So I've been trying I find a solution for this, but it's been proving difficult. I have seen that on the nook forums, with a quick kernel mod and a tweak that allows USB audio control (i.e turn on switch for USB audio output), the guys over there have working digital USB audio output to an outboard DAC. Could anyone find out how to do this with cm7/cm9? Cm9 preferably. I assume we have basic USB host capability, since keyboards, etc. work, so its something specific to USB audio. This is definitely one of the only issues I need resolved on my TP.

This is very possible with USB host and OTG Y-cable adapters. When my cables and my computer come in the mail I will try tinkering with it. It'd be nice to see Jack audio running on here. Once July rolls around and HP releases most of their driver and kernel sources, development in all areas will skyrocket for our Touchpads.

Does the upstream port require power even if the device I'm using has its own power? My E17 has its own battery, but for some reason it isn't even recognized through the USB OTG cable. I can't even get USB audio to work on the WebOS side, which supposedly has full USB audio support via pulse audio now...

Hmm, I'm not sure. If it has it's own power supply, maybe you can try to mount it with a standard male microUSB to female USB. I'm about to see if I can get my external HDD with it's own power supply to mount to my phone and tablet. Will report back with results.

Has there been anymore dev on this topic, including the current CM mods? This would make an interesting project for a carputer if the USB audio works.

Hi guys,
been a passive viewer in the xda forums for a long time but never posted anything, so be easy on me - It's my first.
I would like to connect my galaxy s i9000 to the pc screen.
I know there's the TV out option, but it involves a 3.5" to RCA cable, and pc screens don't have RCA jacks.
Does anyone know of a way to do this? and if you know what kind of cable is required that will be great.
I'm using the CM9 rom, build 17 from theam hacksung.
Just to clarify, I want to connect to phone to the PC so I can view the phone on the PC screen.
Thanks in advance
Short answer is you can't.
Longer answer is you might.
Your monitor doesn't have RCA connectors but if you have a tuner installed inside your PC, you might be able to connect it to that and then use the software that came with the tuner to display it onto your monitor.
Another method would be to use a RCA to whatever input your display has converter but they are are usually pricey and after a search for RCA to HDMI/VGA/DVI I don't think they really exist.
Even if there was a 3.5mm to HDMI/VGA/DVI cable, it wouldn't work unless the display was designed to take a PAL or NTSC signal through those types of connections.
With cm9, you need to have 3.5mm to RCA cable plugged in then go into System Settings>Advanced>TV Out. The option is greyed out when no 3.5mm to RCA cable is plugged in and the option has to be checked every time you plug the cable in.
Thanks for the reply,
I knew about the tv-out option, but didn't think about using a tuner - that might work!
Another question, do you think that a micro usb - hdmi cable might work?
I saw a while back that samsung offered such a cable that was designed for that purpose exactly.
I've searched a lot of forums but havn't got a clear answer if this actually works, not have I seen a youtube video demonstrating this.
Does anyone know if using a micro usb - hdmi cable wokrs?

Do you know what tuner you have? I'm not sure if yours will have it but there will be a yellow plug like the ones you find on a TV.
I'm %99.9 sure that the I9000 doesn't have HDMI out through USB. It would seem a bit excessive to have two video out ports. Although you did spark an interesting subject, if someone could whip together drivers to work with something like this we could potentially have HDMI through USB but I don't see it happening any time soon.
Here's another way to view your phone through your PC: http://mymobiler.com/
Hey everyone,
Having a bad GPS -signal as soon as I plug in my headphones (which renders GPS tracking basically useless for me), I am looking for alternative ways of using my headphones while doing sports. Searching the Internet, I came across various microUSB to headphone adapters (e.g. serach on amazon for: "LinkS Micro USB to VGA MHL Adapter+Micro 5pin to 11pin adapter + Charging Cable in Black 3 Feet Kit" or "Universal Micro USB Interface to 3.5mm Plug Earphone Adapter (Black)", I have not enough posts to post links/images, yet). Now I am wondering if our phone will support these adapters and if yes, can I control the volume of the output?
Many thanks in advance!
Using an USB audio device requires USB OTG which our device doesn't support.
Hey @Adam77Root but we have working mhl which anyway is using microusb port. And iodaks kernel have working otg too.
Edit: android L seems will have support for USB audio devices IF they have working otg

MHL uses a different method.
If there is working OTG, USB audio support is enabled in the kernel and USB audio HAL is included in the rom, it can work. Older versions too support it.
For the audiophiles among you, I confirm that the Tab S 8.4 is USB audio capable. My HRT microstreamer USB DAC works perfectly.
What about analog usb audio is that supported too?

Andriod is getting really good support with usb OTG
my amazon.com/dp/B000KW2YEI/ref=pe_385040_30332190_TE_dp_1 Behringer UCA202 Audio Interface Works with both the tab s 8.4 and my s5
also my PS3 controller works via usb otg
USB hubs work as well; now I just need a way to charge the tablet while using usb otg
That is what I am looking after to.
If I only could get my eyes on a service manual I will find a way to charge while OTG is enabled.

There are many Y cables on eBay that allow charging and otg use at the same time. I find it's a bit hit and miss, as some don't work while others do
We might find some info on this in the kernel source as well.
The table for USB Id should say the resistor value needed for the combination that gives charging and USB OTG at the same time.
I'll see if I can find out which module in the kernel that does USB ID sensing.
Hey All,
I'm trying to get my N6 >> OTG >> DAC setup working.
Previously, I was using a Note 4 and this worked just fine. Exact same setup.
On the N6, I'm not getting anything; no output. I'm using USB Audio Player Pro and it does not detect the USB audio device that is my DAC. If I use Neutron or Google Music, it just out rights output to the N6 speakers.
I had a split second of success when using a USB hub that was externally powered, but it stops after a second of audio. If I go straight from the N6 to DAC, I get nothing.
Everything is pointing me to the lack of power output from the N6. I suspect the Note 4 provides more amps?
I found a reddit thread that said they disabled USB charging somehow and had success, but they didn't elaborate on how it was done.
Any help and feedback us much appreciated!
Maybe the fact that the Nexus 6 is not host (OTG) - compatible can help you ?
I don't know how you can make it OTG-compatible, but if you have a way to do this, I would like to know it
USB Audio Player pro works just fine playing 192kHz Flac files through my AudioQuest FireFly, not sure why youre having issues....
I've tested with and Audioengine D1 and a JDS Labs ODAC. Both failing. OTG works, because I can connect USB mouse and USB storage just fine.
Samsung's give out much more power than Nexus devices. Samsung can power a mechanical hdd via OTG where as the nexus generally can't.
Is this something specific to Samsung hardware? Surely, there must be a way on the Nexus. It's essentially a battery and a USB port.

It was originally specific to Samsung. The S3 was the first device able to power a USB HDD.. Whether more devices can now or not, I cannot say.
That's not to say every device that needs power won't work, just those that need more power. I'm sure other usb dac devices work.. Whether yours needs more power than those, I dont know.
like I said, its working for me...so it could be the DACs you have require more power than the NX6 puts out, or maybe it just doesnt like the OTG cable you are using. try another that you know works

With that theory, I should be able to power any DAC using a powered USB (dedicated source) as a buffer. This worked momentarily for the Audioengine D1, but then it is cut-off. I've read somewhere that some DACs will try and detect if the power is from a "self-powered" source. Not sure where I'm going with this as I don't expect a work around. Just wanted to mention that note.

Try with a powered otg cable. Like this; http://www.amazon.com/Micro-Cable-Player-Samsung-Galaxy/dp/B00CXAC1ZW
One plug to charger, one plug to phone, device in the last.

Just where did you come up with that absurd idea?
While the factory firmware is not configured to mount a usb disk, the device and kernel are both most definitely otg ready.
I've ordered a view different cables to test. Hopefully they will come soon.
I'm thinking about using an Amazon Fire 7 inch tablet as a car radio dashboard install, but before I commit to buying one, I can't seem to find any conclusive answers on a few things.
Firstly, does the fire output USB audio so I can use a USB dac?
And if so, is it possible to use a Y split cable for USB audio and charging at the same time?
Any info would be greatly appreciated.

I can confidently say this Fire like most other Amazon devices will not support charging while the USB port is being used for any other function. Can't speak to USB audio out (suspect not) as most go with Bluetooth.

It does seem to be a difficult feature to find on Android tablets.
According to Wikipedia, it's a simple implementation of a USB otg cable that should allow charging on any usb otg device.
USB Otg Wiki
The major problem (presuming the cable does work and usb audio is possible) is that the kernel needs to be able to enable USB otg at the same time as charging.

Yep. The stock kernel on most consumer devices don't have robust OTG support as the most commonly used gizmo is a flash drive. I was able to get a OTG GPS receiver to work but it wasn't plug-n-play by any means. Charging didn't work in that context...although I didn't fiddle with it much.
I've been working on a kinda similar project, I just haven't had time. I'm trying to use my fire as an octoprint server, which is a program that monitors and controls 3d printers. The problem is that it requires usb to be connected to the printer, while also staying powered on. What I'm going to try is remove the battery, step down 12v from the printer to 3.7v and just hack it onto where the battery would connect to the pcb. I'm not sure what the different pins on the battery connector are though, so I'll have to test those. Otherwise, it should work.
