Hey DX hardware gurus... - Droid X General

Is it possible to reroute the headphone jack via software so it behaves as line in?
Sent from my DROIDX using XDA App

I would think it is possible because there are adapters that plug into the headphone jack that people use to charge credit cards.

Ummm, doesn't the current setup support that already?
This one for instance,
http://www.thinkdroidxaccessories.com/motorola-droid-x-mb810-wired-headsets-3117.html
seems to be Mono sound + Mic; but I believe the Dx supports Stereo sound + Mic if you have the right Plug/cables.
Should just be a matter of making/finding the correct cable to work as a line in.
A little more information on what you are looking to do would be more helpful, recording from a wired input rather than built in microphones? Use your phone as a amplifier/speaker?

Well, I've been playin with 4-tracks lite and thought how nice it would be to be able to record some loops from another device. Then I got to thinkin about midi I/O as well thru the hdmi port or maybe the power port (hadn't asked that question yet
..thought I'd start small). Stereo isn't really necessary ...mono with panning is fine. I was toying with the concept of developing a nicely appointed music workstation app.
I have these brilliant ideas that turn into silly ideas after a nights sleep and the realization that software development will consume all my songwriter /production time. So thanks for the the tips...I was not aware of the mic portion of the hheadset...obviously proof of concept.

Tv out?

Has anyone tried to use tv out on the fascinate? Its the main reason I got the phone only to find out it may not have this function like the other galaxy s phones. Does anyone have a cord to try it with?

I would but damn, 50 bucks for the Micro USB to HDMI cable from samsung.
I'm more interested in the rca out from the headphone jack actually

Tried earlier with a Zune video cable but no luck. May be the cable however, can't ring it out to confirm until Monday.
Any links to confirm pinout of the headphone connector on the Fascinate in the meantime?
I saw a video earlier today showing a prevew of the 3.5mm jack to rca on the international galaxy s, and it was enabled through settings > sound & display, but looking at my phone, I do not see tv out and sub menu that the person navigated in order to enable tv out.
Hmm.
sorry double post
I was looking for this function too and can confirm it is not listed under the settings. How likely is it that the hardware was changed to remove this feature?
It looks like there are still four contacts inside the 3.5mm jack on the phone. I'm hoping that means the hardware hasn't been changed and only the software so that someone can potentially get the tv out function working on the fascinate

I hope so, was really looking forward to playing NES/SNES via a bluetooth controller (Wii Remote, anyone?) on a TV from my Fascinate!
Itll work just swap the red n yellow cables

i ordered a 3.5mm jack to rca cable, will see if it works when it gets here.
It was tested on a captivate and worked, so we will see, it was cheap so no big deal.
All I have at my disposal right now is a 3.5mm Stereo Plug To Dual RCA Jack Adapter but all it has is red and white. Will testing that lead to anything while I wait for the other cable?
Plug the red where the yellow go n the white in its right place. Make sure you have tv out selected in settings first. It should show on your tv.

Some of you proabably already know this, but for those of you who don't, check this out. If you have a PS3, and it's connected to your home network, you can stream movies off your phone, through the PS, onto your TV, using the AllShare app. It's not the greatest quality, but certainly ups the wow factor of this phone when you demonstrate it for your friends. Also, if your TV is networked as well, you can use your phone as a remote to stream the movies on your computer to your TV, and these play in excellent quality.

Unless samsung removed that feature, it should be in. They claimed the galaxy S line did t.v. out. I know i tested on the vibrant and it worked for all but copy protected movies.

I think for whatever reason, some settings that come with other galaxy s phones, do not come with the fascinate. The obvious one is tv out, then I also read about being able to change the font to a few different preset options, but also cannot locate that feature. There are probably more left out features that I don't know about, due to never playing with any of the other galaxy s variants.

It is definetly not in the software options, however I would not be suprised if Samsung left it out (it is not on the Epic 4g either) until 2.2 so as to help promote the HDMI output option as well. (Why buy RCA for $10 when you can get HDMI for $50 mentality)
Just speculation on my part, I have no idea why the option does not appear. However I would really like to see someone compare the dumps from on of the other US models and compare to see if we can add it in

look in the sounds and display options. it's the last option in that menu on Vibrant.
As said previously the option is not there on the samsung fascinates menu.
I have the cable and it worked on my Captivate, but I dont have a Fascinate in front of me (yet). I would assume with no setting to turn on, you (we, since I have two on order) are out of luck. I know with my Captivates, it worked only when enabled. Mine should be here the 22nd and then I can check.

[Q] Audio via USB?

Is it possible to get audio playing over the USB port from the HD2?
With the iPhones, the audio market have a line out dock which takes the proprietory plug the iPhone uses to charge and sync and outputs to a 3.5mm jack. This bypasses the internal amplification circuitry so that you can use an external amplifier for a better signal to your earphones/headphones/speakers of choice.
I was wondering if it was possible to do this with the HTC HD2.
Can anyone offer any insight?
I'm no expert however from what I know, I think the iPhones dock connector has more than just regular USB connections inside. It may have some audio connections and possibly even a video connection. So I'm guessing the audio actually gets sent through that rather than via USB.
However, I imagine that you could send audio via USB but at a guess I think it might require a processor is some description at the other end to take the audio and send it to the speakers.
This may be totally in the wrong direction but I believe it is probably along these lines
Sent from my Nexus S using XDA App
It's most certainly a question for those of the XDA Community who know the ins and outs of the USB port and what it can actually do.
I'd love to think that it is possible. Whilst I'm happy with the output of the HD2 sound quality-wise, the mere thought that it 'could' be better intrigues me.
Can anyone help explain if it can be done, how it can be done or if it can't be done, why it can't be done?
Just to get a bit more info, where were you thinking the USB audio would be used? Like through a PC and then to it's speakers, or do you have some MicroUSB audio dock thing? I imagine whether it is possible or not depends on where you want the audio to go to.
I imagine if it was through a PC then it would be a matter of software, and therefore be possible. But I don't know about a dock situation.

From the HD2's USB port into a portable amplifier (3.5mm jack) then onto a pair of IEM's.
I guess it is also plausible that it could go from the HD2's USB port to a USB DAC/Amp then out onto a pair of IEM's but that kind of DAC/Amp doesn't come cheaply and then there's a whole driver issue to contend with, possibly.
This is strictly to improve audio in a portable capacity, as iPhone users seem to have been able to do for quite some time.
Alright then, beyond my scope mate sorry we need other developers to check this out I think.
Anyone?

Thanks Johnathon.
Hopefully someone else will reply to this. Plenty of views but no chatter.
Yeah, I'm sure you will find someone though! It is the HD2 section after all more than enough devs in these parts

I do not think it would be, like the DAC isn't it? why not just use the Bluetooth A2DP?

I do not understand your question and do not see how Bluetooth A2DP would help at all.
Final bump
I know that CyanogenMod9 allows audio out over usb on some phones.
I'm really interested to know too so have asked the Q in the android forum: http://forum.xda-developers.com/showthread.php?p=22920882#post22920882
Fingers crossed...
Bumping
There are many more people interested then it shows here.
I know the following must be in place before USB class audio will work:
ALSA drivers in the kernel
USB host
USB OTG
and if all of that is in, then in theory USB audio should work.
Jelly Bean makes this official, which is nice. but many of us still use CM7, especially Tyween Typhoons, for stability, and it would be awesum if it worked in there, although to be honest I am waiting for the final CM7.2 before I test again.

Headphone control support?

Alright so I picked up my N7 yesterday as a more portable alternative to my Transformer Prime. I'm using it primarily for entertainment and social networking where as the Prime will be my productivity tablet. My question is if I'm walking around listening to music with the N7 in my back pocket, will I be able to use a pair of headphones with built in audio controls for the music? If so does anyone recommend a particular pair? Looking for in-ear ones and preferably ones that won't hurt my College student wallet. Personally I'm not a fan of the big Beats headphones primarily because of the fact that most kids that wear them all the time are tools and I don't want to be associated with that stereotype. Haha pun.

Bluetooth headphones are your friend.
A bunch can be found for $30-70. Get at it!
Sent from my Nexus 7 using Tapatalk 2
Unfortunately, the headphone jack doesn't have mic support, which is needed for headset control support. I can't understand why they would leave this out, and mic support was even advertised as a feature on Asus' product page. I'm not sure if they've changed the page since the last time I've looked at it.
Is it something that a firmware update will fix? I know with the TP there were a lot of things that were added with firmware updates. I looked into the Bluetooth headsets on amazon and I think I found one I would use, but I'm still not crazy about the size of them. Even the smaller in ear ones.
Sent from my Nexus 7 using Tapatalk 2
This isn't the kind of feature that a software update can add. The Nexus 7 doesn't have the necessary hardware.
Ah I see. Well I guess I'll just trap a pair of BT headphones off Amazon. Any one have a suggestion on which ones to go for or to avoid?

[Q] Usb "mounting" as a track??

Hello!
Humm, so i thought id ask something about what you can and can't do with usb on nexus 7. To start off with, i've built a simple rig on my car for this tablet, to work as multimedia interface. And it works awesome. The one thing that bugs me, is that the sound quality from the 3,5mm headphone jack going into my car stereo auxiliary input, isn't as good as the USB input on my car stereo.
This leads to the actual question, would it be even close to possible, to have a "virtual" .mp3 file or something like this, "mounted" as the usb? Like, when you plug the usb cord between car audio usb <--> nexus 7, the car audio would think the device has only one track, but that would be like a live stream of the tablets sound interface? I have absolutely no experience in anykind of coding and thus im here to ask you. I might be way out of boundaries on what can be done, you tell me!
Bump!
Am i alone with this matter? Please move this thread if you think it would get better attention somewhere else! :victory:

Hacking sony sbh20 stereo bluetooth headset to use 3.5mm headphone out as 3.5mm in

Just got a Sony sbh20 stereo bluetooth headset (Review) And its great plays my music from my phone wirelessly, makes calls etc. It has 3.5 mm output so it can be hooked up to any speakers with 3.5mm jack.
However being a gutarist and an xda forum member im just not happy with what it can do out of the box.
Is it possible to turn the 3.5mm output into an input so i can use this for wireless guitar playing, perhaps with it paired to my phone which would then be hooked up to my speakers.
Basically i want a bluetooth guitar.
Any ideas or comments on how this may be achieved or if this is even possible.
Another concept that may work would be to use my phone itself as an amp transmitting via bluetooth. Probobly easier to impliment. Any ideas if this exists
No it is not possible, and it's also completely and utterly pointless, since you can buy Bluetooth transmitters for next to nothing more or less anywhere

Far from pointless. It is a mod that involves doing something cool. Just because some companies make a product that can do what the OP is looking to do and for a cheap price does not mean that the OP should not try. If we all just purchased stuff that just works then we would have a world with a bunch of idiots that know nothing. And just wants to be solely ammused via You tube videos of dumb garbage. Oh wait, that is the vast majority of this worlds population. This is an Android forum where people do things the hard way so that they can just know.
I could have purchased a great PC case for not to much money. And v en ry little time spent earning said money. But I decided to mod a MAC G5 case. Pointless? No, far from it. This is truly my computer. Here are some pictures.
And how about my cars factory radio? Sure I could have installed a low level converter. Or installed an aftermarket head unit. No, I found the low levels signal circuits and installed RCA connectors on the back of my factory deck.
Sounds like this is how the OP wants to roll.
So OP roll on. Ill look into the setup you are looking to mod and let you know if it can be done and how easily it can be accomplished.
Edit. Yes, it can be done. You will have to mod the input output circuit at the headphone jacknor somewhere on the board. I will say this. Be extremely patient and use a very very good magnifying glass. Or your phone when soldering. And lots of light. What I did was use an app called overlays and created an overlay that put a flashlight widget whennI opened my camera app. This allowed me to permanently activate the flash LED and use the camera as a microscope when soldering my LG tones to act as an incar bluetooth adapter. Sadly though I broke the setup. But, I just may get what you have there and use that in my car next. Though only of it allows for hi definition audio throughput. Any way. Good luck and take pictures if you go through with it.
And one more thing. Like you stated. You could mod a headset to connect to your guitar and then stream the sound from your phone to the Bluetooth headset that is connected to your amp/head.

Thanks for getting back to me these bluetooth units are going pretty cheap in vodafone stores in ireland right now (25 euro where evreywhere else including sonys website has them for 50) so i might puick up another one to mod, not much experience with soldering anything more complicated than audio cables but it will be a challenge, also propss on the g5 case its definately one of the best designed PC cases with the new mac pros coming out there could be a fresh influx of these second hand soon
