I don't hear any differences between 2.4 and 2.5. Happiness))

My 3 macs have this problems.

Unfortunately, it's the "feature" of dx90. Another drivers or OS can't fix it.

Small wish to iBasso.   Please, add some logic into volume control between headphones output and line-out (like from FiiO X daps). For example. On the street I listen earphones from headphone output with 150 volume. At home/work I connect an amplifier to line-out for big headphones with 255...

They are the same in sound.

Does anybody have about 0.5 sec latency between click "Play" and playing as a DAC? FW 2.4.0 has a strange behaviour with last ~1-2 secs of songs - it cuts it in my case. Do you have the same problem?

Describe your personal experience. Without the list of "too many bugs" you looks like a troll.

All my software players don't work on Macbook pro MC371LL/A. Just updated post before. And I'd done factory reset.

Tried Audirvana+ 2.3.3. No changes: Decibel 1.3.1: JRiver 19:

MacBook Pro model MC371LL/A, OS X El Capitan, Audirvana Plus 2.0.6, iBasso DX90 2.4.0.   1. Connect DX90 as a DAC. 2. Open Audiorvana and setup DX90 as output. 3. Play 16/44 flac...

MacBook Pro mid 2010 + El Capitan = doesn't work. No any sound, DX90 automatically disconnects on each sound: 1. Connect - Audio-Midi has DX90. 2. Click "Play" - Audio-Midi is without DX90. 3. Wait a sec - Audio-Midi has DX90.

Yes:

Yes, I have "DX90" in Audio Midi list. 48 kHz/2 channels/32 bit. Set it default. Checked it on Mac mini 2014 with different songs 16bit/44kHz via VOX. It works, but sound has some clicks every ~2 seconds... Like vinyl:) And I hear this clicks only during playing song. They are absent in...

Paul,   OS X DAC function: on macbook pro 15 mid 2010 + el capitan = doesn't work on mac mini late 2014 + el capitan = doesn't work on mac mini 2009  + el capitan = works!

+ adb in USB Charge Only mode, custom built exFAT/NTFS drivers.

I had written to them and we talked about USB-cables (lol). They asked me to take another one. Unfortunately (for iBasso) all my cables work fine. So, as a result they said "Our SW team will look into this problem". Waiting...

I've checked DX90 with Mac mini 7,1 (late 2014). It doesn't work too. Every 10 seconds music stops and resumes with fade out effect. Firmware 2.3.0 L0, OS X 10.11.2 + VOX. Bad, bad, bad, iBasso! 

  Me too. I have errors in the console:

Line-out has volume control. It's very stange. Controls (home, back) are placed on top corners of the screen. Why? USB drivers provide 0.5 sec latency on Windows and doesn't work on my Macbook Pro. No comments. I hope it will be fixed soon.   Very strange problems for 400$ device.:(

5. 0.5 sec delay in DAC (Windows) mode. 6. Doesn't work with MacBook Pro 15' mid 2010 as USB-DAC with 2.3.0 firmware on Yosemite/El Capitan. 7. UI animation sometimes are slow.
