    After reading this post I ordered the Audioengine D3 both for better sound quality and some extra power. I received it yesterday but I am sending it back. On my L950 and my Phonak Audo PFE 232 the music through the DAC is less loud then through the standard audio exit. I expected it to be the other way around. When the maximum volume on the head phone connection is a 10 the DAC delivers an 8 at the most.
    I can confirm that the Dragonfly DAC (v1.2) works on my 950XL and sounds good. However, it also has a loudness issue similar the one you describe above. I must turn up the volume all the way (which happens to show on the phone volume slider as 'external screen').

    I am using Sennheiser HD650s which are a little harder to drive but the phone still does drive them louder through the headphone out jack. I am guessing it is a problem with the USD DAC interface implementation in the phone OS. My laptop does not have this issue when driving the same setup through the Dragonfly. It will go very loud.

    Microsoft really need to check and update audio driver, firmware or OS, because there are really a lot of issues with audio playback, speaker and headphone jack.
    But as always it needs to be reported on a Windows Feedback.

    I bought a USB C male > USB A female adaptor and plugged my Cambridge Audio DAC Magic XS into my Lumia 950. OTG functionality did not work. I tried to download the driver to install for the DAC but W10 mobile does not allow the user the rights to install. Does anyone know how I can get around this?

    Strnage - I dont get any volume drop off at all. In fact, very slightly louder to my ears via the DAC. Which app(s) were you using? I wonder if the usb-c to usb-a adapter can make a difference? I wouldn't have thought so, but there are so many potential variables within the 'chain'. There is a discussion on USb cables and impact on audio over on the NAIM forum...some differing views and some interesting points on shielding

    I also have the dacmagic xs and tried with my Lumia 950 xl but no success. I believe its to do with the current draw of the particular DAC. This DAC has a higher requirement apoparently.

    Which DAC are you using? The post below made me think that maybe it is the USB power draw requirements which may be affecting the volume. There was a new Dragonfly product announcment at CES 2016 that mentioned the new version has a much lower draw.

    Thanks.

    Audioengine D3.. as per discussion further up in the thread. Works fine for me, but does drain power. About 7hrs from 100% to off.

    Posting this link, which is a discussion of sensitivity. (I'm sure one can find many other information sources on the subject.)

    What is sensitivity?

    The problems noted above involve amplifier power output and headphone sensitivity, i.e. headphone amp output (usually in mW), headphone and IEM sensitivity in Ohm.

    I searched last night but could not find these most basic and most relevant specs for either the Audioengine D3 nor the Phonak IEMs. Very strange. You must consult these specs to properly match a headamp and headphones/IEMs.

    Although I only have the Lumia 930, with my Surface Pro, I'm using the portable USB DAC from LH Labs, Geek Out 1000, the 1000 being the power rating in mW, i.e. 1000 milliWatts, or 1 Watt. This can power any pair of IEMs and almost all headphones.

    I also have a few different headamps that I use with my L930 (and previously L920, L900, and L1020), and all are significantly lower volume output than with a headamp. My experience is that the Lumia don't crank up when it comes to music volume. But using a headamp is more than just volume. Having additional output power allows the headamp to better "drive" the IEMs/headphones, even at lower volumes.

    The sensitivity rating is such that the higher the number, the easier they are to drive, meaning less power required from the amp. The lower the sensitivity rating, the more power needed.

    Hope this helps.

    Enjoy the Music!

    Cool, looking to DAC, Audioquest DragonFly v1.2 for myself.
    Did anyone try Audioquest Dragonfly with the Lumia models? Must require an usb-c to usb3 adaptor.

    I tried the Dragonfly Black with my Lumia 950. Music is definitely coming through the DAC (detected as an external screen). I got some digital noise when listening to music with Groove, but I also got noise on my old Macbook Pro with 2Gb RAM. Maybe it has something to do with that. With the Lumia 950, you cannot set the sampling rate so it uses the default 96kHz (magenta). First I thought this was the source of the noise, but as mentioned I heard it with the Macbook too, where I set the sampling rate to 44.1kHz.

    Sidenote: I discovered that when an external screen is attached, you first need to turn up the volume and turn it down again in order to get the right volume on your external screen. Otherwise the volume is extremely soft.

    Hi there guys.
    Recently I've bought a Lumia 950 XL and with it I decided to buy the LG G5 Hi-Fi Plus (B&O PLAY) DAC, as it's also standalone and compatible with Windows OS, considering the price was a bargain for both phone and DAC.

    Since it has a Type-C to Micro USB adapter-cable, I bought a Type-C to Type-C cable to use it with my Lumia 950 XL.
    When I plug it in with the earphones in the DAC, I got a notification saying the USB device could not work and to try it on a PC.
    The DAC doesn't work, but the on/off + volume buttons on the earphones pad, they work!

    Could it change anything by using another adapter?
    I ordered a mini adapter micro USB to Type-C to use with the original LG cable.

    I'm also downloading a Fast Ring build now, to see if there's a small chance to make it work.
    I'm wondering if I'm the only one who bought the LG Hi-Fi Plus DAC, using it with a Lumia phone.
    On my OnePlus One it works amazingly.
    Damn... I'm quite upset.
    C'mon Microsoft, do something right!!! Don't let me regret the phone.

    UPDATE:
    After downloading the latest Fast Ring build, at least the DAC is seen as External Screen.
    Unfortunately the audio is completely distorted, as the pitch is wrong. Without earphones the audio pass through the phone speaker and not the DAC.
    At least is a small step forward, but I can't believe the are so far away from Android or iOS, as if they created Windows OS few months ago...
