[Q] Audio out for car - RAZR HD Q&A, Help & Troubleshooting

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.

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.

Sound while plugged into car charger

Hello!
When I plug my Touch Pro into an active Adapt carholder the sound output of my touch is forced to the charger (no sound output anymore on my mobile).
Is there any way around this? Any registry setting?
Or maybe remove some of the pins from the mini-usb connector on the charger?
Try getting HTC's official dongle which plugs into the USB port and gives you several connectors;
USB for charging
3.5mm headphone socket
2.5mm mini-headphone socket
USB for HTC's original supplied headphones
If you use this, you can plug in headphones at the same time as charging. I use it to route sound through to my car stereo so I can use the phone as an MP3 player and Sat-Nav.
If you don't use the headphone sockets, sound still comes out through the main speaker on the phone.
Hmm I have one of those, but the car charger I use is a slide-in holder, so there won't be much room for the dongle
Microphone unuseable when plugged into stereo
I use the usb dongle adaptor in my car to push sound through the stereo, however this disables the HTC Touch Pro microphone so although I can hear people calling in (through the car speakers) they cannot hear me.
I think it is because the phone thinks the headphones are plugged in and that I'd use the headphone microphone.
Does anyone have a tweak which would allow the phones microphone to remain in action when using the dongle?
Many thanks

I don't have that problem at all, my phone's microphone works fine while using the USB dongle with a 3.5mm jack plugged into it, connected to my car stereo.
Are you using HTC's official dongle, the one with the 3.5mm, 2.5mm USB power and USB headphone sockets?
It works fine for me!

[Q] MicroUSB Headset/Charger?

Has anyone seen a microUSB dock/charger/headset that has audio capability as well as charging the phone? What I'd like is to play music from, have headset controls from, and charge the phone all from the microUSB port on the bottom... or is this what car docks are supposed to do?
The way my car is, it's annoying to plug in the charger on the bottom AND the line out on the top - if there's a headset/adapter type thing, I figure I'll buy one of those and build my own car dock, and potentially speaker dock for the indoors.
OR: Just a microUSB headset - maybe I could add charger wires to it...
Month-long bump: I've realized that all I want right now is a microUSB headset, like for the older phones with no headphone jack. Obviously they don't make these for the G2x; has anyone confirmed another LG headset that works with this phone?
I honestly dont know if anything like that exists but I dont think so because of several reasons. Just a few that come to mind I'm not sure if the kernel driver supports it even if it could; the power running parallel to the audio probably would sound terrible; the USB would probably have to be used with a USB (female) to micro-USB (male) adapter since if you were to find it, it would probably be for PC so needed to be converted further adding to the reduction in sound quality.
Silly question.... why not just use Bluetooth and then usb to charge/data only??
Not a silly question at all. I don't feel like paying for a bluetooth adapter but also, because I've had bad luck with them in the past, as far as sound quality goes; I wasn't very impressed. Are there any good/reasonably priced bluetooth adapters that you've had luck with?
The blackberry audio gateway has been reliable for me and sounds decent.
Hmm maybe... not really a fan of having to plug that in, in addition to my stereo. I'll keep it in mind. Any others?

[Q] Using USB Speakers with Transformer

Hiya,
I got hold of a pair of logitech Z305 USB speakers to try on my Transformer. When I plug them in, the light on them turns green, and the volume buttons on them work to increase and decrease my volume. However, I don't get any sound out of them; sound still comes through the tinny asus speakers!
So, is there any way to change where sound is output too on the tablet? I am aware that I could get a 3.5mm cable and plug that in to the speakers/netbook as well, which should work, but I was wondering if there was a more elegant/less cable-intense solution?
Thanks,
James
It's important to understand that USB speakers (and usb headphones/microphones) are not simply speakers/headphones/mics. They are really little USB sound cards that happen to have a pair of speakers or mic hoooked up to a small power amp built in to them. They do not magically transfer the output of your built-in sound card to the speakers over USB. (like plugging in an 1/8" stereo plug would). So, unless the transformer has support for the standard USB audio protocols used by your USB speakers (and I doubt it does) you won't hear anything out of those speakers. Additionally, since the transformer doesn't know what to do with the USB sound card you have plugged it it doesn't recognize it as an alternative sound output (like A2DP bluetooth audio) and will continue to pump sound out of the built in speakers.
Your best bet is going to be to use standard speakers with an 1/8" jack or a set of expensive bluetooth speakers. Now, will the 3.1 upgrade bring support for usb speakers and headphones? Maybe... I haven't seen anything to indicate one way or the other aside from the very nebulous statement that 3.1 will provide USB host "support".

digital audio out?

G2x doesn't have digital audio out through bottom USB charging port correct?
USB charging port is only for charging?
Trying to get possible sound out to my car stereo.
If I have to use headphone jacks that's fine just alot of ugly wires sticking out everywhere.
no but.....

no only audio out is through head phone jack..but also through DLNA that is good for home tv's computer and such at this time but Dlna is becoming very big and i did read an article a little while back sorry no idea where about them brining dlna to car stereo's but i dont think any are out yet.
Bluetooth Audio
If you have a car radio that supports Bluetooth, you could try to transmit audio from the phone that way.

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

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.
