USB DAC support? - Nexus 4 Q&A, Help & Troubleshooting

The auxiliary ports on all phones are crap, does the Nexus 4 support exerting music through USB? If not, is there a kernel that has the capability of enabled that function? Thanks.

Probably yes, but you would need a Y cable splitter for the USB power. In the end you'd get a really bulky setup. Not worth it IMHO.

I don't need the power I just want to send info to my car audio.

That is called USB audio out. The Nexus 7 supports OTG of of the box, but even then it cannot support USB audio out.

So the chances of it working on a Nexus 4 is slim.

[Q] Nexus 7 OTG Problem with External HDD

Hello guys
I have Nexus media importer (not rooted) and when i connect usb stick its working fine but when i connect my external hdd WD 320gb its not working. Anyone knows what could be the problem ? maybe lack of power ? waiting for answers :highfive:
You can connect only device with own power source...
It is possible to use a hub with otg, I have connected a kboard and mouse through a basic 4 port hub as a tester. You should be able to use a powered hub to drive your external HD

So which do you think is the problem?

Both the other posters indicated it is likely a power problem. But, not all external HD's will work, powered or not. My WD 750Gb My Passport HD won't mount even powered.
It is indeed a power problem. My usb 2.0 based wd1600 did the same. Since it does not have its own power source, i wired in 5 volts to its usb cable and that got me up and going. There are some usb 3.0 ext hdds that dont need external power to work though. Tassadar got one and said it runs fine with just the power provided by the n7. So you have 3 options. 1. Use an hdd with ext power. 2. Wire in 5 volts to the cable. 3. Purchase an hdd which the n7 can power.

How can I wire 5v power? You mean by hub with power input?

No. I actually spliced a 5 volt power adapter directly into the hdds usb cable (red and black wires). A little solder and a few heatshrinks are priceless.
I was going to upload a pic of the cord, but uploading anything with the xda app is beyond retarded anymore. Startimg to regret paying for the premium. For the greatest android site on the web, it is a shame that their app stinks and riddled with bugs. Kinda ironic.

Digital audio output over USB? Possible?

Like the title says, would there be any chance to get digital audio out of the phone, so that you could connect an external digital to analog audio converter to the usb?
I'm just curious...

Anyone?

It may be possible with blefish CM 10.1 since it will come with OTG functionality activated in his 3.4 kernel.

True. There already seems to be support added in the audio HAL for USB accessory aswell, but it's not tested.
Whoa! Nice...
Hopefully it will work, so that I could use the phone as a HQ audio source.

Would I need an otg cable (=pins4 and 5 shorted) to connect the USB audio device or would it work with a regular cable? I do need an otg cable for keyboard/mouse, right?

While I would like to add full OTG so it would detect whether it should act as host or peripheral automatically, there will still be manual toggle mode for it. You'd need a male->female switch though, as you can't connect it otherwise.
But does the male -> female adapter have to short circuit the 4th and 5th pin (Known as an otg cable) OR does a regular adapter work?
I'm about to purchase one, so I need to know it.
Besides that, thanks a lot for being (the only?) developer putting effort in this issue!:thumbup:

Edit. Oh, does the 4./5. Pin shorting only make the device detect the host/peripheral thing automatically? So it would work with a regular cable, if you'd turn it on manually?

Car radio and usb cord

Does anyone know of an after market car radio that will work with android using an usb cord? Or is there an app that allows me to do it?

I believe it works with some Android's this way BUT will not work with Nexus phones due to MTP.

Is there anyway to get mtp? Or get rid of it?
Sent from my Nexus 4 using xda premium
As far as I am aware, the N4 will NOT mount on any PC (or car stereo) in as a standard drive anymore.
So unless you have a car stereo that supports MTP, it won't work. You cannot resurrect normal file-system mounting. Well, you can by making you phone a SMB share, but I believe that only works over WiFi.

Regular OTG cable (not the Y type)

Did anyone manage to use a usb thumb drive with the regular OTG? I have one laying around in my room and AFAIK I need a custom rom to make the OTG feature to work. Since I am waiting for the official CM 10.2, I still run stock, I just wanna know if I have to buy the Y type...

The Nexus 4 cannot output 5v through the micro USB port.
The Y cable is your only way.
Look for the one with a male and female micro USB also with a female USB.

You should be able to use the cable you have but you would need to run it through a powered USB hub

If you answer to my post i have to thank you but i also have to comment that this hub has AC plug in for power!!!

Look at post #795. If your linked device is like marhensa's, it should work. However, it's hard to determine exactly.
Of course you need to flash ziddey's kernel for any OTG to work.

Trouble using OTG to connect to Cleanflight

Anyone who messes around with drones will know what I'm talking about. On other devices with micro-usb, I was able to use an OTG cable and use Cleanflight Flasher, Ez-GUI etc to mess with my Naze32 flight controller. I can't get any power to the FC using my Nexus, USB-C to micro adapter, to OTG. Anyone have any ideas?
Sent from my Nexus 6P using Tapatalk
I have this problem too.
OTG isn't supported I'm afraid. It's due to USB-type C connector not supporting it.

Well that really sucks. I mean, I still have my Nexus 7 tablet that I can use... But any time you get a new device and LOSE features you had previously, major bummer.
