adjusting volume balance between two speakers - Android Q&A, Help & Troubleshooting

hello..since this part of a forum allows to ask questions not really related to cellphones...i have a problem...one of my stereo system has no function to control sound balance between my two speakers ... is there any way of adjusting speaker balance volume?
one of my speakers happens to be close to my desk and i would like to redirect sound to the other one standing farther in the room..
yet that stereo system i presently use x-hm72 pioneer seems not to have balance function on the body or the remote.
I tried to play local music from usb, so i guess no luck with that..yet when i cast music from my laptop..i hoped that a laptop could manage balancing... and somewhat sound comes out of the box with equal power to box speakers...
so - how to force the system to obey balancing to one speaker?
i know ..i could disconnect the closer speaker when i am near the desk... and connect back when sitting in my armchair... yet that is not the solution i prefer to use
thanks..

[Q] HTC Touch Pro 2 Headphone (Music) Volume level

So I've been trying to figure out why it is that my Touch Pro 2 which I am just now getting into using as a music player (late bloomer I know) has such a LOW volume level with the 3.5mm headphones (using the mini-usb adapter that it CAME with). It seems that the volume level is only absurdly low on items played with HTC Music and Windows Media Player. Other apps I have tried, such as nanoGroove and ICYGroove seem to not have this volume level issue, meaning that it's loud like I want it to be without distorting to nonrecognition.
I've tried hacks and other apps that claim to make a big difference, such as Advanced Configuration's ability to turn on the HTC bass/treble/3D sound boost, which ends up with major distortion. And "Audio Booster" which does make some improvement on HTC Music but not nearly to the level that I hear music from nanoGroove and ICYGroove on.
So the question at this point I guess is, is there any way to get around this or safely and sanely amplify the volume level for music from mp3s? nanoGroove and ICYGroove are both kind of questionable because the sound data comes from an external source (the internet) so I have no idea if they run it through some level amplifier to begin with and that's why it sounds better, or if it's the program itself that is piping it through the sound system differently.
The only other alternative I can think of at this point would be to re-encode my mp3's with a higher volume level, but given my diverse music tastes and frequency of shifts from one artist/genre to another that would end up having to re-encode pretty much everything on a regular basis which I would really rather not have to do. Not to mention having "phone versions" of all my music..
If anyone can recommend something that would either clear this up so it made sense, or just replace the HTC Music/Windows music players in general with something that does not have this problem or an easy and sane workaround, that would be hugely appreciated.
Thanks!

[Q] Optimus V Headphone Volume for MP3 Player Use

I got the Optimus V at the recent Cyber Monday deal at Virgin Mobile - for one major purpose - to use it as an mp3 player for my car. I have not activated the phone, do not plan to, have wifi on it only.
The built-in speaker on it is pretty loud, so I am surprised that the headphone volume is very low. I have to turn my car volume all the way up to max to hear anything (driving highway).
I wonder if LG turned the volume low to prevent people from killing their ear-drums. Is there any solution out there without having to activate the phone and install alternate rom on it? I have turned the volume in settings all the way high, and I have Pandora, and I have set the audio setting to high on Pandora preferences.
Pls. let me know if my objective cannot be achieved without rooting and installing a custom ROM, I would prefer not to activate this phone.
Thanks for any help.
Shameless bump...I have Volume Control+ which does not help at all.
you hear low sound in headphone ?
what are you connecting it to?
Yes, I have a low volume on the headphone too. I connect it to the aux port on the car radio using a regular Stereo Jack. My Car radio is a Pioneer system, which has great sound with other mp3 players.

[Q] Surround sound problem?

I have a CT802 Idea USA tablet running Android 4.0.3. It is rooted.
Whenever I try to play a video (using any media player program including but not limited to the built-in one), the audio is weird--the volume is relatively low *and* the voices are almost nonexistent--what I get is almost all music. This is only a problem when I have something connected to the headphone jack--it does not happen with the built-in speaker.
If I plug the jack partly in, it is possible to get it into a position where it plays the sound properly.
My theory is that it's somehow falsely detecting surround sound output (but is not detecting it when I have the jack partly in), and when it does so, I'm only getting the left and right channels. I would like to know:
1) Is there any way I can prove this?
2) Is there some setting buried in some file that I can use to disable surround sound completely?
It turned out that the problem was caused by having earbuds with a built-in microphone. Both of the ones I tried had a microphone. When I bought another pair without a microphone, sound was okay.
It's still a problem, however. How do I keep it from doing this? There are no system settings whatsoever related to microphones, and I have no idea how to disable the microphone or otherwise tell it to treat the earbuds as a normal set of earbuds.

Volume differences between bluetooth and aux output.

I'm the kind of person who likes to use my phone as a GPS. Google's free navigation used to be a selling point for the OS, but it currently has some issues. Prior to Android 2.3, there used to be separate volume levels for media and navigation. However, these got combined into media so you can no longer tweak your navigation volume independent of your music. The end result is that the only way to make navigation audible in the car is to have the stereo volume at a level that would cause the music volume to bother many people (I usually drive with two toddlers in my car).
But there's another thing that I noticed. Switching between bluetooth output to line output (the car's AUX input) has an effect on volume, but not one that makes sense. Music played through Google Music (and other media players, including PowerAMP) is louder over bluetooth. I have to have the volume at 2 bars in my Fusion on Bluetooth to match the music volume set at 4 bars on line out. But here's the weird thing, navigation volume is not effected. It sounds the same on both, meaning that it suddenly becomes audible on line out.
Android is doing something weird where it amplifies music over bluetooth, but not other sounds. Anyone have any ideas on how to alter this? As it stands, bluetooth is more convenient, but it makes turn-by-turn navigation more difficult.

The most interesting Bluetooth headset - Sony MDRZX750BNB

Sony MDRZX750BNB is a recent model of Bluetooth headphones which also provide noise cancelling and some other very interesting features.
The noise-cancelling part is working OK, it is still debatable if that is as effective as the top of the line Bose noise-cancelling headphones (which are not wireless) but in car and plane the noise cancelling is quite effective.
The wireless connection is actually made of two different connections (which can even go to two different sources) - one for "call audio" and the other for "media audio". If the "media audio" is not by default in the high-quality aptX/AAC mode you can force that (check if the blue LED blinks in groups of 3).
Sound is IMHO good towards very good and the buttons are well-placed (for a right-handed) and provide all the functions you need most often (play/pause, answer/reject, skip fwd/back, you reject a phone call with a long-press on the pause/answer button).
Battery life is OK (you can extend that by disabling noise cancelling when not needed and I believe you can also use it wired when completely discharged). NFC is also very handy.
The manual is kind of basic from the technical point of view but there is a good guide online from Sony:
http://helpguide.sony.net/mdr/zx750bn/v1/en/contents/contentslist.html
I did find one extra positive - the headphones are great to keep warm your ears/head in a cold/windy day.
However now the summer is coming this might also become a problem when it is too hot outside
