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.
Re: TRRS Pinouts for Desire
I've used some headphones, and 2 different aux connector for the cars and all 3 work absolutely perfectly. No issues at all.

Hi,
Does anyone know if there is a sound dock available for HTC Desire or Micro USB? I want one like those for Iphone:

this is not possible through usb, because the usb prt of the desire doesn't have athe audio out pins for some stupid reason. The only way to do this is through the the jack plug.

Hi Lukzke....do you know if this is possible, (playing out through the ear phone jack plug)?
I did try this using a camera lead that was 3.5mm plug to two rca plugs, into my home amp's aux in ports. I had to turn the amp volume up very high to get any sound out, and then it started skipping tracks and generally behaving badly, so i disconnected. (There may be a better lead out there).
Would really love a solution so that I can stick a finger up to the ipeople!

just did this the other night with a 3.5mm->3.5mm lead. the only way that it MAY have done that if somehow it interfered with the control lines (used when when you use the stock earbuds).
try a different cable, that should fix it.

I have an FM transmitter in my car that I plug into my 3.5mm jack; and I've noticed once or twice that when jamming the connector in at a funny angle without paying much attention, that the phone comes up with the "headset" icon instead of the "headphones" icon. Unplugging it and plugging it in again always solves the issue, though. I think it just happens due to accidentally making contact with the microphone/control contacts.

yes, a new simple lead fixed it....a Connexia 3.5mm G+ model....quite cheap and has worked all day without skipping and the volume levels are ok on my Marantz amp.
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).

Doens't exist a car charger that includes this "ground loop isolator"?
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!
Im asking all you guys to help me find best methods, settings, and tweaks to get the best possible audio recordings on my SGS4G. Im asking this not only from the devs here but from all the audiophiles as well.
The reason im starting this thread is that my partners iphone 4 just with the built in mic and camera has produced video and audio recordings 10x better then what this phone has. With great dynamic quality and no distortion or anything. I need broadcast quality recordings for this project to succeed. If i am not able to do so im either going to have to try to clone the SIM card and get a used iphone 3GS just for field work, or give up this phone and switch to an iphone 4. Either of which i really dont want to do. If part of the solution is to dump GB and go back to Froyo, then so be it.
Heres what i got:
1. Highly modded SGS4G with Valhalla 1.3.2, Launcher Pro Plus
2. 32GB class 4 Sandisk card
3. UV using the settings in the ICBINB therad (i tried some lower ones dsexton posted, but they made the phone very unstable)
4. Voodoo Plus sound app
5. i-Microphone (sound was horrible, more on this later) http://www.amazon.com/o/ASIN/B004XC6KHS/ref=nosim/betteraddons-20
6. Sennheiser E835 with XLR to 3.5 mono minijack adapter
7. Rec Forge and Hi-Q MP3 recorder (trying both, if you know of any with more features please share)
First off, im concerned that the custom ROM, kernal, and UV settings may be affecting quality. Any input on this would be appreciated. Ive tried OC, but 1.2ghz was never stable and 1.3ghz drained the battery too much.
I first off was looking for a good solution for face to face interviews, i found the i-mic (link above) to have good reviews, but when i bought it and tried it out, the recordings were horrible! Like someone was rubbing their fingers over the mic when talking. I tried gain adjustments in Voodoo and the recording apps im trying out, but nothing helped.
I plugged in my new Sennheiser using a XLR to RCA cable, with a RCA to mini jack adapter. The sound is A LOT better, but still there is a humming over the recordings, and they just do not have the dynamic quality that im hearing with the iphone recordings.
Are there any equalizer and sound processing apps for commercial or professional audio work out there?
Im at a wall here, any help to these issues would be greatly appreciated. Thanks in advance.
It's hard to tell exactly without seeing your set-up but it sounds like you have the following issue.
The XLR is a balanced connector. When you go to an RCA you are dropping down to an unbalanced connector and losing your ground. That is where the hum would stem from.
To eliminate the hum you would need a cable that converts directly from your balanced XLR to a balanced T/R/S (Tip, Ring Sleeve) mini jack. This mini jack has 3 separate contact points, separated by two plastic bands on the plug instead of one.
Ideally for broadcast quality you would need to run your Sennheiser E835 into some sort of mixer with a mic preamp. Then run the line level out from the mixer to the SGS4G. Your recordings would be crystal clear at this point.
I don't believe your issue is with the SGS4G hardware. I use the camcorder with the built in mic all the time and the audio quality is fine.
Hope this helps.
you don't need a balanced connection unless you are talking about long mic cables like over 5 feet long and equipment that is plugged into AC current. Balanced connections are for getting rid of the 60 cycle AC hum, basically.
If I was trying to record using a 4g I would think about using the usb input and some kind of analog to digital converter box. Here is a cheap one -- $25 behringer UCA 202 providing 2 RCA inputs-- it's about the size of a phone. and supposed to work on linux without drivers so maybe it will work on android. I have three of them and use them for laptops. They're pretty good at eliminating noise. I just don't know if the phone has enough power to operate the unit. You need a female to female standard usb adapter to connect the data cable to the converter and something to adapt a (short) mic cable to an RCA port. if it works you can use a dynamic mic like a AKG or Shure or some smaller dynamic mic and will get better recordings than anything built into any phone. It will be a little bit bulky but you'll still be able to fit the whole thing in your pocket. I should try it with my phone and see if it works but I need to get the female to female adapter. if the phone recognizes the UCA202 it should work just fine with a Sennheiser E835. My girlfriend uses a Sennheiser MD-431 for recording songs with her laptop and one of those units.
They also have usb mic adapters at places like guitar center. If you have the female to female USB connector you can take your 4g to guitar center or wherever and try their mics out before you buy anything.
@Nazcalito....great advice, I guess spending all my time on a control room board I hear the word 'hum' and immediately think 'where's the dirty gear, who's missing a direct box.' Haven't used a cable under 10ft in as many years. I'd be very interested to know if someone could get the USB audio/phone rig cooking on or s4g, that would be sweet.

Thanks for all the responses, ive been playing around with this and i do think the hardware is the biggest issue. I noticed the issue im having is that the built in mic is not turning off when using an external one. When using the external mic, i can tap over the back mic and get the feedback from it as well as the audio from the external mic.
Now the built in 3.5mm jack is a four contact TRRS plug, the RCA to minijack adapter is only two contacts. This would explain why the little plug in mic was getting all the feedback. Though even that mini i-mic was a TRRS plug like the headset thats included with the SGS4G. Why is the built in mic not turning off?
Nazcalito, your suggestion of the USB audio interface may work, i did consider a microphone with a USB connection, though i could not find any accounts of this working by simply plugging the mic in to the phone with a USB to microUSB adapter, and didnt want to take the chance. Though i like the converter box you showed a pic of, i could just velcro it to the back of the phone to make a mobile unit. I'll probably buy one if youre able to confirm it works. Again would i have the same issue with the internal mic not turning off when using this?
One thing i ordered was something called the headset buddy, its a TRRS male plug that splits into two separate minijacks for headphone and microphone. Im hoping this will solve the problem.
http://www.amazon.com/o/ASIN/B002SK66OY/ref=nosim/betteraddons-20
Another concern is the pinout of the SGS4G. Ive found diagrams for the i9000 that shows the mic and ground contacts swapped, and others with the regular mic as the last pin that claim they are for the Galaxy S2 and SGS4G. Anyone can confirm? This might explain the internal mic staying on.
http://pinoutsguide.com/CellularPhones-P-W/samsung_galaxy_headset_pinout.shtml
http://pinoutsguide.com/HeadsetsHeadphones/samsung_i9100_headset_pinout.shtml
As well should i have all the options in Voodoo turned on for this?
Ya know, i wish i didnt order the headset buddy already, i would have tried this:

The adapter did not help, the internal mic is still staying on.
That's not good. I have a similar problem occasionally with headphones not muting the speaker when used...I have to wiggle the plug a little until it mutes. The contacts are definitely a little touchy.

Can anyone with a stock froyo SGS4G try plugging in an external mic and see if that solves it?
