[Q] Question on microphine/audio output - HTC Sensation

I have been researching online about using car aux-in cable for making phone calls.
I heard that some phones work and some do not. In those cases, when it doesn't work, it means that the person in the phone cannot hear what you say, because by default the mic is muted when something is plugged in to the jack.
With HTC Sensation, does this happen? Is the phone mic muted when a headset/aux cable is plugged in to the phone? If yes, is there any workaround? What is the general solution to make phone calls via aux cable?
I heard that some people might use the griffin cable with mic, but since my aux port is located where the shifter is, I am not sure how the quality would be. Any idea?
Thanks

well, i hope this answers ur question
i have made calls/received calls via aux (when im listening to music in da car n get a phone call i dont uplug it, just answer)
i talk thru the mic normally and i hear the other person from tha car speakers.
so i guess the mic is not muted

From previous experience - though not with Sensation, as I'm all blue-tooth now, the following was true
If you plug in a normal 3.5mm TRS jack (stereo headphone / line-in / etc) the phone detects it as headphones and not headset, so the device realised there was no "in-line" mic, and used the phone's microphone itself.
A better option (which I did) was to fashion my own lead - using another HTC headset, but removing the two earphones, and soldering the cables to an in-line socket. This worked well, because I had a microphone clipped to me, with remote control for music (don't want to touch the phone when driving now, do we!!) and the stereo audio feed back to the car speakers. Cost me about £3 in total, including the second headset.
I would imagine this to be the same for the Sensation too, as all these sockets have various detection mechanisms, to make the right things happen, depending on what you connect.
Good luck, and safe driving!

How can i prevent mic turning off when headset plugged in?

If you plug in a headset in the PDA, the microphone underneath the PDA is automaticly turned off (because it assumes you have a microphone on the headset).
Is it possible to prevent this?
If i use my own head-phones without mic, i have to unplug it if the phone rings, else i can talk!
Does anyone know?
GeeZuZz,
I use an fm radio cigarette adapter to play my music through my car stereo and when my phone rings I only have to answer it and my mike does not cut out, the caller can hear me fine and I hear them through the car speakers so I know this doesnt totally answer your question but using the headphone out on mine does not cut out the mike.

Hmm... if i answere the phone with the headset plugged in, they can't hear me. But if i disconnect it, and put it slowly in, they can hear me... in other words, theres a software restriction.
Any way to override this? I'll probably never use a headset anyway (the bundled one was crap).
GeeZuZz,
It is a hardware issue. If you look at your headset's plug, you will notice that it is divided into 4 bands.
1. earth(common)
2. Right earpiece
3. left earpiece
4. mic
When inserted into the socket, the bands actually physically cut signals to the speakers and mic in the device (more like a switch).
Because your headphones stll have the same 3.5mm shape, it will also cut signal to the devices on your pda and transfers the signals to your headphones that has only 3 bands (none for mic obviously).
from my experience, i think its up to the jack that you plugged in to the device, if the jack is a stereo (has 3 black rings), the device will think that a mic is present, thus automatically disabling it. but if the jack is mono (2 ring) the mic will still be enable.
Three black rings(4 bands) mean stereo phones + mono mic. Two Black rings( 3 bands) mean stereo phones only.
Hmm... are there any way i can modify the jack, so that it will not disconnect the mic? Like putting some plastic on the piece of the jack where the mic is supposed to make the connection?

TRRS Pinouts for Desire-like proper headphones without issues of direct plugging in

Sup all would anyone have the actual TRRS pinouts for the audio jack for the desire I would like to make a up a lead that will allow me to plug an ordinary pair of headphones in using a proper TRRS jack instead of a TRS jack. thanks. There are definately issues plugging in a headphone directly or maybe it is my unit faulty?
Edited, this topic will show you the best way to connect your headphones to your desire as some people will experiance problems with pluggin in normal 3.5 jack plug headphones, this is due to the desire using a trrs socket for the microphone instead of a trs socket that normal headphones use.
pretty sure it is:
tip - left audio
ring 1 (closest to tip) - right audio
ring 2 - data of some kind
shield - ground
Hope this helps
cheers for that, im having some peeps tell me that i can just plug in an ordinary pair of headphones into the phone without any ill effects, i am concerned that i will have a problem because headphones are trs jacks and the desire has the trrs 3.5 jack. can anyone confirm any details on this for me please
nah you can use a normal TRS 3.5mm jack with no problems. I guess that when you use a normal TRS jack then shield and ring 2 on the connector are both connected to shield on the jack so it adjusts the software accordingly. But yea, no problems.
cheers for that
edited, we have since discovered that this is not the case, please read the entire topic for the correct way to connect headphones to the desire.
standard 3,5 mm (TRS) headphones DO CAUSE ISSUES
Was about to resend my HTC Desire, because it randomly called, skipped music stopped the music, FM-radio freeze etc. from the moment I connected my high-end 3,5mm headphone (TRS type: 3 contacts).
No issues with the standard headset delivered with the HTC Desire (TRRS type: 3,5mm 4 contacts).
So, you might need a TRS -> TRRS adapter.
Anyone with other experiences???
Basically what I have found is that many of the normal headphones are not working correctly because it is a trrs socket that is used. To me this would mean that normal headphones shouldnt be used, I have tried various headphones but there are definately issues with them,
The main issue I was having was as you have said above and also the base wasnt right with them
I have since bought this
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130384433476&ssPageName=STRK:MEWNX:IT
which arrive today and when I am using this in conjunction with my headphones I now have the proper base to the set and NONE of the problems I was having when i was plugging them into the phone directly......... they just didnt sound right, now using griffin smarttalk this i can definately tell the difference now especially in the base, also this unit will lower the volume and allow you to make a call automatically with built in mike, clicking it twice doesnt skip the track suggested instead it will ring the last number dialled in the phone so a bonus actually to me
the straight adapters ie trrs to trs are very nearly the same price as this if not more expensive so i would recommend this all day long to you. At £9.75 delivered bargain m8, bought late evening on the 20th arrived this morning what more can i say, but if you are having issues it is definately in my eyes because of the difference in the trrs socket to the trs socket,
the base is fantastic on this phone now, before it was terrible, now i just need an equaliser to remove some of it
When you speak of "normal headphones", are you referring to simple 3.5 TRS headphones, or headphones with a mic ?
Cause if the majority of the headphones (without mic I mean) won't properly work with the Desire, it's a major flaw according to me.
I confirm: TRS (3 contacts, without mic) do not work...
...I tried 4 different 3,5mm stereo headsets (TRS type, 3 pole, without mic). NONE of them worked correctly (phenomenons as described above).
When you plug a 3 pole TRS headphone in the Desire 4 pole TRRS headphone output, a short circuit is generated between the first 2 internal contacts (seen from connector input: ground + control line).
I suspect that the Desire firmware cannot detect/handle this situation, and so it causes random actions (prev, next, call numbers, stop, play, ....)
I suspect that this issue could be solved with a firmware upgrade....
there is no way they would release hardware with a 3.5mm socket that you cant plug a 3.5mm jack into right? the firmware does detect when you use a TRS instead of a TRRS. You get a different icon on your notification bar for each of them. As ive said before my AKG's have worked perfectly so far and have shown none of the problems listed above.
This afternoon I quickly tested my Seinheiser PX100 headphones with a friend's desire and the Htc music player.
It worked flawlessly. Volume was good and it didn't play/pause/skipped tracks.
As I said it was a really quick test so I can't say for sure that everything's was okay.
Nonetheless apparently a lot of people experienced problems with numerous headphones. To me it's really a shame you can't even plug ANY 3.5mm jack headphones with the desire ...
I hope a software update could fix this.
I also had this problem when connecting my Desire to my car radio using an standard 3.5mm AUX cable. Will this cable solve my problem or will my car radio not be able to recognize a 4 pole cable?
http://cgi.ebay.nl/3-5mm-Male-TRRS-...erAccess_RL&hash=item5d28c530c1#ht_1252wt_939
I think this might be an issue of certain cables not making a full connection due to the shape of the case surrounding the socket. I had no problems with my headphones, sound was good and loud enough although I could see how it might not be loud enough for some.
I did start having issues when I plugged the aux lead in my car into the phone. The lead has a large shroud that obstructed the plug from being plugged all the way in. This gave the same problems as described in other posts, skipping tracks and also crashing the music software at one point.
I replaced the lead with another that had a better fit and the problems went away but I did notice when I leaned against the lead while it was playing music in my car it started skipping track again.
I wonder what HTC have to say about this....

I solved those problems with this lead- i dont think the one your showing will work for you
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=220593400305
they come from china etc however only 5 days to arrive from ordering.
and I now enjoy trouble free music. I also have ordered the Griffin Smart Talk so i can listen to my headphones and be able to answer the phone as well however I didnt want to use it for plugging into a car stereo etc etc so i wanted a straight lead conversion.
Just a quick warning the first lead i ordered from this person was faulty, however i had also ordered 3 other leads from the same person as an after thought which were all perfect.. as they are only pennies it is worth ordering one or two spare for redundancy purposes. I decided to order 3 as backups more in case i broke one and the person stopped selling them etc etc
These leads will allow you to connect the htc to any other source including external speakers which didnt work when putting them in normally but did work when i used this cable in conjunction with it.
this cable is a trrs to trs jack plug and is used to convert a 4 pin socket to a 3 pin socket jack plug.
I've been using a pair of JVC Gummy Air on my Desire since I got it, not a single problem.

External microphone for 3.5mm audiojack.

Hey!
Anyone knows if it's possible to connect a external microphone in the 3.5mm jack. Would be nice to be able to plug in a better microphone when recording music shows etc. Shouldnt it be possible since you can speak through the htc-headset?
I don't think that you can plug a mic in it, this jack is "way-out" only, not "in"...
At least i never tried, but i guess it's how it works (if anyone can confirm this or prove me wrong ).
It's a 4 pin 3.5mm TRRS connector. It has a mic connector built in as well as the audio and ground.
I don't know if you can get a microphone with that specific connector, look it up and see... but it would be pretty easy to make your own connector if you cannibalise a headset or something like that and then connect whatever mic you wanted to that.
Not sure about the quality, but dealextreme sku.20714 seems like to fit your description.
I bought one of these some time ago to connect my Klipsch headphones.
http://cgi.ebay.co.uk/3-5mm-Headpho...GS-/280544944694?pt=UK_Mobiles_Accessories_RL
It is still recognised as a headset even when there are no headphones plugged into it.
So the quality for what you want is probably poor BUT it does prove that it can be done.
Perhaps one of these PLUS a good quality mic PLUS a soldering iron is the answer

[Q] Galaxy S calls using phone's mic and head phones

Is there anyway I can talk through the phone's mic and listen with ordinary head phones?
I can do this with pretty much any recent Nokia or iPhone, but the i9000 just seems to ignore normal headphones completely when answering a call.
This looks more like a software thing.
some phones doesn't work like that, you can listen but not talk when using the 3.5mm headphone (without mic)
like my old Palm Treo phones you can only use it unplug, or plug but then your headset will need to have a mic, else it wont work.
the next best thing is Stereo Bluetooth, they all come with a Mic
Not even that much
That's the thing, on the Galaxy S can't even "listen" to the phone call using headphones.
check this topic, some people already found out several models that works with SGS

Thank you for your help, but what I'd really like to do is connect Galaxy to my car stereo's 3.5mm input and answer the calls using the car speakers.
I know that if I used a Nokia Mic adapter, it should work, but CRAP!
This is a way too expensive phone not to do that without the need for an adapter.
I have faith someone will come up with a way to bypass Samsung's stupidity and just leave the audio jack active when in a call.
Also, if I want to use my Sennheiser HD headphones, I can't without putting a crappy adapter between it and the telephone.
if it's for the car, then just get bluetooth for the car, it's by far the easiest way
The easiest way is a 25cent cable
The easiest way is a 25cent cable that does not eat up my battery like BT.
Again, I thank you for your help, but the perfect world would be someone to flip a switch in the phone's software and just make sound come out of it.
You are right; I also had my Hero connected with the 3.5mm cable to my car stereo and when I received a call, I switched my car to AUX and picked up the call, presto! Sound was routed through speakers and mic would pick up my voice perfectly.
Now with my new SGS it just doesn't work! I must leave the cable disconnected and switch the phone speaker mode on to be able to talk. How sh*t is that?
So here I was excited about a 3.5mm jack. Oh well. Just shows to go ya, size doesn't matter.

Hey,
Can you please elaborate on that cable wiring? or where to purchase etc?
I think the best thing is have an adapter with a mic and a female headphones socket to which you connect ANY headphones.
Just a followup on this, my old n95 adapter works perfect.

it's kinda weird. it works and it doesn't.
i have a jvc in-ear earphones and skullcandy lowrider headphone.
when receiving a call with my jvc, audio switches back to the phone's speaker and phone mic won't work unless i unplug the jvc.
with the skullcandy lowriders, call is routed to headphones and phone mic work perfectly.
note: neither of these pairs have an in-line mic, so the mic i am referring to is the one on the phone.

I am experiencing the same problem, which is very annoying and might keep me from buying Samsung again if they don't provide a fix...

It weird indeed.
I tested an iPhone stock headset (which has the exact same jack as the galaxy S headset, at least visually), and the calls are not ROUTED through the headphones !
A possible explanation for this is that the phone monitors the headphone's impedance: if the impedance is different from the one of the stock headset, then call sound is routed to the phone speaker.
I'm really hoping some developers will come up with a fix or a custom ROM to fix this issue.
i'll post the specs of both headphones for scrutiny when i grt home.
one thing i can day though is that my jvc has 10mm drivers and my lowrider has 40mm drivers. does that even matter?
i'm also gonna try to see what happens of i use my bro's skullcandy asym in-ears.
Sent from my GT-I9000 using XDA App
Any news about this issue?
I am about to throw this phone against the wall because oh this.... Damn!!!!
If there are things which should not be considered "as features", this is one of those...
sorry but it took me a while. first, here are the specs:
skullcandy lowrider
driver: 40mm
freq response: 18 Hz - 20 kHz
impedance: 32 Ohms
Max Input Power: 400mW
jvc HA-FXC80
Driver Unit: 0.23"(5.8mm)
Magnet type: Neodymium
Frequency Response: 8HZ - 25KHz
Impedance: 16ohms
Sensitivity: 103dB/1mW
Max Input Power: 150mW(IEC)
skullcandy asym
Driver Unit: 13mm
Frequency Response: 18Hz - 20kHz
Impedance: 32 ohms
Max Input Power: 30mW
and one more thing i tried...
x-mini max speakers
Drivers: 40mm
Frequency response: 230HZ -18KHZ
Sensitivity: 86db/1mW
Out of all the four, the calls would only route to the skullcandy lowrider. At first I though it might have been driver size, that's why i threw in the x-mini max for the test. looks like there's another factor that's causing this anomaly.
It's definitely soft problem! Because in Nimbuzz software, if you use Nimbuzz-out (same as Skype-out) and i had phone connected to car with 3.5 mm jack, sound went to car stereo, and i was talking using samsung mic. So if they could realize this "feature", why samsung couldn't?

Noise using with the car charger

I'm using the Desire as music player in mine auto. It's connected via aux to the stereo and works well, but when I connect the usb car charger begin a loud noise...that's connected directly with the car motor, because more high are the rpm and more is loud this noise
What I can do for solve this problem?
Same thing here, it has always been this way even with my old Nokias, HTCs, MP3 players... it's an interference you can't suppress, while charging and using an audio cable to AUX IN.
ps. I'd really like to be proven wrong by someone else who finds a solution for me, either!
By the way, how do you handle hands-free? You hear callers voices but you have no mic to speak in so they can't hear you.
Do you know any way to use Desire's mic as input AND 3.5mm-audio-out as output?
You need a noise filter! Google "car stereo noise filter", thye're cheap.
I dont get this, but I used to in my old car.
Its easy, you need a noise supressor on the line - what you are hearing is alternator whine (a whine that changes in pitch with the RPM speed on the car).
