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.

hi guys is there a docking system to turn a htc into a hifi like the ipod has?
i absolutely love the 'bose' ipod docker
logitech has a cool one
can you provide some more details about the logitech one?
yes please some more details on the logitech would be good )
Apparently audio isn't available through the bottom (miniUSB) connector, so any kind of dock will have to plug into the headphone socket.
Just thought I'd mention this.
I am using a bluetooth enabled home cinema (Samsung HT-Z310). There are other solutions eg. from Sony. The only problem is that the HD "forgets" the profile settings for A2DP and you have to reactivate it every time (as mentioned in the XDA-Wiki on the HD).
But the big advantage is that you have complete control over your audio player since you can keep your HD with you just like you would do with a remote control.

someone in this thread http://forum.xda-developers.com/showthread.php?p=2971276#post2971276 mentioned that he succeeded to connect headphones to miniUSB by installing driver from diamond/Pro!
i have asked him to share this driver but no reply so again just now i have send him PM asking for the same.
lets wait and see.
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 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.

Do either the HD Station or the Car Dock have an NON-amplified audio line out?
Music sounds pretty crappy playing it through the amplified headphone port or bluetooth audio to my truck. Looking to used one of the docks instead if they have a line out.
The official Motorola car dock has no line out. Only a micro usb charging port in.

Are you talking about the Car Dock? If so, that rules out that option for me.
The HD Station looks like it has a 3.5mm audio port, but i'm not sure if that is a line out or amplified?
The car dock has a 3.5mm female connector at the lighter adapter. I have that running to the front of my truck's deck.
Check the manual here to see if that's what you're looking for.
I have the car dock and have tested the aux out. Its ok but the sound quality is not that good. It like im listing to xm in my car.. sound is ok but not the best. Im am comparing the quality to my Ipod that is hooked up to a digital out to aux cable that sound great. The day someone makes and android player that sounds as good as my ipod is the day i can fully leave apple behind.
this might not directly answer your question but, I have used BT in a few cars and with BT headphones. It sounds fine and I've never had any problems with sound quality. as an AUX input it sounds ok but, playing music off my phone gets pretty old fast. I personally prefer to use USB flash drives. I just put a stereo in with usb and an aux for 90 bucks. i can add on BT for 50 but, i have no use for it really. decks with bt built in cost about 160+. anyway, if u have a usb port, u can use ur phone as an flash drive and play the files directly off of there.
as far as docks go, i just use a cup holder or the dash space that i have.

Wow good catch. Hadn't noticed that. I can't make use of it because I have no aux in, currently using bluetooth, but good to know for future cars.
Thanks!
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!
