[Q] How do I get audio from aux jack while using hdmi out on HTC evo?

Not sure if there is a decently priced solution to my problem or not but hopefully will soon find out. The problem is that I have an inFocus projector that has hdmi input with no audio outputs on it. Stupid, I know. So I have a rooted Evo and would like to be able to send video to the projector using the micro HDMI cable while still sending the audio to my Yamaha receiver. The thing is that when I plug in the HDMI cable, the audio coming out of the 3.5mm jack shuts off. I think that there are ways to split the audio from the HDMI output but those are most likely expensive. So I guess what I'm trying to ask is if there is any work around method that allows me to keep audio coming out of the aux jack while I have my HDMI cable shooting video to my projector.

[Q] Audio out for car

I would like the easiest in car audio possible while charging. I have a couple of questions related to the audio output of the razr hd:
1. Would a y cable work with this phone? Im thinking something like this: http://www.ebay.com/itm/USB-Charger...ader_Chargers_Sync_Cables&hash=item53f0a73387
1a. If so is the audio out a line-out or would it be the same as the headphone audio?
2. Is the bluetooth audio out a line-out signal or is it compressed like the headphone audio?
3. Any ever try something like this? http://gromaudio.com/store/usb_adapters/vw_seat_skoda_usb_ipod_adapter_direct_digital_interface.html I only have mtp mode on via usb now so I dont know if this would work as a direct connection.

I'd probably recommend the motorola cable such as this: http://www.motorola.com/us/consumer...icle-Docks/m-Custom-Audio-Cable,en_US,pd.html
Keep in mind that any motorola car docks will have the separation build into the dock, so it'll have a microusb port for charging and a headphone jack for connection to a car stereo. That way you can keep the dock connected and not worry about plugging in cables. As for signal type through the usb, I really have no idea. Maybe someone else can answer that.
Edit: According to this post: http://forums.androidcentral.com/bionic-accessories/118004-bionic-car-mount-y-cable.html#post1318683 there's no volume control on the usb line out, which leads me to believe it's a line level output and not amplified like the headphone jack.

Fm Transmitter

I had great success with a FM transmitter powered by a cigarette charge. It also had a an extra mini usb cable to charge the phone. The FM transmitter is connected to the 3.5 mm jack. I streamed music with Spotify and used Google Maps for navigation. I did not try to connect the phone for calls with bluetooth!

Thanks for that. I guess in the end it doesnt really matter as if its not a line-out there isnt anything i can do about it. The only thing i wonder now is if there are any direct usb connections that that will allow me to control the music from my in dash cd player. Thatd be the tits.

[Q] Line In Recording

Is it possible to use the 3.5mm jack on the Nexus 5 as an input source for recording?
Like connecting it to a guitar.
Thanks in advance.

I don't know, but would be curious to know the answer.
Do you have a piece of hardware that you could test it with?
Sent from my Nexus 5 using xda app-developers app

tried but didn't work...
could be a TRS TRRS problem... not sure...
related?

the n5 is out of my hands right now, can someone test this...? thx in advance.

I believe the only way is via USB...but you have to use an app as Android does not build in USB recording as does Windows. I use this app along with a USB interface and a microphone on this phone and my tablet. Works great and the dev is a great guy. He also makes a DAW (there's a free version) for recording and editing.

that's... too bad then. thanks for info but.

btw, any suggestion for usb audio in? or usb mic? thx.

anyone? " _ "

I use a pair of wired ear buds that have a built in microphone for calls. I'm running CM11 not stock but I just tested and "Sound Recorder" is more than happy to receive its input via the headset jack. I would believe it's just a matter of finding the right converter plug for your guitar.

I have used ASR for recording, works fine over the headset jack. It is a mono source of course. It won't work with a standard 3.5mm plug of course, you have to have the signal on the microphone portion - which is ground (silence) for the standard plugs.
I used the adapter that came with Dragon Naturally Speaking. It has two 3.5mm stereo plugs to one 3.5mm stereo+mic plug. If you use a 3.5mm stereo cable into the mic side of this adapter it works fine.
You could probably rig up something from Radio Shack, but I didn't have to because this worked, and I don't need the adapter for my computer so it was just sitting in the cord box...

thanks to everyone who replied, truly.
it seems that there are 2 solutions...
1) usb sound w/dedicated app
2) cable that turns L/R input from TRS tip to M input on TRRS tip
the 3.5mm/trrs/(left/right/ground/mic) socket on the phone should work as tdcrone mentioned above. as long as a 3.5mm stereo+mic adapter available, or a custom cable that turns the original L or R input into M on the output end.
this is by far the simpler solution, **if such cable or adapter is available**, the caveat emptor is that the record will be mono, and there could be mic gain issues...?
otoh, the usb solution works, at the cost of having to get an adapter and apps for android costs.
@Vegasden: i see that both USB audio recorder pro and audio evolution mobile daw seem to work with usb recorder, and the latter one is just marginally more expensive?
edit: sorry, just realise that one also needs to buy usb audio recorder pro if she/he wants to use audio evolution mobile daw to do usb record

Is me again.
Do you think these will work? They claim to support iPhone only...

USB Type C to 3.5mm Headphone Jack Adapter

My issue
Hi everyone, I have a Nexus 6P and want to route my audio through a USB type C converter to 3.5mm headphone Jack. I have purchased one online, but it doesn't seem to be working. I have seen that the Moto Z has this adapter and I assumed one I found online would be compatible with my 6P. The reason I want to do this is because I prefer for the AUX jack to come out the bottom of my phone.
What I have tired
Changed 'Select USB Configuration' to all the different options and tried playing music.
Tried 'audio routing' apps from the app store
What I would like to know
Is this because I need to change a setting in my phone to route music out of the USB C?
Do I need to get some kind of DAC to allow support for this?
Has anyone else tried this with their phone?
Thanks
broj0nes

If you don't mind my asking, why bother?

One reason is that to me it makes more sense to put your phone upside down into you pocket. I've always done this at least. So when listening to music I have to put it the other way round. I have also heard the USB C port offers better sound quality.

Re:sound quality, you'd possibly see a quality increase if you use an external Digital to Analogue Converter or fully usb-c headphones. BUT, if you're using a little dongle (if it's possible), then the phone is still managing the analogue conversion and, thus, a very similar quality of audio output. Now I don't know of the 6p's ability to pipe it straight out iPhone 7 style through a dongle, but short of buying a DAC and going whole-hog on an audio upgrade, I'd just flip your phone the other way in your pocket and go the standard route.
Just my $.02

I have been looking for a solution to this too and I seem to have found one. I poked around on Amazon and I think I finally found adapters that work, here's the link https://goo.gl/QT2ith This the only one with positive reviews so when it comes in on the 30th I'll let all of you know.

Looks quite similar to the one that I got. Hopefully it works for you! Let me know how it goes

I read recently that the current implementation of audio over USB-C isn't very efficient or battery friendly. There's a new spec being ratified to provide audio like the iphone can. Hopefully that's a firmware change and not a hardware one.

I don't think it's possible on the 6P, not without using a USB DAC anyway.
As far as I'm aware, the adapter you have is for a USB 3/3.1 interface. While the 6P has USB-C it is USB 2.

I'm able to get audio out of my USB C port, but it's with a USB headset. Haven't tried it with a 3.5mm headphone adapter, but havd no reason to try it either.

This is weird. Because i have a pair of Sennheiser Urbanites (Wireless edition), and i can use bluetooth, aux, and usb (like for a computer) audio. I once tried to turn off the headsets (bluetooth off, aux and usb still works if connected), and turned off bluetooth on my phone. Then i used my USB type C to USB type A Female adapter (from the google store), and connected the usb-cable from the headsets into the type c adapter. it did output audio through the usb-cable.

Bluetooth headphones usually have their own DAC, so the audio for all but the Aux is still being sent through the DAC first, which is supported by older USB standards.
The new USB 3.1 Audio standard can pass through analogue audio from the internal DAC, which is what I believe phones such as the Moto Z utilise. Otherwise the adapter would require it's own DAC, which would make it far larger and more expensive.

Not sure if you will find a good solution at the moment since they just created a standard for audio over usb c http://www.businesswire.com/news/home/20160927006252/en/USB-IF-Announces-USB-Audio-Device-Class-3.0

Did the amazon converter end up working for you?

My experience so far.
Hi, I ordered some usb c to 3.5mm & out of the box so far they aren't working. I tried Neutron and tried to force the audio to usb but unsuccessfully with phone not recognizing the USB connection.
On the other hand the type C to usb-a adapter worked beautifully using mixplorer. If I get working, will update. Thanks.

Improve headphone jack?

Hi!
I find that the original port jack delivers a sound of poor quality. The power of output is very low.
My question is: Do you think that using the USB type C port with an adaptator could improve the sound quality in my headphones?
Thank you

Buy a external dac or LG product

Did you try the v4a module in magisk with the profile given in this section of xda?

I was wondering if using an extarnal DAC (adaptator usb C to jack) could improve the quality
What is V4a module? is it necessary to be rooted?

Yea, magisk/root is needed for the viper4android module to get the sound tweaks. I dont know what type of headset you got but it its bluetooth then make sure its APT X supported to get the best sound out of the non rooted phone.
These usb c to 3.5 with biuld in DAC are nice but you need to have a premium headset to enjoy from those.... these adapters are like 15 bucks and can do 16 and 24bit output.

yup ofcourse it will and it will be the same as the pixel 2 dongle. Just make sure you buy the correct one with a high res DAC in the cable and not these 2 dollar cheap one's that only convert digital to analog.

You will need a dongle that has a decent amplifier in order to get louder sound than stock without crazy distortion. Decent amplifiers are not cheap. Finding a dongle with a good dac/amp combo is probably the best way to accomplish this

Stick in something into the headphone jack, go to settings, audio and vibration, audio tuner
Play around till it fits your taste.
