Might want to clarify what the acronym stands for. I have no idea what a DAC is.
That's why I don't like to post technical things in the general section. Yet I know I'll get blasted if I post in developement. DAC stands for Digital-Analogue-Converter.

+1 for posting in the correct section though. Developers DO read the general and q&a sections of forums. Just not as often as ppl want them to - so they post in Development to get an answer faster... which is not the right way to go about things.
to put it in layman's term, what audio chip does the Atrix have
I'm curious this too, hoping for an answer

I don't know but it's clearly sub-par, as audited by audio-gd compass and D2000 ... And you can't change it so it kind of irrelevant.
Mayby also someone know is it possible to have direct digital stream from Atrix (bypassing DAC)?

With HDMI out, obviously, but I was also hoping for digital out over usb, like in the car's usb port. I doubt these car controllers know what to do with that connection, unless you can put it into mass storage mode and treat it like a flash drive.

Doesn't audio output over Bluetooth bypass the DAC?

I even didin't think about this... can someone confirm/deny? I'm not much into BT standard.
BUT I'd like have digital audio stream on cable connection - preferably USB pins - to connect this to external DAC (sth like OSNPA said)

So I traced this out, seems like it has been dead in the water since nVidia bought portalplayer in 2007. Kicking around on the rockbox wiki, I found this android port:
http://www.rockbox.org/wiki/AndroidPort
I read through forums, searched, and looks like an apk for qHD needs to be developed yet. Would like to be wrong. Anyone have info on this?
I hate to dig up an old thread, but this is kinda what I was hoping for. I'm in the process of building a "portable" device that would have a Digital port interface, feeding professional DAC and HiFi headphone amplifier. Never actually tried to connect a phone to a receiver with HDMI connector, but it should work, bypassing phone's DAC and feeding digital PCM signal to external device.
As far as BlueTooth connection goes (for the last poster), then if you are looking for good quality, looks somewhere else. Bluetooth compresses the sound on the fly before sending it to the paired device. For some it might be unnoticable, but to me it is unbearable.
According to http://www.head-fi.org/t/549644/motorola-atrix-sound-quality, it is a Wolfson 8903 L. From what I have read, everything points to the Atrix and the Tegra 2 using a Wolfson DAC. Don't forget that the amp and preamp are just as important to sound quality. Supposedly, ICS may support USB DACs.

Wrong,
Just contacted ('PCWAR'), he said he is unsure, he saw such info on xda forums.
WM8903L is made for Harmony Tegra 2, or tablet Tegra 2.
All Tegra 2 Ventanna uses WM8994 DAC
Yay, we've got the highest end DAC, par with the S3 and Note 2 except bit higher stereo crosstalk.

I can't believe my eyes but the specs page on Samsung's website says it has USB OTG!!!!!!!!!!! I can finally use my portable DAC with this beast!
Check under Connectivity
galaxys2.samsungmobile.com/html/specification.html
That's great news for us audiophiles; I actually just sold my UM3Xs to help find for new stiff (the galaxy2 mainly) . I don't really listen to music that much anymore though.
my Fiio E7 USB DAC is also happy for it!
I just need to find short USB mini to micro cable.
Sorry if this might be a n00b question, but I don't seem to be clear on the subject. Will this allow for me to attach a usb harddrive or usb-stick as add-on storage via a usb-micro-usb connector?
Thanks

Yes, it should work providing the microUSB port can provide enough power to drive your HDD (or if it comes with an adaptor).
I remember having USB OTG on one of my Cowon players and it made life so much simpler when I wanted to copy somebody's music over to my player, or pictures from a camera. Only question is, what kind of devices will Samsung give us support for (I guess once they give out the kernel sources this should become less of an issue).

Yea, there's this 2.2 Android phone coming out that is a couple of tenths of a mm thimbleful; however, there are things called set points which are the minimum points where we can discern differences. I think 8 mm give or take a tenth reaches that.

Possibly, but the phone should already support BT keyboard and mouse anyways, which is much more convenient.

Hi, as the audio recording with the built in mic is very poor, i wonder if there is some kind of USB dock with audio "line-in" capability!?
I think i have seen that for the "bitten fruit" pad...
Does anyone know how to get a good audio recording quality?
My target is to record my guitar (electric and acoustic) while practising with great guitar apps on the tablet.
This would completely round off the guitar practising experience.

Amp simulation is not really my thing so I don't have much experience there. The audio stuff I've done with my Prime has been straight recording and a little editing.
For multitrack recording check out Audio Evolution

Tascam works wonders if you use it with headphones directly connected to it and no modeling.
We, Android users, are screwed when using real time or low latency modeling/amp simulation cause Android audio drivers are quite bad right now.
The latency of what gets in the phone and what you hear is an abomination hehe, it makes impossible to use an app to simulate a pedal or add add an affect for example. The issue relies in the Audio driver used by Android.
As far as i know l, it has been in the Android bug tracker for like 3 years now and it hasn't been fixed. You can search for Android issue 3434.
That's why for example AmpliTube has not released any app for Android

How is sound quality? That will help me a lot in making my decision to jump for one. And do you think that something like this will have a long life span hardware wise?
Also, the big issue for me is the lack of NAS playback or a file explore... we know the guts can handle 1080p playback, but making it happen is a different question

Can you control the audio outputs? I would like to have a set of speakers hooked up to the Q using the banana plugs and then hook an hdmi cable from the Q to the TV. I want to be able to control whether the sound comes out of the amp or through the HDMI.
Hello all,
I'm trying to use a Lapdock as an HDMI screen (there are a few threads about this, for example ), and the video part works fantastically. However, I can't seem to get an audio to play from the HDMI input on the Lapdock. I've tried a number of HDMI sources that supply audio with the video, and while the audio works on other HDMI monitors, the Lapdock doesn't produce any sound.
Does anyone know if I need to do something special to the Lapdock or the connector in order to get audio over HDMI?
Thanks,
Allan
I could be wrong, but I don't think the lapdock uses audio over HDMI. I think it uses audio over the microUSB. I base this on how the other two docks I have work (both the car dock and MM dock).
Wrong, the lapdock does use hdmi audio. same with the dock.

Doesn't the car dock use audio over usb?
Everything I could find thus far suggests that the audio is over HDMI (for example, setting up the audio from a Raspberry Pi to go over HDMI as described - raspberry org/phpBB3/viewtopic.php?f=63&t=6747&p=86484 - about halfway down the page - "Mon May 28, 2012 4:33 pm". For for not providing a direct link - not enough karma on the forum to allow that yet!).
So it seems like it should be as simple as plugging in the HDMI, but that's no working for me. I might try plugging in a USB device as well and seeing that triggers something that will bring the HDMI audio up, but if anyone has any suggestions, I'm all ears!
Allan
The car dock is over USB but its not done digitally. Its just a break out cable. I've had my Xbox/ps3 working with the lapdock.

It works ok on my lapdock with both stock and custom ROM's (I was surprised to find the lapdock has two small speakers built in).
Unfortunately I can't think of any way you could test the speakers on the lapdock to see if they are working.
So if the Lapdock uses HDMI for audio, then what kind of circuit is in there decoding the audio for those speakers? Not the typically higher cost decoders found in TVs or electronics shops, there's not eeven nough room inside the lapdock for those.
So what is working that magic? Anyone?

Its been discussed thoughrouly on the kernel dev threads and is stated in the what works/what doesn't work list. hdmi is not something required to make the phone stable, therefore its disabled and on the back burner for now. plus there are driver issues.

lapdock does use the hdmi for audio. I have rpi 2 b. and two micro sd cards, one with kodi, and the other with debian/Jessie. im a noob at this, so I don't know all the different files in them. but when I use the one with kodi, I have sound through the lapdock. when I use the one with debian/Jessie no sound. however if I connect the pi (with debian/Jessie) to my vizio smart tv through hdmi I do have sound. I don't know if this helps.... and if some one could explain this that would help both of us.
The lack of information on apt-X is ridiculous but I finally found something. According to the apt-X website, no current Sony devices support this protocol. This means that for any of you audiophiles like me, achieving the best sound quality on Sony devices is presently limited to wired headphones. This doesn't apply to headsets such as the Sony wireless headset pro, as pointed out by mrsatan. Just thought I'd share.

My sony bluetooth headphones use wolfson audio decoder which is arguably the best decoder around. I really dont understand what the big deal is with apt-X. Obviously there is some with hardware chips but it looks like their main draw is with software, which can be good or bad, Sony sound optimization is really good on Xperia S. They basically look like another vendor like Wolfson but I have never heard of them. Wolfson is awesome as **** when it comes to audio quality and my headphones are really good.

From what I understand the Wolfson DAC is hardware based in the phone, not in the Bluetooth transmitters/receivers. Bluetooth uses an entirely different protocol/codec to stream audio.. Once you stream via Bluetooth there is distortion. Not everyone notices it, but I do, and that could pertain to the type of music I listen to. That's why apt-X support is a better choice for some since distortion is eliminated. To each their own.

The wireless headset pro use Wolfson DAC since it is a standalone mp3 player as well. It definitely uses it even when streaming from the phone because their is a quality difference. There is no distortion on it because it doesnt decode before it streams it to bluetooth. I am a member of Head-fi.com and I remember before I bought the device we figured out what dac it was using and that influenced many to buy it. We were pleasantly suprised to see it using such a high quality dac.
