I am wondering how we best get sony to hear and understand this issue.
Currently the Lollipop Walkman app (8.5.A.3.3) is feeding all audio through the android framework (analogous to the Windows Kernel Mixer), which results in unnecessary signal processing and is detrimental to audio quality.
If the Xperia Z Series and the Walkman app are to support Sony's positioning as a brand for audiophiles, they need to set this right.
The USB Audio Player Pro app does most of these things right, which goes to show that it is not impossible to do this. Someone simply needs to sit down an do it.
Am I the only one to see this as an issue?

I couldnt agree more - Sony have this deep capability around audio and the Walkman App is really very good, (as is the Camera) ...
But this capability is only matched by their ability to shoot themselves in the foot by alienating their biggest fans.
I went through this once before with their Vaio laptop range and completely decamped from Sony as a braqnd as a result of crappy support (i.e. stopped buying computers, televisions, and everything else in their portfolio - for about 10 years).
They finally won me back again with the Z2 phone, but are in danger of loosing (this time for good). The ommission of the DAC support was the only reason I bought this device in the first place. And the first opportunity they had, they buggered it up again. #Fail Sony yet again.

With Lollipop, the sampling rate of the digital output via USB is selected to be the highest available one, depending on the spec of the connected DAC.
And the phone always up/down-samples the music file to the selected rate (this conversion cannot be turned off).
So if you connect a DAC that supports 192kHz the phone will output this resolution and if you connect a DAC that only supports lower resolutions the phone will lower the output resolution.

"the sampling rate of the digital output via USB is selected to be the highest available one"
whoever thought this is a good idea, is an idiot.
welcome to the wonderful universe of intermodulation distortion!

Sorry to hear that your DAC is not working. Could you let me know the exact model you have and i'll forward it internally as feedback to see if it's something that we can solve from our end.
This upsampling is standard for Android Lollipop. I'm afraid it's not something that we can change from our end.

I came back to see if there is any update on this one from Sony at all?
Sony, you advertise the Z3 compact as hi-res compatible but you remove a key feature from lollipop that was present in kitkat for hi-res out via usb.
My Chord Hugo no longer works with my Z3 Compact as you have removed the hi-res via external usb support.
The suggestion that lollipop has this support is frankly misguided and wrong.
I am using kitkat at the moment and am very frustrated that I bought the Z3C just as a source for the Hugo and now I have to stick with kitkat.
I hope there is some positive feenack coming our way
Thanks in advance

Sorry to hear that your DAC no longer works.
Z3 Compact still is and the feature has not been removed. But With Lollipop there's native support for it in Android which is now used.
Could you please send me a private message with the IMEI and build number you have in your phone and i will forward it internally to see if it's something we can solve from our end.
