I didn't see anyone mention about this here so I thought I post about it in case someone is wondering or is searching about it in the future.
For anyone that is an audiophile or just wants better audio... I have tried a USB DAC with our Xperia Z1 and it works great! As usual you need a USB OTG cable and plug directly to the DAC (or DAC/AMP combo). The USB port does output enough current to power the DAC and even charge it (a little... I don't think the Z1 outputs the full 500mA). Android volume controls also work and it controls it. All audio goes through the DAC and no additional software is needed. I even tried it on CyanogenMod 11 when I had it installed briefly, works just the same!
In my attached pic, the DAC Amp combo is the iBasso D2+ Hj Boa along with Audio-Technica ATH-M50 Headphones. It shouldn't be limited to this DAC. Once you have DAC support confirmation it should generally work with any driverless USB DAC.
And yes the DAC sounds way better than the built in audio. The built in audio chip is okay... but there's no life/fidelity in the audio. And no amount of equalizer can fix that.
Must be a pain in the ass to carry around and those flaps make it worse.

Carrying around isn't that bad... you can jam everything into a large pocket. This is more for a table setup, like if you are sitting at a desk for work or traveling on a plane. And yes the flaps kinda suck... the downsides of waterproof.
I actually don't use this setup very often. I also have the new NW-F886 Walkman which already has a really DAC built in. I usually have that hooked up to a portable amp. Using the USB DAC/AMP on android is a fun test I like to do whenever I get a new phone. It's just good info for anyone that wants better audio! :laugh:
I already posted my comment about the USB DAC (iBasso D10, Cobra) in this thread, post #37

I was very happy to hear to sound from my DAC, as soon I plugged it to the Z1, as soon I got it, Sept 2013.
iBasso D10 has feature to disable charging from USB. which may extend the Z1's battery life.
I recommend to use a right angled (L) USB OTG cable. and it fits much better or securely than the straight USB OTG cable.
Thank you.

Another USB DAC user :good:
Actually I am using a right angle connector in the pic but my case actually gets in the way of it. I think the one I have is too big... it's a DIY version of the micro usb connector so it maybe bigger than normal ones.

I see. I am using generic OTG USB (F) and generic standard Mini USB cable, and I don't have any problem when using it, with the Z1 in soft casing.
Eventhough the digital audio stream is not 'bit perfect', ie, sound signal is mixed and resampled to 48kHz, but, it is enough to enjoy most of it.
As I mentioned in the other thread, I only listen to lectures and talk shows or podcasts, which most of them are sampled at 22kHz AAC (24kbps bitrate), so it the resampling effect/artifact is not significant.
The good thing to use DAC+headphone amp, we can get better dynamic range and able to drives headphones/earphones/IEMs at optimum level.
Thank you.
So now Z2 is out and it specifically mentioned it support USB DAC but not with Z1.
I have a usb DAC personally (Fiio E07k) and it works with xperia Z1 with usb micro to mini cable without any modification to the software.
Any difference between them Z1 and Z2 in terms of functionality?
I was actually thinking about picking up a USB Dac I am still using my home made CMoy amp with a Burr Brown OPA 2132 P was thinking it might be time to upgrade good know know the USB Dacs work with the Z1
Have been doing this since the Z1 came out. Now it is my reference portable system, sounds better than AK120 at a fraction of it's price.
The near fatal flaw of lack of memory space is getting fixed by 128GB microSD, I am happy.

As product owner for USB Audio in the Z2, I would like to explain about our USB support.
In the 2013 mid- and high-end products (Z, ZL, ZR, Tablet Z, Z Ultra, Z1, Z1 Compact) we support USB Audio from the Android Audio framework, which means that all audio is resampled to 48kHz/16 bits, and mixed in with notifications etc. This means that we have "bit-perfect" reproduction only for tracks with this sample rate originally (and such are not very common) and turn off all system sounds and all sound enhancements (and even then, I cannot guarantee that we are 100% bit-perfect).
In Z2 and T2, however, we have introduced a new mode, "High-res audio over USB", where the audio stream is sent directly to USB after unpacking/decoding (actually, when selected, this applies to all audio data, no only high-res, so internally it is called "Direct" mode).
The only exception is if a DAC does not support a particular sample rate, in which case it is sent to the audio framework in the previous manner - for instance, some DAC's which support 96kHz do not support 88.2kHz, strangely enough.
Anyway, in this feature we support 44.1kHz, 48KHz, 88.2kHz, and 96kHz in either 16 or 24bits using USB Audio Class 1, and also 192kHz and 176.4kHz using USB Audio Class 2 in Asynchronous mode. The file formats can be either WAV or FLAC for lossless compression, or MP3 or AAC (which decompresses to either 44.1 or 48kHz at 16bits). I guess other generic Android audio formats should work too but they are not in scope since I have never seen these at download stores.
One caveat with 192 and 176.4kHz files is that the Android downsampler does not handle more than 96kHz, so if you get such files, they will only play in High-res mode to a capable DAC, not in any other circumstances.
In this mode, since we bypass the mixer, ring signals and notifications etc are not passed to the USB DAC. If you want these in headphones connected to a portable DAC, you will need to turn off HigH-res mode and everything will then work as in the 2013 products.
I will be present in this forum for questions and problem reports when these devices are released. Currently we are testing with a limited number of DAC' and I will post a list of these soon.

Wow. Very insightful. Thanks.
One more thing, will this High Res over USB feature carry forward to the Z1? Or it is a new hardware feature.

I cannot comment on unreleased features, however, this feature is not dependent on the specific hardware in Z2. Generally, backporting new features into older products is always a question of resources.

Well that's a good point. But how LG G2 (which is marketed to play Hi-Res audio) differs from the Z1?
For the "High-Res Audio over USB" mode on Z2, well, it is still unsure whether Sony will be porting this into the Z1 with the KK upgrade. Right now, what's clear is that USB DAC is supported but with limited audio sampling and frequency.
Tested with Fiio e07. Working great.

Hey there, firstly I have to say I am amazed at the fact I found something online relating Z1's with M50s, so thank you for opening this thread. My question might be a bit off tangent, but I'm currently looking at buying some M50s, and Im sure you know as an Xperia user, the headphone glitch is one of the most frustrating parts about the phone despite it being an amazing device. Do your M50s work with your phone, when plugging them in the standard jack?

Headphones glitch? The only I can think of is if you use like iphone headphones it won't work because it uses the other mic/heaphone standard than the xperias do... is that what you are refering to.
In anycase what you are asking is not related. With any android phone, if you plug in any sort of regular (no mic) headphones the phone audio will go through the heaphones and the voice will be picked up by the mic on the phone. In the Z1 case, the bottom where the external speaker is. So it works just fine (I tested just in case). So if you are going to use it with voice calls, the phone cannot be on your pocket.
Btw side note, I am on cyanogenmod mod (it shouldn't make a difference) but unfortunately cyanogenmod no longer supports USB DAC. Kali mentioned that it screwed up the dock charger so he disabled usb dac support

Thanks for the quick reply. I think I get your point, simplifying my question; I just wanna know if when you plug in your M50 standard headset in the normal jack at the top of the phone, audio plays properly. Sorry for the confusion lol. Also when did you get your z1?

thank you for the great explanation! this info is exactly what I was looking for. Does this also mean that I can send any audio out through usb? for example, Google Play Music streaming app, will the audio stream to my car's usb port? or does it only support locally saved files on the phone? Thanks!
Tried the USB audio out to a couple of external DACs and both have pops and clicks. It appears like the Shield up samples everything to the max capability of the DAC up to 192k. This causes random unlocking of the signal to the DAC causing the pops and clicks. It also prevents the transmission of bit perfect audio to the DAC.
Does anybody know of a way to switch off up sampling in the Shield so that it plays the native sampling rate of the source? Is there some way of "conning" the Shield during the USB handshake?

Thanks for posting this. I have similar issues using a NAD D3020 amp as my DAC. If there's constant audio it's fine, but whenever the SHIELD idles for a bit the next sound (e.g. scrolling through menus) is a loud crackle/pop.
This is sorted now with the 3.0 update. It is now possible to select 192k or 44.1k audio output through settings.

Hi all,
I just saw this thread about USB DAC. My problem is slightly different.
Indeed, FW 3.0 just improved USB DAC compatibility within Android. Still, a new problem arises within Kodi.
With 2.1 FW, I could use my Rega DAC (it is passthrough compatible). AC3 and DTS were sent to my AV receiver perfectly (passthrough working under Kodi).
With 3.0, I can no longer use my Rega DAC under Kodi. Passthrough is not functional within Kodi. I have ugly white/pink noise instead.
So now I'm left with no possibility to let my DAC passthrough the audio to my receiver. This is really boring since my receiver has no USB in, and requires my DAC to passthrough via optical cable.
Good news is improved compatibility under Android system : my other high-end DAC now works with 3.0 (impossible under 2.1) although it is not passthrough compatible.
So my question : what's wrong with the 3.0 update related to USB device or audio passthrough within Kodi ?
Anyone with a hint or solution ? Thanks by advance.

First post here, I had a related issue where I had to modify audio_policy.conf in order to get DTS to passthrough to receiver via the TV's optical connection (Shield to TV to Receiver). That problem was related to the TV's EDID not reporting DTS capability, even though it technically works (probably omitted due to licensing fees). Anyway, in \system\etc\audio_policy.conf, there was also a setting for USB passthrough. You may be able to manually enter the formats to passthrough instead of relying on "dynamic", which relies on polling the device what it supports. (requires root access to edit this).
Thanks for advice.
I'll check this and come back after rooting my SATV
settings
Hi,
I've not been able to root my device, since root is difficult to perform with 500gb version added to 4K TV (TWRP not compatible).
Still, seems like USB passthrough is set to "2". Apparently "0" means disabled whereas "1" is activated (correct me if I'm wrong)
So, do I have no choice except from root ? If you have any clue about this, could you please keep me in the know ?
Thanks in advance,
Pops and clicks
I just put in a Turtle Beach Audio Advantage Micro II USB Analog & Digital Audio Adapter. Works just fine like people are saying but when no audio is going on the led on the Micro II goes off. Then when there is anything, even system sounds it kicks on the LED turns on and my speakers pop loud. Has anyone figured a fix or is this just USB audio. And is an HDMI audio puller a better solution for simple stereo 2.1 setup? Or does that pop too?
OK. Think i found a temp fix. When using USB DAC direct to an analog source it kept popping because it was sending live signal to hot amp every time USB DAC would come back from standby. SO how to keep DAC from sleeping when no sound was live, I installed VirtualHere USB Server From the TV Play store. Checked always as this was only USB device i had plugged in. Then went to setting and only checked Start On Boot. Since then after full restart DAC stays on, LED stays lit and sound is always on. No more pops.
