Same here, also with AIMP. Ibasso has always had software issues. I left years ago and bought Onkyo, in fact 2x, gave it a chance again now with the DX300. Great hardware, but software is still not grown up. I can not even sort by file type (WAV, FLAC...) , a very important feature for me. Swipe on the top to the next song, then try the virtual button do the same and the same song starts again. This should not happen in that league.Just received the DX300 and very much enjoying its sound with the Sennheiser IE900. However, I'm having problems with the hardware buttons becoming intermittently unresponsive after the display has timed out. It appears to be hit and miss, sometimes after a few minutes and sometimes after 10-20 minutes of playing. It happens both with the Mango android app and the Neutron app. Is this a known issue and does anyone have any solutions or workarounds?
But at least I enjoy very good sound.
