Stereo SpeakerZ Question

hey i know this sounds dumb but for all without stereo speakers is it possible to use the front speaker along with the loudspeaker(where music nomally plays).
i mean like the earpiece(where you nomally listen 2 phone calls) is quite load aient it possible to Play the eg left on earpiece n right on loudspeaker i know this sounds dumb but mayb it possible it kinda like how when you are making a phone call you are able to switch between the 2 speakers…
MY QUESTION CAN YOU OUTPUT SOUND FROM BOTH AT THE SAME TIME?

Earphone speaker query

During voice calls the earphone speaker seems to sound really muddy to me. So much that I cannot understand what the person on the other end is saying if there is a bit of ambient noise around me.
Compared to my 3G iphone it's terrible.
Anyone else experience this or know if the sound through the earpiece can be tweaked?

Hey even i have the same problem. Got my SGS today and iam loving the phone in all of its bits. Excelleny phone but little tiny bugs and issues here and there. hope firmwares and froyo can make a vast difference in the experience. I dont think they can increase earpiece volume with any firmwares.

earphone and speaker quality
I also am having trouble. The speaker sound is "muddy" or muffled. People I call on the Galaxy complain that I am difficult to understand. I don't have any of these problems on my iPhone 3G, it is much clearer.
The headphones are of poor quality and are the ear canal type which I don't like at all as they don't hold in the ear. The ear bud type of headphone are much better (like iPhone) but are not available from Samsung and I have been unable to find or purchase any other brands that work satisfactorily.
A phone is primarily about voice communication and this is where the Samsung Galaxy s i9000 fails and is disappointing. Everything else about the phone is quite good.

I find the earphones to be decent quality (ipod/iphone earpieces suck!!!).
However I do have also have the voice calls problem. It is a little difficult hearing people on the other side, however they don't seem to have any trouble hearing me.
Maybe we can use one of the "secret" menus in the phone to increase the speaker volume? I haven't looked yet.

2G/3G?
When i'm on 3G networks, i get ok sound, sounds a bit muffled, but nothing serious.
When forcing 2G, i get very clear sound with sifficient volume.
I can at least say it's not a hardware problem.

Muddy sound
The headphones do sound ok, the problem that I find is that they will not stay inserted in the ear and block most other sounds hence why I prefer the ear bud types but I guess this is a personal choice. Unfortunately, the choice of headphone is not apparent until the box seal is broken by which time you have agreed to the carrier's contract by breaking such seal. As Samsung have there own headphone socket and impedance design, other manufacturers headphones are not suitable.
The muddy audio is not so much a level problem but a frequency problem. When holding the phone to my ear, the sound lacks some higher frequencies and hence sounds muffled or muddy if you like. Clearly, others are having similar issues. This should be easily fixed by Samsung and perhaps a control to do so would be ideal then it could be adjusted to suit all users.
When I talk to other people on the phone, they complain that I am hard to understand - again the audio is muffled and a little distorted. This should also be easily fixable.

I feel the same too, comparing it with my iphone 3gs and 3g. Another thing that I'm trying to get used to is the inability to control music fully without having to turn on the screen. On my jailbroken iphone I'm able to use either the standard headset to pause, play, forward, backward, volume up, volume down without touching the phone itself. Alternatively I can do all these actions with only the phones volume buttons alone. I usually connect my phone via the 3.5 mm audio jack to external speakers before I sleep and this feature on my jail broken iphone let's me fully control the music without having to turn on and look at the screen. I also miss my music videos which can be combined with the audio musics in the same playlist and played with the screen switched off. I also miss the fine increment in volume level of iphone, where I can have the exactly volume I want.
I'm also experiencing pauses and skips in music playing.
Viewing pictures and movies is a far better experience on SGS though.

I have a whole different problem with regards to the stock earphones. When I listen to music (via Music Player) and have my headphones plugged in, it does not seem to deactivate the external speaker. So I hear the music coming from the external speaker and the earphones. And the sound quality coming from the earphones is just horrible. I've tested this with a number of different earphones. I've also tested this with TuneWiki and get the same results.
I'm using the latest firmware JG5.
Anyone else having this issue as well?

Could it be some design and or manufacturing flaw in the phone jack itself? I find it difficult to fully push the plug kind in to get complete sound. Sometime I get sound from one side only. When trying to push all the way in the music stops saying that the earphone was unplugged.

Ok looks like I worked out how to get rid of the "muddy" sound coming from the handset.
Enter service mode
*#197328640#
Tap [5] Audio
Tap [1] Handset
Tap [9] Diamond Solution
Tap [3] Voice Booster (mine was off)
Tap [1] , press Menu, Enter "1" as value(without "").
Tap [2] hpf_cutoff
Now you can enter anything from 1-8, 1 will sound bassy/muddy and 8 will sound clearer but a tad harsh depending on your hearing. Experiment with whatever suits you, every speaker may be different. I assume hpf stands for high pass filter.
Now if you want even more volume during a call you can change the [5]limit level to a lower value. Mine was on 21 at default. I've set it to 12 for now.
To exit the menu just press Menu then tap end.
My default values were.
[1] off
[2] 8
[3] 8192
[4] 6
[5] 12
Let me know if yours were different.

Thank you for that info. Fortunately, Optus have eventually agreed that my phone was faulty and I am waiting for it to be fixed or replaced. The info you have supplied may be useful for some fine tuning if required.

Is there anyway to boost the speaker volume in those settings?
Tried to find one but tbh I didn't have a clue what all the settings in the speaker menu were

my suggestion switch to bluetooth, there is always a degree of issues related to wired earbuds / headphones / headsets

Low Voice Calls when on a Wired Headset

When I'm using a wired headset to talk to someone on a call the volume is kinda low, I have it set max but its still pretty low, works fine on speaker or BT. Also the same wired headset works very loud when on a movie or music, just low when on a call.
Any fix to this?

Would like to know this aswell... Impossible to hear what people are saying when using the headset

I too find that headset and speaker volume are low. ( comparison to few other phones )
Cannot hear in a noisy environment.
Tried Volume + but does not seem to help .

I experienced this problem as well. Looks like this is a hardware problem (either the pin or the socket).
Try using a different headset - one without a mic. You sould see a significant gain in volume.
Sent from my GT-I9100 using XDA App

Its a hardware issue, swapped my phone for a new one today and dont have the problem anymore.
The service menu edit doesnt really help at all and the volume gain is minimal.
Anyone else having issues like this should request your carrier or samsung for a replacement. It only happens to a handful of phones.
I assume there are two seperate audio chips, the yamaha one for audio and another for voice calls??
Can anyone confirm?

Microphone low sensitivity when not on speaker

I have noticed an issue that did not exist with the Galaxy Nexus.
When not on speakerphone the microphone sensitivity is down-regulated significantly from the way it is when it is on speakerphone.
Frequently people connect the phone via auxiliary cable in the car (as a hands-free approach), but in order for it to route the audio to the speakers for the car, it cannot be on speakerphone. However when not on speakerphone the sensitivity of the microphone is limited, it is not the same as on speakerphone, therefore unless you have the phone right beside your mouth, the other party will be unable to hear you (due to low volume).
I assume this is an software change in 4.2, I have tested the issue on two Nexus 4's. When turning back on speakerphone, the microphone increases sensitivity again, and the other party is able to hear clearly again.
This poses a problem if you want to have the phone in your car connected to auxiliary and not right beside your mouth/face. I assume they added this because they assume that if the phone was not on speakerphone then it would be right beside your mouth/face during a call, however this is not at all always the case, especially if you connect your phone via aux in the car.
Anybody else experienced this? Any work-around?

Yes, thats really a shame.
I think, it is the noise cancellation. Nexus One has Niose Cancellation, too.
There I've found out, that I have to make a change in the build.prop to disable this
but I really don't know, where to find the line in build.prop to disable the noise cancellation.
And: You have to root your phone to do this.
It's really a shame, I can't use my Nexus 4 in my car plugged into the auxiliary input

hmm anyone can disable it via build.prop?
reminds me a of the days in Nexus one..

I've opened an issue on Google.
Hoping for many votes, that they can see it.

Thank you so much for bringing this up. This is my main beef with the phone coming from my Gnex. Hopefully a fix can be found soon.:good:

My suspicion is that this has to do with noise cancellation. The way noise cancellation works is that there are two different microphones at opposite ends of the phone; the one farther away from your mouth picks up ambient sounds and, more faintly, your voice. The one nearer your mouth picks up ambient sounds and, more loudly, your voice. What gets sent over the phone connection is, effectively, the difference between the signals from the two microphones, leaving mostly your voice.
If the two microphones are roughly equal distances from your mouth, they both pick up your voice about equally strongly, meaning that your voice is mostly filtered out with the rest of the ambient noise. Speakerphone mode disables the noise cancellation, so your voice comes through strongly.

.... as I've said in the second post. Other phones don't have trouble with it.

Exactly. This is not simply a noise cancellation problem IMO. Other phones have noise cancellation too but don't have this problem.

Sorry for inadvertently repeating what you said in that post; it's been nearly two weeks since then, and I had forgotten it had been previously mentioned.
Perhaps the other phones with noise cancellation that don't exhibit this behavior simply turn it off if a headphone is plugged in. That would make sense for a speaker-only headphone, but not necessarily for a headphone with an inline microphone, where the voice microphone would still be nearer to you than the auxiliary microphone. If that's the case, it would be nice if that setting were exposed as a controllable option.

Please look here and add as many stars, as you all can:
http://code.google.com/p/android/is... 4&colspec=ID Type Status Owner Summary Stars
I'm the only one who has told it to google and with one star I think no one will see this problem there.
So we have to gewt as many stars and comments as possible.

Any developers can help with the build.prop line to disable this?
I remember pm founder of cyanogen mod and he pointed me the line to disable in nexus one..

I heard if you get an external mic it is much better but I haven't tried myself. This is annoying because I usually just use the aux with my nexus s with no problems >.< Anyone out there got any other solutions?

Yea seriously bump on this topic. This is a massive problem..

It's the other party not being able to hear when on aux.
Misread.. But Yea if using speakerphone to avoid this problem ull barely be able to hear them, simply not loud enough

Remapping microphone devices

I'm trying to remap my microphones because whichever microphone is used for voice commands, voice recording, and non-speakerphone calls doesn't work, so I'd like to instead be using the microphone that's used for video recording and speakerphone calls as that one does work. I'm gandering at mixer_paths.xml and I see four microphones, main-mic, sub-mic, 3rd-mic, and ear-mic. Which is which? Guessing ear-mic is the bottom hole one that doesn't work. I switched the ear-mic devices for main-mic and it didn't change anything.
Also, is there a better way to go about switching them for the system?

Should anyone else be in my situation, in mixer_paths.xml
main-mic is the bottom microphone. (DMIC2 &DEC2)
sub-mic is the top microphone. (DMIC4 & DEC4)
ear-mic is the physically plugged in headset microphone. (DEC5 & ADC2)
If you replace DMIC2 with DMIC4, and DEC2 with DEC4, your top microphone will work in place of your bottom one.
If anyone knows what 3rd-mic (DMIC6 & DEC6) is, I'd love to know. When I try to use it I don't get any audio input.
