I tried both mac (osx 13.6) and windows 10, through usb 2 and 3. Nothing seems to work. i managed to get it to work once as usb DAC on OSX but it stopped after a few minutes, and since then i could not manage to get it to work again. On windows 10 it never worked, i got the "connected device" sound but the SR15 only charges and the usb mode don't get activated.

Sounds like you have covered the obvious, I'm not really sure what to try next. Reboots, resets and cables is all I can think of at this point. Sorry I was no help.

Did you install the Windows USB driver? Not completely sure if it is required or not:

thanks for trying

i'll try to install the driver on windows and keep trying with other usb cables.

I think you asked about updates - the SR15 uses OTA so configure a wireless connection and it should update itself
Not sure what version yours has but the last released on was 1.63 I believe

I'm on the last firmware. But i finally managed to get it to work. the issue was the cable. I tried maybe 7 différents cable and i finally found one that works every time. funny thing is that it's a crappy cable from an aliexpress chineses game console, so not a very high quality one but it works flawlessly.

So for people who have issue with the usb mode, i would suggest trying all the cables they have to find one that works. Or even better, use the official AK cable that comes with the player (i bought mine second hand and didn't have the cable with it).

I hope this will help

Hidizs MP145 goes very well with SR15. Both single and balanced.

1.64 update seems to have gone OK.

1.64 update seems to have gone OK.

+1 worked for mine also, although not sure what it does

Ok. Tried it. No change. Same thing.

It's been 3 years. Still not working.

I recently picked up one of these SR15 as my first non-iPhone DAP (since iPods back in the day).

What I could use is some advice on how to create a bass-heavy EQ setting which I like for some of my electronic music (Lorn, etc). I have an Ifi Zen DAC I use with my laptop which has a button "XBass" and I am looking to replicate this effect as closely as I can with AK SR15 EQ settings. I messed around a bit myself, but all I ended up with is a very low-volume effect without much bass boost.
I should probably learn all about EQ and study it, etc. but I am living a life with 0 free time right now (like 10 min per 24 hours) so I just don't have the bandwidth to "dig in" on EQ. Any cheater tips would be awesome!

Any tips would be appreciated!

With a single filter like this you should be able to recreate this relatively well:

Filter Type	Frequency	Gain	Q-Factor
Low-Shelf	55 Hz	12.3 dB	0.65

This gets you relatively close.
You can play with the Q-factor, a lower Q-factor (e.g. 0.5 or 0.6) will shift some of the subbass energy into the lower mids, and a higher Q-factor (e.g. 0.7 or 0.8) will do the opposite and shift some of the lower mid energy into the subbass.

If you want a more accurate representation of the exact same curve of the XBass function, you'll need multiple filters:

Filter Type	Frequency	Gain	Q-Factor
Peaking	36 Hz	1.4 dB	2.00
Peaking	47 Hz	-3.6 dB	1.40
Low Shelf	52 Hz	6.5 dB	0.71
Low Shelf	80 Hz	5.8 dB	0.58

This gets you within 0.1 dB of the XBass curve.

Note that you will likely need negative gain to prevent clipping. I would suggest -12 dB... and yes this will reduce the overall volume level. I don't have my SR15 handy to see how possible this setting is in the A&K UI so I can't help there.

I love this level of detail, but unfortunately this doesn’t work with the AKSR15

I don’t see filters and when I go to EQ “Advanced” I can only adjust Freq/Q/Gain

Freq can be 30/60/125/250/500
Q ranges from 2.0 - 4.0
Gain has a wide range


Can anyone provide the cheat code for basshead EQ on SR15?
