feature to have the sound go though your media output selection AND the speaker. It also allows you to NOT have the notification audio go through the speaker.

From the XDA Developers Forum, I have implemented this solution successfully on my Samsung Galaxy S Epic 4G (with GingerBread.EI22 and also GingerBread.EL30), which has eliminated the "Battery fully charged.

Stops the vibration.
Silences the sound.
