Is there a way to get audio output from this phone via the mini-USB port? I'm thinking of buying a portable DAC/AMP with USB input to bypass the DAC on the phone. Is this possible?
Don't believe this is possible. The host OS drivers must be supported.

Yes, but it's analog audio so you can't bypass the DAC. However it may be line-level audio that is different (better? worse? Not sure) than the headphone jack.
Somewhere in either General or Accessories there's a HOWTO on making your own "dock" audio cable. This will give you analog output from the MiniUSB port by making the phone think it's in a car dock, which makes it change USB D+ and D- into analog L/R audio.
The link Entropy is referring to is this:

EDIT and also from a quote in that thread:

I'm 95% certain digital audio out is not possible, except maybe for MHL/HDMI audio output via the MHL adapter.
There just aren't any provisions for it.

thanks for the info. I'm reading through that and I don't think that'll work for me. Basically I just want something I can slap into my pocket while at the gym to get better sound out of this phone. I guess a simple line-out is going to have to do and just snag an AMP only.
Would the USB OTG be a viable option for this? Just a thought...
Thanks again for the help!
let me ask you this...is there a clean way to get a "line-out" from the Galaxy S2 perhaps from the USB port (as an analog signal). I have been eye-balling the Ray Samuels Hornet as my portable amp for the Galaxy S2 and I'd like to get the best sound possible out of this phone.

I was at work the other week and had a slight problem.. how the hell do i get music from a TG01 into a sound desk.. I tried to use the micro USB to 3.5mm adapter with a 3.5 to 3.5mm cable into the desk AUX input, we also tried using a 3.5 to RCA cable... the final thing we tried to make sure it wasnt a problem with the desk was to go straight into the DJ mixer using a 3.5mm cable. nothing worked. but Iphones, Ipod, other MP3 players all work using this method...
any ideas folks?
Have you tested the supplied USB to 3.5mm with a normal earbud? do you get sound out of it?
The USB to 3.5mm cable is just a simple Analog Left/Right/Ground port and so it should work with any Stereo plug regardless of the destination
I suspect that the USB to 3.5mm you used is busted
you can also use a bluetooth adapter with 3,5mm plug, the one i use was 32,- euros and works perfect

Not at all.
The TG01 does require a certain resistance to be presented to the device and it is this which it interprets as to how to respond.
If the two data lines D- and D+ are shorted, it will go into Charge mode. If it sees a resistance of around 20 Ohms or more it will switch the audio output to the micro USB port. Typical earphones will have an impedance of around 30 Ohms, while the input to many battery powered external speakers is 4 or perhaps 8 Ohms (ever lower on amplifiers). This is why your TG01 worked fine into the earphones but not your external feed.
This texts it's not mine (just the blue one). It was written for the great kevinpwhite, on MODACO some time ago. And it's true (I've made the resistor modification in a set of stereo amplified speakers than failed as Tomsutton said and now they work perfectly.)
You can read the full explanation here: (I'm xdalover on Modaco )

Cheers pete, Il dig out the specs of the desk and see what the resistance is, I dont remember it going into charging mode though..
Why would an Ipod work but the TG01 wont?

If standard headphones works and aux IN don't work, no doubt. This is the origin of your problem

Easy, an Ipod has a dedicated analogic output. Instead TG01 has a shared USB port with different uses...
Noticed this on mine when I wanted to play music from the phone on my stereo. VERY annoying, and a bit daft of them to do this, even though it's a shared port.
There should be a software option to enable the usb port for purely sound to allow it to pass it across. I see the hardware resistive work as a workaround not the solution (although well done on getting it working!!)
no way. toshiba support:
"There are no settings available on the phone in order to set up the electrical resistance."

With thanks to Pere for the kind words above re. my earlier explanations on this subject on MoDaCo....
....in addition, please note that all of these charactaristics are an intentional part of the micro USB AB 'On The Go' port design and will become increasingly the norm as more devices adopt uUSB.
There is at least one chip being manufactured, but as yet not available to individual purchasers, which will support an external plug in device capable of providing intelligent charging combined with concurrent audio out. Sort of configuration applicable to eg. a car hands free scenario. I imagine that such add-ons will start to become available in due course - this is one of the drawbacks of choosing what is still a leading edge device well over a year after it first appeared !
For the mixing desk input, I'd suggest using an isolating transformer (eg. these here) as the ideal means of coupling - this will provide the necessary impedance (typically >10kOhms) to make the TG01 respond with an audio output while also ensuring electrical separation and maintaining as high quality audio signal as possible.
I've just received the MHL adapter and am excited to be able to use my monitor to display the phone's screen. But my monitor does not have a audio output, so the audio through the HDMI cannot be played. I've rooted and am on the Cognition 1.07 ROM, So is there a hack to route the audio through the 3.5 mm jack when sending the video through the HDMI using the MHL adapter?
Thanks guys,
Did you work out a way to do this? I am thinking of buying an MHL adapter but like you my display does not have sound.
I need to know an answer to this! My monitor doesnt have speakers and theres no way for me to hear the video!
My Dell monitor has 5.1 channel analog 3.5mm sockets at the back for HDMI audio output.
on my SG2 I still can use the audio jack for audio output (headset or just go into any amplifier-audio_in, or any computer etc....) when I use the HDMI cable for TV.
Hey RbbChan what ROM are you using?

Hey how did you get it to work? Which ROM and Kernel?
Same problem for me guys...that's a very unpleasent situation!
It can be solved via software though, I'm pretty sure because there is a lag of about half a second between the audio disappears after I connect the HDMI cable, it can't be hardware only.
Is there a place in this forum when we can ask developers to try and find a fix in their custom ROMs ?
I tried this and it worked (audio through my headphones) but the audio also came out through my TV.
VillianRom 2.42/Ninphetamine Kernel.

Muting the TV ought to do the trick,no?
Thats always a viable option.

Thank you Killer Bee! It works!!!
I know this thread is a couple of months old but I just wanted to say this saved me from buying an unnecessary $100+ HDMI audio breakout. The headphone jack fit the bill since my new monitor doesn't have audio output.
I'm having the same issue as OP (no sound through headphone jack on SGSII while MHL adapter plugged in). From the other posts it seems like using VillianRom 2.42/Ninphetamine Kernel would work?
Would any other roms & kernels work?
Thanks
Is there anyway of using the USB input as audio output for a DAC/Amplifier?
With only looking quickly I found this... http://stackoverflow.com/questions/8650967/audio-over-micro-usb-android-open-accessory
I'm sure it can be done at some point. I'm hoping for some kind of conversion where I can control my car radio similar to how my iPhone did.
It should be possible. The car dock has audio out.

Is it possible to get the Hi-Fi DAC working with a Bluetooth headset?
I think this would do the trick for you http://forum.xda-developers.com/lg-v10/themes-apps/dac-fix-hi-fi-dac-everywhere-t3274457
But really ??? on Bluetooth??? I think you would just be using up more batter for no better sound due to what Bluetooth does.
It's impossible to have the DAC affect bluetooth sound. The data is sent to the bluetooth device.... You would need to plug in a aux cable and plug it in to a bluetooth adapter and well just don't do because you'll need to carry a powersource for that and the adapter and just no lol. DAC - digital to analog converter, so yeah it's still digital when sent through the phones bluetooth.
For the best bluetooth audio get devices that support aptx and if you can find devices that are either bluetooth 4.1 or 4.0.

Even if you plug an Bluetooth adapter in the aux output you will not use the v10 dac for your headphones. It would be: phone DAC - Bluetooth ADC - Headphone DAC.
So probably it sound worse after the extra converting and it defenetly different as if you plug it directly in the phone (dac color the sound)

Ya, your definitely right. Converting to digital and analog back and forth 3 times is like taking a photo and putting it on a copy machine and then making a copy of the copy and another copy of the copy. It's not going to look good at all.
Yes the sound would get worse. I wasn't thinking when I posted this I am a audio engineer so I know a little something about audio lol! Having a long week and I wasn't thinking when I posted this just moved into a new house. I'm used to using viper4android on my Nexus 6 so when I couldn't do that on this phone I got frustrated. But anyhow I'll have to wait for root thanks anyways members of xda! Appreciate the responses!
Hi,
I am looking for a charging stand with audio connector.
Has anyone seen something like this?
Cheers,
codiak
You mean a stand that has a USB-C and a headphone plug for added stability? Or a USB-C stand that has an inbuilt DAC and a headphone jack?

I mean a stand that has USB C and working audio jack. I want to use it as a night stand and listen to music via attached speakers.
For now, I am using a universal stand but its quite fiddly to connect usb and audiocable every time. The Oneplus One had the audio port on top, that was easier.
