Audio via USB

Hi all,
has anyone flashed the Prophet with the TouchFLO rom like PDAViet 4.0.0.0.6 or similar and have used USB stereo headphone?
The HTC TouchFLO uses USB stereo headphone as standard.

no the usb connector in some htc devices just carry wireing for normal analog audio
it dont mean they can use real usb headsets
just headsets which use the same connector
or one can get a converter from the usb analog audio connector in 1 end and normal minijack in the other

The headphone-through-USB will probably be hardware based, and so no amount of flashing will bring it to our Prophets.

Adapter

USB adapter. I just love the Elf phone.The only things I am disappointed in is that I cannot plug in a set of external speakers. I cannot plug in to the charger whilst watching a film as I need the socket for the headphones...
Does anyone know of an adapter to enable me to do this please? I could get one made up from the diagram, however I would prefer to buy a custom made one.

maybe something like this?

The Elf has only a USB socket, nothing else... No phono or whatever they call it... For me this is the only fault with a superb little phone.
Thanks anyway.

dont know about the elf but all other newer htc devices have a special usb connector which also carry audio
if your device came with a headset then yours do too
as they device dont support usb host so it cant use any usb devices
nm just saw my link was wrong :S

3Way USB adapter for HTC Touch/Elf
There is in fact a 3 way adapter available. I found it after a bit of a search. For some reason some of you seemed to think I was looking for a headset. The USB socket on the HTC Touch does not allow you to use anything else other than the supplied USB headset. however I want to use a set of Sony speakers for the sound to play MP3's and as I like to watch films in bed through ORB I like to be able to charge the phone at the same time. The process uses a lot of battery power.
The adapter I found has a stereo jack socket and 2 USB sockets the same as the one on the phone. So now I can plug in my head set and charger or charger and speakers in any form I choose.
If anyone else is interested here is a link where you can buy one for about £12.00 which includes postage: http://www.elitextreme.com/htcto31ad.html
The pictures show what I was talking about...

Oooops! sorry Rudegar I missed your post for it already.

HTC 3 way adapter
No Expansis do not carry one. The link I left earlier does. I have mine now. It is exactly what I wanted. Cost me £12.95. Well worth it.

OK, so this is *almost* what I'm looking for:

Does anyone know where to get an 11pin to 3.5mm adapter? One that *only* has a 3.5mm stereo output instead of having stereo+usb output?
Thanks.

Thanks for the find, but will it work even if it's for the TyTN and not specifically for the Touch?
And is it stereo as opposed to just mono?

i would asume that htc dont change the wireing of their miniusb connector flavour with each device it would serve no purpos and would cost alot for htc
i would asume that if stereo is in the miniusb connector when used for normal wired headset it would be using that converter
as it would serve no purpos for the converter to add the eletronics it would require to just take 1 channel and spit it in 2 without lowering the the volume to ½ because of the impedanc

Mini USB to 3.5mm audio ???

I have just got delivery of my Asus P320 Windows smartphone. But unfortunatly i have discovered that there is no 3.5 mm or 2.5 mm headphone jack on it. I am wondering if there are any 5pin Mini USB to 3.5mm or 2.5mm headphone adapters, If not, is there anything i could use with windows mobile 6.1 to get music through bluetooth to a small module which I could connect a 3.5mm headphone jeack to. Thanks for your help.

yes their is a usb to headphone jack you can buy
.... never seen a small module but you can stream your bluetooth to a bluetooth headset

Yeah I already have an expensive set of New sennheiser headphones which i do not plan to replace. they are wired so If i was to go the bluetooth route it would be to get a small module which I can connect a 3.5mm audio plug into to convert it to bluetooth signals to my phone.
But you say You have seen 5pin Mini USB adapters, Any Idea where you saw them and where i can get it from,,,, specifically?

I am using this one
Works great! Just plug in any 3.5mm headset and you even have call handling and mic on it!

hi,is there anything like that ,that would work on iPAQ 614c?

miniUSB dont carry audio
it's like normal usb a serial digital data transfer std.
thats why htc have extUSB which is miniUSB with analog audio in the extre wires
pc headsets or speakers which use usb are really external audiocards which transfer the
digital data into analog sound
as far as I know no device can use en external audiocard unless it support usbHost which pretty few wmobiles seem to do

ok,thanks,then i'll have to keep on "enjoying" the music with headphones i got with device heh

Just arch on ebay for a "mini usb to 3.5 jack and it will come up with loads all min haved worked with my tytn and tytn 2 all apart the one i bought which said it fits a motorola razor!!!
Also i have not payed more than about £7 inc postage so far.
Happy hunting.

HI I have the same problem. I have an I-mate Ultimate 8150, I bought it used and when I opend the box I realised that the were no head set or charger.
I'm seeking the polish internet for a adapter 11 pin miniusb - jack 3.5 with no results. I bought an adapter for motorola v3 and it isn't working just like a head set for motorola K1 on miniusb.
I-mate 8150 is very similar to XDA Flame and I think that in those models the sound pins are different do the in the HTC models.
I am looking for some 11 pin miniusb schema (the socket is also used to charge and comunicate with computer).
I've seen an adapter on http://www.imatephonestore.com/accessoryDetail.asp?accMDL=AUDIO_CONVRTR
but i think that the price is too high for such a thing.
Maybe some one knew how to make this adapter or how to remake the motorola k1 headset to work on I-mate 8150
Plaese help me I don't now what else to do thanks

get 11 pin to 3.5 mm
even iam using htc
nd in htc we also have 11 pin jack
i saw one very good converter on :- http://www.amazon.com/Touch-3-5mm-S...tionId=1XM1P73VXKBX6ZQPKN02/mixi-20/ref=nosim
however instead of buying that wt i did i bought a erricsson bluetooth enabled headphones they are cool nd free from entangles nd best part is that even my bluetooth have 3.5 mm jack so i can connect with my car.

Well I bought 2 of 11 pin to 3.5 mm headset adaptor convertor for HTC. Though both are working same but little difference make them very unique. First one is Stereo Converter 11pins to 3.5mm adaptor which simply let me to use my Blackberry curve headset with G1. Other one is cool coz it comes with microphone as well answer switch. I am now using my 3.5 mm headset with G1 and also talking and answering from the same headset converter. Its really cool check this our http://www.fommy.com/accessories.as...obile+G1&cat=Headsets&subCat=Headset+Adapters

Cool I just order one for me the Streo headset adaptor with microphone and answer switch. Along with this I also got 3 in 1 USB adaptor. This one comes with 3 ports to connect 3.5 mm headset jack, 11pins to 11pins HTC adapter and USB connected that can be use to sync or charge G1

11pin is no good, Im looking for the 5pin usb which is on the Asus P320, are there any atall, I have already tried buying a motorola one which has the right connectors but does not transmit any sound.

I have the same phone and looking for the same converter
r there any converters specially available for this phone out yet?

I have AKG's and so youre telling me I cant use them even If I get the USB to audio jack adapter? Also In our store this guy connects his phone to the stereo system in the store with a mini audio (banana plug I think) to the system and plays his music of his phone..can the TYTNII do the same?
BTW, even if I could use the AKG headphones it probably would sound so loud as these are high ohms headphones AKG 240MKII..right? any cheap micro sized headphone amps around?

The mini USB port in asus p320 is actually a 10 pin port (5 on top and 5 on bottom). out of them 5 pins are used for audio and microphone. And others are for USB. Hope this information will be useful for searching 10 pin mini USB to 3.5 mm audio.

I've been using this for my xv6900. It works great.

[Q] Audio line-out for Galaxy Nexus

Hello all ,
Is there a way to get an audio line-out from the Galaxy Nexus, either using an adapter or a docking station? I'm not looking for a solution like the one offered by the Samsung Galaxy S2's car dock (which streams bluetooth audio from the phone to the dock, then the dock turns the bluetooth streaming to analog audio through a 3.5mm port) but rather something like an adapter for the MHL port or from the docking station.
Appreciate all the help!

The obvious solution (at least to me) is to plug into the headphone jack. You could also use either the media dock or MHL adapter in conjunction with an HDMI-to-analog adapter such as the one linked below:
http://www.amazon.com/HDMI-RCA-comp...OQPU/ref=sr_1_2?ie=UTF8&qid=1321905031&sr=8-2

He's asking for a line out solution because it will bypass the internal headphone amp that is utilized when the 3.5mm port is used. If you're plugging the phone into speakers or a sound system that way you'll get much better sound.

If the mhl -> HDMI cable adapter carries both audio and video, you could use an hdmi breakout adapter to split the digital audio. It depends on the HDMI output capabilities of the phone and the acceptability of digital audio for your needs.
Edit: would no doubt be a cumbersome solution. It all comes down to your usage scenario for the output.

Thank you vespoid, ardabey.
What OJ in Compton said, I'm looking to bypass the internal headphone amp, not sure if there are any details on the car dock or desk dock, I hope 3rd party manufacturers come up with something, any solutions are welcome.

Never thought about this, but a contactless dock with HDMI out directly to the AMP = audio bliss. Thanks to the forum for letting me see the obvious

Bumping this thread...has anyone successfully done this? I want line out audio for my car's 3.5mm AUX input - had it with my ipod and it sounded much better than through the headphone jack, as well the convenience of not having to maintain two volumes.
Hoping the official car dock that uses the 3 pin connector and has a 3.5 out would do this, but I'm worried it will just use BT to transmit the audio to the dock like I read the Nexus One dock did.

I wish too that the NG had line level out.
I think it's a limitation of the hardware. I think Apple is the online one that really uses line level out via it's dock connector.
I hope someday Google will use some sort of line level out on their reference hardware or built support directly into a newer OS.
I remember my old Dell DJ had line level out. Soooooo much better.

There is nothing wrong with the 3.5mm output sound quality wise.
Trying to drive headphone-like impedance (lower) with a line out isn't the best idea, but driving higher impedance inputs like your car deck isn't that bad as long as you let the amps do the "work" of boosting the volume and not your phone. While not optimal, the decrease in sound quality shouldn't be very noticeable.
The main advantage of the digital audio though USB (what apple does) IMO is that it eliminates the need to have both the USB plugged in to charge and the 3.5 mm cord for audio. It also allows song data to be shared and device control from the speaker/head unit. Good setups will recognize most android devices as mass USB storage and provide the same functionality, but I'm not sure how the MTS on the GN will affect this.

I would wait and see how the audio quality is from the dock. Even if it is bluetooth, the audio quality may not be that bad.

The problem is, that if the head unit supports MTP then yes it can read the device like mass-storage, thats fine, but it doesn't allow you to stream media from radio apps, youtube and turn-by-turn directions from gps, this is what we are looking for...
technically it's not sending analog audio output through the USB, its just reading the stored media on the phone.
I have read that samsung phones are able to accomplish sending analog audio through the USB while charging, with the correct resistance values (adapter) or possibly with software pointing the audio in that direction (for example code build into the framework/API)
this is one major thing that Android lacks over iPhone, this problem should be addressed ASAP. I'm hoping CM9 might be able to find a solution for this.

I agree, i hope they fix this soon toi. It would make the development of accessories much easier for all android phones. Seems like a no brainer but I guess Google has other priorities...

Just starred this, if the hardware is able to do that I find it completely stupid that they do not allow it.
Smartphones audio amps are not exactly famous for being top-quality so having this possibility would be great.

Thanks. The lack of this feature is ridiculous/mind-boggling/suprising.

Well, if you were waiting for the card dock to solve your problems... it doesn't. Plugging into the dock's "line out" gets you amp driven sound. I really do not understand why this is such an issue for Android. When I plug somoething into my 3 year old Nokia smartphone a window pops up for me to choose headphones, headset or line out. Why can't ICS offer the option and if in the car dock, default to line out? A USB solution is not going to help if you are using the car dock.

Which if I understand correctly uses Bluetooth to transmit compressed audio from the phone to the dock, then delivers it through the 3.5mm jack. Why not just have a digital signal go through the USB port!?

actually the pogo pin transfers the digitial audio and the dock decodes it into analog to the 3.5mm output

[Q] 3.5mm to standard USB for car stereo music? [RESOLVED - IT'S NOT POSSIBLE]

Anyone know if I can take a 3.5mm to USB cable. Plug the 3.5mm end into my headphone jack on the phone. Then plug the USB end into the USB port on my car stereo, and listen to music that way?
I know there are other ways of listening to music, but I need the answer to this particular question for something more complicated that I'm researching.

No, can't be done.
And the only way to connect to car is with SGS3 Easy UMS.

Our phone's 3.5mm headphone jack is TRS (headphone) or TRRS (headphone and mic) only. Devices that use the 3.5mm port as a USB port specifically state that and only support charging and USB data (to put music on the device). You would need a separate device to convert the analog audio out of the 3.5mm to digital and stream it over USB and even then your car's headunit would have to support streaming digital audio over USB. Our phones do support streaming digital audio (USB audio host capability) out the micro USB cable though.

Bummer, okay thanks guys.
I think I posted in the wrong forum also. Sorry about that.

thx
