HTC Desire - USB audio output possible

Hi Devs,
first of all, sorry for starting a new thread, but searched the forum and didn't find exactly that.
Like I've read, there is no audio over USB support built-in to our mighty Desire.
I tried a few different microUSB to 3.5mm jack adapters from ebay - even one declared as for HTC Desire. Checked the usb-pins-assignment also and it seems that HTC hasn't built in (or turned off) that function in opposite to some other manufacturers.
So will it be possible to write a rom or a kernel, that'll support that?
If it is possible, I would appreciate a few hints what I'll have to do, to get this thing working!
Thanks in advance!

Can I know why you need that? Is it for A/V out?

Its not possible to send analog audio signal over the usb since its a standard usb plug. Only the old htc phones with extUSB had audio, but its was a bigger plug with more pins.
On that note i dont get why you want to get audio from there, when theres a nice 3.5mm jack socket on the top of the phone.

Thanks for your quick answers!
Yes, since there are no music docks for desire I built my own and it has to be possible, other phones with microUSB have that function - why not ours?
I know the old extUSB plug from my magic, there it is no problem. But there must be a way to get this working! I think it is only a software and/or driver issue.
If you'll get a music dock you'll have to plugin the phone + jack everytime? ? ? Look on ebay there are a few universal docks over microUSB, but not working for the nearly best and most sold android phone on market?
Pls give me some hints if there is a way to do that - everything is possible!

Umm, well not really. Because who says that the USB port of your phone is connected the right way internally to actually SEND data over the cable/dock.
I have no idea on how to do it. Thats just what I think, but with Android, a LOT is possible

YEAH IT IS!
On Nexus one they built in extra pins for docking and audio over that works like a charm.
I'm having a few adapters microUSB to 3.5mm jack for Motorola,Samsung,Nokia...phones from ebay, but not one reaction from Desire
Maybe the adapter for Desire needs a Digital-to-analog converter to get analog audio out of the microUSB port.
But no technical details over that from HTC - does anyone know more about the microUSB connections on our Desire? Tried to get a technical manual for Desire, but no chance on google...
If there is no other solution, I'll have to disassemble my expensive Desire to get a view on connections and maybe some hints which IC is managing the microUSB.
Does any dev know what would be possible by modding a kernel or rom?
Thanks in advance!

im also looking for something like this, though i want digital-audio out. for example in my car, plug and play so i get spotify from my usb to my stereo and able to control spotify from my stereo. there is no problem for this if you use iphone, though id like to be able to do it on my htc.
any solution?

Ability to stream out the audio through USB would be something nice to have.

There's a guide online on how to splice a USB and 3.5mm cable to the Apple USB cord so that you can charge and play audio on ipod accessories, as long as you don't mind having USB and audio plugged in at the same time. http://www.erwanmace.com/2012/07/ipod-dock-android/

What happened to the TV-OUT ?

One of the most things that amazed me in Galaxy S II .Is the ability to output to HD/SD screens but today i've bought a 3.5m to RCA cable then plugged it in but there was no image and no option for TV-OUT !
So where is the TV-OUT exactly ?

Really, you did what?
I don't know how you could expect a video signal from an audio port. The thing you are looking for is the MHL Adapter (USB to HDMI) which isn't on the market right now (June most likely).

well actually the first sgs had tv-out from the 3.5mm port, as well as some nokia models, my dv cam has the same so its not impossible, but i find it strange that more people don't know that the sgs2 has the MHL adapter, see threads like this popping up all over

I'm surprised people are largely unaware of this too.
I really need the MHL cable, I used my Nokia 3.5mm TV Out cable a lot with my SGSI, really looking forward to being able to output HD content with the SGSII !!!

MHL was added, so tv out was removed.
photo editor was added, so adjustable saturation, sharpness, and brightness was removed.
video editor was added, so ability to pause while recording video was removed.
Thats the Wonder of Samsung~

Does anyone know if a non-samsung specific MHL cable would work with the SGS2, same as generic USB on the go cables work ok?

and yes, with the release of netflix today, and newly discovered "TV Shows Stream" app, i have to use my old sgs..
i wonder if software can fix this, or if hardware is missing.. someone should look into this

Its a standard, so yes, a non-Samsung one should work (only reservation for me is that GSMarena say that this one only works when a charging USB cable is connected to the adapter, so if a non-Samsung one didn't have a charging input it may not work).

MHL is just another way of saying HDMI-out !
I'm asking about the SD output that uses RCA connectors to plug into TVs.

Yep, I know what you're asking, it doesn't work (several of us have tried).

your one of those many people who don't really know what they are buying when they buy it, always a mistake. You need to do your homework before you waste any more money my friend.
Its all about the MHL port dude....

thats not true at all.. there were no reviews of this phone before it came out, and thats like saying 'oh you expected mp3 support?' yes ofc we did, isn't it a given?
will mhl be able to interact with rca at all? or are all tvs pre 2010 useless now?

I believe that person was discredited later though.
In any case they are mistaken, because myself and several others have confirmed this is NOT working with the SGSII.

Sorry, wrong post

There has been plenty of info floating around about this phone prior to release and on release day, if I and plenty of other people new about this and you didnt then as I said before you didnt do your homework
the MHL port will work with all tv's with HDMI ports, however it will only charge your phone via this port with new TV's with MHL compatible ports.

@ stoolzo
what about those TV'S with no HDMI ports.........???

Join the 21st century and buy one that has?
seriouslly hdmi has been out for years and it is the norm on all TV's. That would be like having an argument about scart if your TVis 20 odd years old?

How about this one :

I've seen them in the stores in the UK for about £ 180.00 (Currys, Comet, etc)
Sound quality is awesome, and I'm probably gonna get one at some stage. Charges the phone via USB but audio is either via Bluetooth or All share WiFi.

I'm waiting for a dock with usb audio. I could put up with Bluetooth, but won't bother plugging in to the headphone jack. But like I said I think I will wait, I hope there will be a few options by Christmas.

Moto-Z Play Type-C Headphones

hello.does moto z play supporting usb c headphones?anyone tried that ?

Yes it does support USB-C headphones. The only ones I have gotten to work are USB headphones without a microphone which seems to be harder to find online now.
