I am a bit hopeless, as I couldn't connect the M17 in DAC mode or file transfer with the box USB cable to any of my computers (4 tested) or smartphone (Z Fold3)...
I downloaded the drivers for windows as indicated in the manual .. but nothing happens when I plug the USB-C port.
I can use the same Fiio USB-Cable with A&K Kann Alpha (DAC mode or file transfer).
I can connect a SSD or Micro SD reader to this USB-C port and the M17 allows me to use it, but not a PC or Smartphone. I never had such issue with other FIIO DAP (M9 & M11).
I tried some other USB-C cables which works fine with other dap ..but not with M17
I tried a new beta Fiio USC drivers FiiO_v5.22.0_Beta.zip with no success.
I have never seen such issue, I will try to contact support@fiio.com and hoping they can fix something.

Am I the only one not to be able to use the M17 as a DAC with android 11 smartphones or windows 10/11 PC ?

Edit : It's impossible to join support@fiio.com as my mail is rejected ..

Don't worry, we will contact you in short time.

Trying to get some clarification here: I’ve been reading a few posts about how using the M17 off the DC 12v power supply gives an improvement in sound quality. Can anyone here specify if that’s true for all uses, or just for over-ear headphone mode or on high gain? Thanks.

Yes it does improve SQ significantly but you'll notice it in Enhanced over ear mode (max gain, where you get the full output power), better control bass wise, better dynamic range and extension both ways, also bigger stage This is clearly beneficial even for IEMs especially flagship stuff that scales...

It worked with my Note9. Maybe you tried the wrong USB-C port? You should use the port under the SD card slot.

Some other points :

1) UAPP is working in hires mode DSD too,

2) using an External DAC mode is working fine with DSD format 768khz and DSD512 (via some upsampling of Neutron player)

3) Fiio Audio Pure mode can access to my Upnp server (LAN or WAN) and working fine without any drops and cuts (unlike the A&K Kann Alpha which can be mostly unusable)

4) The M17 can't be a DLNA receiver for my smartphone in pure audio mode, but works fine with bubbleupnp, neutron and mconnect (So the smartphone can become a good remote control with hires/dsd music, better than using BT LDAC )

5) The stock 12V/3A charger (when activating DC input of M17) really impacts the sound quite significantly more than what I expected, I am still waiting the ifi 12V/4A charger to analyze more deeply SQ with another charger.

.. it's really pity I have some issue with USB-C connection, as I can't use allow Wavelet to correct my IE900 or HEDDphone One EQ...

There is also the FiiO link mode with which you can remote control the FiiO application on the DAP.

Thanks for the video didn't manage to make it work with the iOS app... didn't detect the player.... I have watched it looks like I am doing it right except it doesn't detect

Thank you .. and yes, you are right ....
I was thinking one USB-C port with data in/out and the port for USB-B charging .. and now I could see that M17 is one port OTG (which I used with SSD/SD Reader) and one port as charging and DAC/File transfer ....
Which is a quite bad news !!!! As I can't use the M17 as DAC for my smartphone or PC and still using a power bank or a small external USB-C charger !!!! because the USB-C Host side can't be used for charging the M17.

You can still charge from the DC input.

How did you get UAPP to play DSD untouched?

Unfortunately I don't have an iOS device. Maybe @FiiO can say something about it.

the bluetooth features in IOS has not open to 3rd party so we can only use wifi control in IOS and FiiO Android DAPs.

I only use USB-C power banks with don't provide 12V/3A output. I tried with an usb-c to 5.5mm adapter, but it is going directly to 19V/0A which doesn't work with M17. I sill can try to use a power bank Zendure X5 USB hub, I will see.
At least, as the USB-C OTG is separated I can use my 4T SSD usb-c power bank, which is already very comfortable.

M17support Power Delivery as well up to PD 3.0 and here are the specs... I tested a PD charger and it works for charging but it doesn't activate Enhanced over ear mode

When I downloaded this morning UAPP I got a message that new version v 6.0.3.2 was installed.
Then, it told me when I launched UAPP that it was going to use the Internal DAC Hires that was detected when I don't use an external USB DAC.
