Hi all
When using my Hero in my car via its AUX input the remote calling party gets their voice echo'd back to them. Now I'm used to this as I am using this as a cheap car kit solution and have had this on all my previous phones except a nokia 5800. I've done some reading and found that this is due to Echo cancellation issues.
Does anyone know if this is a software of hardware feature in a phone?

Has anyone experienced the following bug: Make or receive a call using a bluetooth headset. A2DP or not, this doesn't matter. Then, use the voice command feature or try to record with Tape Machine, while your headset or car kit is still conencted. The microphone won't activate. This is quite aggravating if I try to use the voice dial or map finding capabilities while in the car... anyone else experience this?
i have the same problem when my phone is plugged into the aux in my car. the mic just stops working :/
I can verify this issue. I most want to be able to use this feature while in the car and using hands free, but I can't.

It's annoying - my EVO didn't do this before I returned it.
I ordered a few inline microphone adapters for $2 each on ebay with free shipping - they're the things that allow you to use any pair of headphones with a cell phone as a headset. That should solve that problem, but it'd be nice to be able to use the phone mic when it's connected to my car stereo, as a speakerphone.
I guess the way Samsung saw it if you plug in a headset with a microphone(like the one included with your phone) you would then have 2 working microphones and get an echo. We all know this ends up being a problem in scenario #2 where you plug it into the AUX port on your car, but I guess Samsung did not consider that the most likely usage.
The best solution would be to have a software toggle to pick if the microphone is turned off or not.
This topic is basically the same thing, might want to continue the discussion there. http://forum.xda-developers.com/showthread.php?p=7986072
I wonder if, on the Epic, this is a hardware thing we're stuck with or if there truly is a software fix.
If the hardware wasn't built to detect when there is/isn't a microphone by checking out the connector, we may be SOL.
While I'm sure the rationale may be the same, please note that this thread, though similar to the 3.5mm headset thread, specifically references bluetooth. The issue happens even if the headset is paired - independently of whether or not it is in use. That's the problem.
just unpair bluetooth when you want to use the speech. only work around so far.
i've searched the forums about any type of noise cancellation app for the HD2 and really can't find anything. i know some phones have the noise cancellation mic and this one doesnt. but is there any app that anyone knows of that will help with background noise cancellation for this phone during calls?
i try to use some of the android voice features like voice texting and whatnot while i drive, but because of background noise it never hears me correctly. any help appreciated. thanks.
p.s. and no i don't try to use it while driving with the windows rolled down and radio blaring lol.
Noise cancellation
Since the HD2 doesn't have dual microphones I'd recommend you invest in a good Bluetooth headset like a Jawbone or BlueAnt....
Hey,
usually I have plugged my phone via cable into my car radio. So I can listen to music and making calls and I can hear the other side crystal clear over my car speakers.
So it was with Galaxy Nexus.
But with Nexus4 it seems to be impossible. My partner can't hear me.
It seems, that the noise cancellation is active and filters my voice out.
Thats very annoying! Has anoyone made the same experience or a solution for this problem?
I don't know of there's a software solution. Simple $30 hardware solution is a Belkin Bluetooth car adapter. Works with calls and music. Nice. Check Amazon.

I take my calls through Bluetooth to my cars radio and it works really well.
Yea I can confirm the problem happens when on auxiliary in the car, I also made a thread about the same issue http://forum.xda-developers.com/showthread.php?t=2027956
Yes, I've seen this too late, sorry!
On Nexus One we found out, that there is a line in the build.prop, which enable/disabel the noise cancellation.
But on N4 I can't find this service.
I don't have bluettoth in my car and it's a software problem. Why is the Noise cancellation enabled while using handsfree? Thats very dumb.
Used the phone through my AUX input in my car to make a call the other day, bit of a delay in the person hearing me at first but after that no problem...could have been a bad signal on one of our phones too causing the initial delay too
My car pairs to my phone without any issue, but none of the voice apps I've tried (Google Now, S-Voice, AVX) can hear me when I attempt to talk with them. The closest I've gotten is it hearing me but playing my voice as a delayed echo over the speakers so anything longer than 3 words and the speakers drowns out what I'm asking.
Using BT Mono I can use the voice apps the way I should be able to, but it needs to be connected before turning on. I came up with a really hokey workaround using Tasker and BT Mono with screen gestures, but it's inelegant and not %100 reliable.
I've looked into this and still haven't found an answer, is there a way to force the Note II (ATT version) to always use Mono over Bluetooth without passing voice back to he speaker while I'm talking?
This occurred with stock kernel and I've just switched to the Perseus Kernel http://forum.xda-developers.com/showthread.php?t=1983658 (Thank you AndreiLux!). on a rooted phone. If anyone has a better way of handling this or knows why the Note II is wonky with several of the other Bluetooth apps (with the echo issue) please tell me?
When i connect my i9195 into my car, i can hear the person that dials me, but unfortunetly that person hears himself as well. That must be because of the car speakers, but is there a way to reduce that echo voice like in every navi cars, or voiip software?
update:
another interesting thing... I have tested the same situation with diffrent phone - Samsung Galaxy S3 with original firmware, and voice echo cancelling works just great. So the solution may be to abandon cm10 and install original firmware, but i really love cm, any solutions?
