[Q] Notifications and S Voice doesn't work via Bluetooth - Galaxy S III Q&A, Help & Troubleshooting

My Galaxy S3 connects to my car's Bluetooth and allows me to make and receive calls. However, notification sounds are not playing via Bluetooth. It seems that the phone is sending the sounds to bluetooth but the car system doesn't play them. The result is that I have no audible indication when I receive a message when my phone is connected to my car's Bluetooth system.
Similarly, if I try to use S-Voice it would seem that the phone is expecting sound input via bluetooth and not from the phone's built in microphone, which means it does not detect any sound. Audio output also does not play on the phone or via bluetooth.
Presumably my car's bluetooth does not support receiving such sounds - only supporting basic phone functions. I cannot find any configuration settings on the car system to enable it.
Is there any way of stopping my phone trying to send notification sounds to bluetooth and to just play these via the phone's speaker but still allowing the phone to be connected to bluetooth for making and receiving calls? Similarly can I force S-Voice to use the phone's microphone and speaker if it cannot be made to work with my car's bluetooth?

S Voice on AT&T Galaxy Note Bluetooth In Car
First off, I am having the same issue, I tried even holding down talk / voice command button on steering wheel, No luck. I have a 2012 Kia Optima GLI full Nav and Voice command options. I have my Note working nicely with Team Perfection ICS R2, S Voice is fully functional except:
When using S voice in car connected to car Bluetooth (pushing search button on bottom of phone face) it tries to accept audio input from car Mic over Bluetooth, but never receives input. Can't find any setting in S voice app to change input setting from car to phone mic. Not sure why the car mic doesn't work other than just not supported by the s voice app? Anyone out there know of a fix or work around?

s voice does not work over any bluetooth
I have tried this on multiple Bluetooth devices. It does't hear anything and it responds with a very feint. Robotic distorted voice. Music plays well on Bluetooth but I have had problems with phone calls.so maybe the problem is the Bluetooth stack rather than s-voice.

I am having the same problem with SGS3. When I was testing s-voice on SGS2 you could set s-voice to use SGS speaker and mic for voice commands and notifications. Now I can't find that toggle.

BT Devices , yes....Car BT, No
It works fine on my headsets. IT doesn't work in my car.
spanout has nailed the problem. It apparently does NOT use the mic in the phone when hooked to BT. The car is not designed to pass voice to the BT. The car BTs typically have their own voice control, and as such is handling the voice itself.
When you think about it, it makes sense. Less chance for outside noise if it takes the input from the mic on your BT device, as likely the phone will not be close to your mouth.
The only way we'll get it to work is to find a way to enable the mic on the phone when on BT. Probably would need help from the DEVs here on that.

im in the same boat!
the real kicker is SIRI can send her voice over the car speakers and utilize the car mic.
so logic says, its purely a BT setting on the software ice cream and s3.
any apps for that? or any dev's want to chime in?
im using a very simple bmw bluetooth (not idrive).
it cant stream music, so i dont know how the fak siri can send her voice over it.

I have this problem with my SGS3, and had it with the SGS2 in my Ford S-Max. The problem is Ford's. Using the phone with a parrot car kit has all notifications fired over bluetooth.

so switching the s-voice and nav to MONO works with bluetooth, but the a2dp or whatever protocol it uses normally doesnt work.
however calls are done using a2dp, so wtf?
can someone make a quick app that just forces ONLY s-voice and NAV in to mono?
the apps out there make everything go mono or nothing at all...sucks for voice call quality

I needed to revive this thread as a search for my problem led me to it.
1) Is anyone able to play a video on the S3 (GT-I9300 4.1.2) and stream the sound from the video to the car while connected via Bluetooth?
I am not.
2) S3 notification sounds do not play via the car's speakers when receiving a text message or email etc.
I can make and receive calls just fine and even play music from the S3 via BT by selecting the phone from the list of devices on the car's screen.

Blutooth / Voice App Issue - SOLVED
First of all this does work on my 2009 Highlander, but it's a bit Kuldgy.
BT Mono allows my voice app to work, but by itself it's not a solution. You have to activate it manually before using S-Voice, Google Voice or AVX. It opens the connection and has to be activated each time or it can be set to reconnect automatically…. Killing my radio.
Download the free version (I can’t access the play store to give you the link) and see if it works manually. If it works for your test then the rest should work as well.
Install Tasker:
Create a task to keep the screen from locking when your state is Bluetooth connected to the car device.
Create a Task (you don’t need it in a profile)
- Set bluetooth on (in case it’s off)
- Load BT mono (with auto on enabled in the BT mono app)
- Wait ~400MS
- Load App AVX (or S-Voice, or whatever)
- Wait 9 seconds
- Kill BT mono
- Kill BT mono root (it wasn’t always killing BT mono)
I’ve been thinking about trying to simply reboot the BT (BT off then wait then BT on) rather than kill an app.
You can add the task to your home screen as a widget…. Still not safe to do while driving.
That’s where GMD Gestures comes in. You set a swipe command, I use 2 fingers down, to launch the task.
Seems to work pretty well. I can keep my eyes on the road and still use voice commends. You do need to hang up the phone when you’re done talking, but I had to do that with Siri.
I still wish there was a force mono on all connections app, but I still haven’t seen one. AVX just added the ability to force mono for speech, it’s worked for other people, but I’m still trying to figure out why it doesn’t work for me (he's had reports that the Note 2 doesn't like his solution, Kudos to him for trying to add this).
Hope this helps
****UPDATE****
BT Mono may work for me because I'm rooted. According to the app on the store (pro version) Apparently Samsung, in an effort to prevent call recording, blocks the ability to re-route the microphone.
