General Comments

Report by Yurii

It is recognized as HS Mark of the Unicorn. It is based on the 32-bit ARM processor Cortex-M7 ATSAMS70N20. DAC ES9026PRO. The firmware version has the number 2.4 and this means that it belongs to the second generation.

He installed Netlabs' USB Drivers version 10.251. (AN drivers versions 11.xx and 12.xx already come without UAC 2.0). After connecting to the computer, the MOTU M4 audio interface was detected as "UAC2 Adapter Wave". In "Multimedia Setup" I set the device "UAC2 Adapter Wave (UAC2 Adapter Ampmix)" by default.

Music plays wiht the standard players play WAV. After installing PM123 and its codecs, MP3 and FLAC started playing.

But there is one thing. When listening, noise periodically appears, some kind of interference. As if a car is passing by you with a creak and a crackle, it increases - a peak - dies down. The interference interval is the same. We need to figure out what it is. A computer, USB, a driver or something else.
