[HELP] Strange MIC issue while driving. [HELP] - MTCB Android Head Units Q&A

Hi,
I was wondering if someone can help me out.
I have Xtrons TE706PL which comes with this BT module http://www.datasheet4u.com/datasheet....php?id=944249
I used a recording app to test the quality of build in mic that i replaced. Below, i attached links to three files that are my recordings. I have the following issue. When the car is parked and i click record button it records the quite and there is almost no audible noise other than a little white noise. Then once i start driving and repeat the process, i hear some type of screech or something. These files are for comparison.

Highway Driving: https://vocaroo.com/i/s1kSHLiabexf
Driving and stopping: https://vocaroo.com/i/s1pJ4lnMBDLq
P.S
When my car is in ACC mode and radio is on with nothing playing i heard some crackling noise though car speakers, nothing loud. I narrowed it down to WiFi. When there is some data RX or TX i hear that noise. When i disable WiFi its silent.
If anyone has suggestions it would be greatly appreciated.
Thank you.

Bizzare Speaker/Sound Problem

Hi All,
This morning I was listening to my favorite Podcast through the speaker of my SX66. I then headed out the door (still listening) and plugged the unit into my car stereo via the 2.5mm audio jack. I continued listening over the car stereo with no problems during my drive to work.
When I parked the car, I unplugged the SX66 expecting to have the audio switch back over to the speaker so I could hear the conclusion of the Podcast as I walked to the building. However, when I unplugged the unit there was complete silence. If I plugged it back in, the audio played normally through the car stereo again.
After playing around a bit, I found that except for the playing of ringtones for incoming calls, no sounds come from the speaker. The volume controls have no effect, and anytime I plug the headset in, I can hear all of the sounds normally through the headset (menu clicks, WMP, etc.).
I tried soft resets followed by more desparate hard resets. No effect. What in the world would cause the system and WMP sound to stop playing through the speaker only (headset OK), but ringtones for incoming calls play through fine? I'm confused. Is this a software or hardware problem? Anyone seen anything like this?
:?
Thanks for any suggestions,
Paul
Paul, it sounds like you have broken the audio jack socket on the unit, they have a switch type arangement in them to disable the speaker when on external sound, if a bit breaks off (which is what I suspect) then the removal of the jack plug will not re-make the connection for the audio to route back to the internal speaker - sorry to be the bearer of bad news - it needs a repair mate - Mike
Thanks for the suggestion, however it turns out this is a software problem. :lol: Specifically, it has to do with the BT patch that I was running (Cambridge Silicon Radio Ltd. BHCS, posted here: http://forum.xda-developers.com/viewtopic.php?t=36626&postdays=0&postorder=asc&start=75). It seems that if I add any BT device at all (even non-audio devices like a keyboard) and have the tray icon enabled (BTIcon.exe), then I have no sound. I'm not sure whether it's the patch, BTIcon, or a combination of both.
I removed the patch and took BTIcon.exe out of the Startup folder and everything went back to normal.
Paul
I have such problem
Sorry, I really tried to find something like this, but stuck.
Ican't solve it, and Removing BTtray - doesn't helps.
After update from
PH20B_0_B_WWE_E_BRIGH001_1.22.00_0_0_1.22.126_1.06.00_06.00
to
PH20B_0_B_WWE_E_BRIGH001_1.22.00_0_0_1.22.169_1.06.02_06.02
- same result.
Please - any ideas?
Thank you.

[Q] Co-Pilot voice output acting funny on my Desire

I am pretty new to Android and still trying to get all the grips on I need. As of now, there is one thing that really bugs me badly.
I use the device for Sat-Nav driving a lot, I have a semipermanent installetion in my car from my previous smartphones. Basically just a power feed and a 3,5mm Jack that come out of the dash panel where the device holder is mounted. I recharge plug in for recharge as needed. The audio jack goes into the device, from there to a so-called Fastmute box behind the dash which is connected to the stereo head unit (the loudspeaker output cables running away from the head unit to be specific. The Speaker lines are interrupted by the box and just pass through whatever audio is being played back by the stereo. However, once there is current on the 3,5 audio jack (i.e. speech from the SatNav) the music immediately goes mute and you can hear the turn instructions in perfect quality through the car speakers. Once the signal fromthe satnav dies down stereo music comes back.
For my taste this beats most commercial, fixed systems.
Now, since I am on Android weird stuff happens.
On a first testrun shortly after I gut the Desire (which was o2 branded stock 2.1 at that point) I noticed that I do not get any announcements through the fastmute. Checked the jack, opened the dash to check internal wiring, retried a mp3 player. It's all good on that side. The accouncements come through the device speaker, hard to hear, easy to miss a turn etc. I do not why or how, but it seems that the audio routing takes a route different from other audio. This had me pretty much meh!
Well few days later, now with a ModaCo R8 custom ROM and Froyo I was hoping for good luck and gave it another whirl. Of course, no dice. When I plug in the jack of the supplied headset (which I assume doubles as a handsfree) I get the symbol for that in the upper symbol bar. When I exchange that headset jack with the regular 3,5mm jack the symbol looks different, but still vaguel like a set of speakers.
But now here comes the completion of the mindfaq... I had the SatNav volume at about medium (so barely hearble with driving ambient noise) when the phone went and I took the call through the Bluetooth Handsfree instaalled in my car and was distracted by the call (the car came euipped with the BT Handsfree from factory, so the stereo goes to "pause" and the conversation is routed into the vehicle speakers.. A few minutes into the call I suddenly hear a perfectly well understandable, clear turn instruction hopping into the phone conservation. I was extremely intrigued and was hoping that I discovered that CoPilot can route instructions either into A2DP or more likely emulate a "call event" that results in routing the audio into the according BT profile.
However, after that singularity I tried reproducing this for a god part of an hour, driving a route that forces many instructions from the SatNav, all the while calling my own answering machine fo have an connection established.
Sorry for the lengty explanation. Questions:
1 Has anyone ran into this before? What was your solution? Bear with it, switch SatNav software, avoid listening to music in oder to not miss any turn directions?
2. Is there a hack, hidden configuration that would enable me to _force_ this audio routint into the direction of the BT Handsfree, making it think it is an incoming call?
As a fellow co-pilot user I share your frustration.
You will probably find that it's nothing as technical as it not routing to bluetooth or whatever.
Co-pilot has a nasty habit of messing with it's own volume setting when a headset is plugged in. It tends to reduce itself down to zero without notification or cause. You would try to reset the volume, but firstly, it wont go more than a third of the way up, and secondly, it will simply jump back down to zero again on it's own.
They know about this issue and their response is not to use it with a headphone jack!
It is rather annoying!!

Audio Routing issue

recently i have been experiencing an audio issue that only seems to be fix itself after a reboot. hopefully someone here can point me in the right direction for further troubleshooting/debugging/resolution.
on occasion i use the headphone jack to listen to pandora. if a call comes in during this time the pandora audio stops (as it should) however, i cannot hear the caller via the earpiece or headphone jack. the only way i can hear them is if i unplug the headphones and turn on the speakerphone. once the call is ended the audio sometimes will resume from the headphone jack, sometimes it will not. the behavior is the same even if manually exit pandora and unplug the headphones. it is also the same if an incoming call does not interrupt the pandora session.
similarly, if i am listening to pandora on the rear speaker and i plug headphones in, i get no audio in the headphones. if i unplug the headphones the audio does not return to the rear speaker.
visually, the headphone icon in the notification bar comes and goes as you would expect at all times. i am running a sprint lovers 2.2 rom. this problem only recently started, and i don't believe i had done anything to cause it like installing new apps or anything of the sort.
can anyone help me out?

[help] Headset constantly plays sound of microphone

Hello all,
Whenever I plug in a wired headphone I can hear the sound of the headset microphone. It's very annoying, especially when walking and it's windy.
Is there any known issue that would be causing this? Any troubleshooting steps?
I'm on rooted stock, headset is a rha MA750i.
Thanks!
Edit: spelling.

Earbuds defaulting to mono during calls. Can be avoided?

Hi,
I own some bluetooth headsets, which generally work ok in stereo mode wherever I listen to music/videos/Youtube.
But during calls those with a physical & electrical connection between left and right ear still deliver the caller's voice to both ears, while the earbuds (separated objects for left & right ear) default to mono and I hear the caller's voice only on one of them. Is this last behavior avoidable?
I have tried without success different pairing methods, i.e. some ear buds suggest a procedure in which one earbud should first pair to the second bud, and then this one pairs to the phone.
I have searched the net but no real answer is popping out.
Thanks, Leodp
