Samsung Galaxy S3 i9300 Bluetooth headset has no sound during calls - Galaxy S III Q&A, Help & Troubleshooting

I can listen to music or videos with Bluetooth headset but if I place a call there is no sound during the entire call.
I’ve tried many different ROMs. There are some 4.4.4 that doesn’t work but most do. Anything higher and up to 7.1.2 does not work. Tried with 3 different headsets. Have searched but find either no answers, sound quality issues, or problems with car stereos. I have heard there are Bluetooth problems in general but doesn’t seem to be much talk about no sound in calls with Bluetooth headsets. I have heard there are Bluetooth issues with Lineage OS but I have not heard about no sound during Bluetooth calls.
I’m I missing something obvious? I was thinking about asking about this in some ROM threads but thought I would try here. as it happens on almost all ROMS. I’ve tried a bunch of random things short of throwing it against the wall which I guess would make the problem go away but technically not fix it. So if anyone can offer suggestions and make me look like an idiot, please do.

Have you made sure that both options in Bluetooth settings for audio and voice are checked?. You might need to look for an advanced option menu?..

[Q] Re-directing all sound to Bluetooth

Anyone know if its technically possible to get the sound routed to standard bluetooth 'hands-free' device. I know I've successfully done this on all my past devices with help of 3rd party software. I see several iterations of software for android out right now, but none have worked for me on Atrix.
I know buying a AD2P headset would be the ideal software free workaround. But I've tried a lot of bluetooth hands-free out there, and the one I have now is just so comfortable, I just can't switch to A2DP until it absolutely dies.
I've seen a few people requesting this across other forums, wondering if the Atrix is even accessible programming wise to do this?
thanks
I don't understand your question. I have a bluetooth headset which I play music on, and which auto cuts music for calls, has a mic, you can dial by voice command, etc.
It's hands free like any other bluetooth headset other than the power button, volume buttons, etc.
What exactly are you asking?
I believe OP is requesting any App that can be used to Hear Music on a Mono Bluetooth Headset which do not support A2DP Profile.
Using regular Bluetooth without A2DP profile will allow us to Just make /Receive Calls, not for Music.
I also tried BT Mono, but it didn't worked for Atrix and eager to know any other way we can able to hear music thru regular Bluetooth Headset

SakDroid is correct. Not all bluetooth headsets support the AD2P profile, and some phones won't play music to them for a reason unknown to me. I've had 4 phones with this same bluetooth headset and only one of them natively would play music with it. All others I had to install app to redirect sound...such as the referred to BTmono. So I know it's possible on Android, just wondering if there is something preventing it on the Atrix, or just hasn't been developed yet.
I would gladly pay to get development started on this. Since I would have to pay money for one supporting A2DP, but you know how it is when you have that one that fits/works just perfectly. I've bought a few that do support the profile, but ended up returning them all, as they just weren't comfortable to wear very long.
Btmono worked for me on my samsung epic 4g on froyo....then sprint sent an ota update to their version of gingerbread 2.3.6. it is very phone specific with what your carrier puts out I think because my wife has an stock htc evo running 2.3.5, and my brother has samsung epic touch running 2.3.7 and both of those different phones work fine with it. So what did I do....I found a custom rom that was built off 2.2.1 froyo. I didn't read the full thread so I don't know what exactly what phone this is for. Only option is to get to know everything you can do with you phone, root it and try different roms. Young and old. Also...on the eipc forum we had a discussion about this....they all had the same issues with gb...even the custom roms. Would love for the developers to learn a work around, since is up their ally...but shortly after there was a good leak for ice cream sandwich which I tried and its pretty good...just a bit buggy for me. When all the kniks are work out will be moving onto that and bypassing any gb that is out for the epic. So my advise, again, is just try different stock roms first....just to find out which ones...if any will work. Then you will know what custom one to look for...if you into that sorta thing.

[Q] Bluetooth problem

Hey all,
Need some help with this, getting quite frustrated:
I have an international S III (i9300) and whatever rom I use I have the exact same problem that seems to be related to bluetooth.
- First use it connects to my caraudio (pioneer deh-4400bt) and it works great, good sound etc.
- Than I start Sygic (navigation) on the Phone, which I set in the "Always use internal speaker mode", so it doesnt use BT
Now two things happen:
- In sygic the sound through the internal speaker is very soft
- When I try calling with the carkit it does connect and make the call, but I hear a terrible garbled sound and i don't hear the other side
When I turn off bluetooth and than start Sygic... sound is perfectly loud
I have tried several roms, lastly thinking the issue might be solved with 4.2.2 but still the same
Is bluetooth hardware or software, and, when software, is it kernel or modem related?
Anybody know what causes this problem and how to solve it?

Bluetooth on lollipop roms plays slow

I haven't seen anyone else post this yet so I'm hoping someone can help me out. I have a Bluetooth speaker in my car that works fine on stock or on kit Kat roms. But on every lollipop rom I've tried, the audio through the Bluetooth is slightly slowed down (resulting in everything sounded a little lower) and kind of choppy.
The audio plays fine through the phones speaker or through a headset, it's only on Bluetooth that this happens.
Any body else having this problem? Any suggestions?
Same issue here.
I think it may be the speaker I'm using, because I had the same issue when I connected my tablet to it that is also running lollipop. I need to find a different Bluetooth device and see if the problem persists.

I was doing a search on this issue myself, which brought me here. It's actually only one speaker I have that does this, and it's the newest BT device I have. It's the HDMX Rave portable BT speaker. It worked fine with the KK ROMs I was using at the time I got it, but ever since updating to LP, only that speaker of all the BT audio devices I own does that.
Weird...
Similar Issue
Hi,
I've also experienced this, although it seems my Bluetooth plays much worse than yours. It's slow for a bit, then choppy and breaks up, then it'll speed up the music to get back to where it should be. It renders Bluetooth music completely unusable.
I've found:
High CPU usage causes this in KK (skydragon) for me. The high-usage culprit is the netd module, not sure if that's relevant.
I've flashed Jasmine Lollipop (5.0.11) lots of different ways, with several different modems, and it still has this issue.
It doesn't seem to depend on the app, as it happens with the default music app and with Spotify (192 Kbps).
It happens on both of my Bluetooth devices, a cheapo portable speaker and my nicer car stereo. I don't know the BT versions they use.
Disabling WiFi helps a little, disabling data does nothing.
Anyone have any workarounds?
i had the same problem when connecting to my car speaker.
funny thing is some days it works great, and other days all of a sudden it just plays all slow. anyone got fix?
So I've been doing some more tinkering. Turning off WiFi will fix the issue for my "dumb" bluetooth speaker (it's a pair button and a power switch only), however it will only fix the issue for the first ~3 minutes on my Clarion car stereo (with all sw updates). I've disabled literally every Bluetooth service, activity, provider, and responder that isn't essential for A2DP connections. I'm able to access the hidden menu item for Bluetooth testing, but I don't really know how to use it. If someone has directions for that I'd gladly put my phone through the paces.

Android audio routing

Hi,
I got a problem that my Samsung Galaxy S5 route all audio to earphones.
I would like to route all media to speaker and all phonecalls to headset (and if possible bluetooth).
I don't mind customizing ROM if needed.
Any idea how can I do that?
Thanks!
Help?
first: ask with understandable words. lol i don't know what are ur plans
i know this is really old but to anyone having these issues, install soundabout you can use it to force audio to a certain output for calls, media, ect really helps when your headphones start to break and android doesnt want to detect them even though they work
EDIT: I misunderstood the last post as a question. Didn't mean to repeat the same answer to an old thread.
Not really a full answer but I am currently having similar issues. There seem to be audio routing apps like Audio Router (https://play.google.com/store/apps/details?id=audiomix.audiooutputsource) and SoundAbout (https://play.google.com/store/apps/details?id=com.woodslink.android.wiredheadphoneroutingfix) than can do the job. I can't exactly tell how they work but maybe someone else knows. Or you'll figure it out.
Feel free to post your results
Have the same problem. But neither Audio Router (https://play.google.com/store/apps/d...ooutputsource) nor SoundAbout (https://play.google.com/store/apps/d...oneroutingfix) can't route SMS notification away from headphones.
Sounds terrible. Most modern android smartphones are worse in this regard than ordinary simple cell-phones.
I wonder how things are in this regard in Windows Background.

Forcing calls to go through A2DP in Android, while using the phone's built-in microphone.

Hello,
This issue has been driving me insane. It seems like some simple, artificial limitation that no one seems to circumvent. As the title suggests, I'm trying to force phone calls and especially VoiP calls (Discord, whatsapp..etc), to go through the high bitrate A2DP profile instead of the horrible HSP/HFP profile that butchers audio quality and uses the horrible bluetooth microphone.
For instance when music is streamed through a bot in Discord i have to listen to it in horrible earpiece-level phone call quality.
I feel like there's got to be a tweak, a Magisk module, a custom ROM functionality with root access that allow for this, something.. I found a couple old XDA posts about this but no solutions. Oh and also tried Lesser AudioSwitch on multiple Android versions, none worked.
It seems inherent to all bluetooth headphones which is a shame, they could cost 10k $, but the quality would still be sh*t in calls, both in and out, since mic is not close to the mouth.
I always loved Android for giving users more control, but sadly seems like this is more and more going away. What i want here, can very easily be done on PC.
Thank you for your time reading, really hope someone can help.
