I have been using the Khadas Tone 2 for almost 1 month now and I am totally in love with this device. Thanks for producing such a masterpiece and offering it for an affordable price.
Unfortunately I have a problem with reliably playing .mqa.flac files such that the Tone 2 does the MQA decoding. I use the same system, setup and files. According to the lights under the control knob, sometimes the Tone 2 does the MQA (studio) decoding, sometimes it shows 44.1 khz PCM mode. I have tested this with the same file. Does anybody know what is happening here?
Setup: PC -> USB 2.0 -> Tone 2 (+ separate power supply) -> RCA -> Amplifier -> Speakers
Tested on Windows 10 and Linux Mint 20.1
Windows 10: Foobar2000 (+ASIO plugin), Tone 2 driver, ASIO mode active
Linux: DeaDBeeF and VLC, both use ALSA directly to communicate with the DAC (Tone2 Pro, USB Audio, Direct hardware device without any conversions)

I flashed the Tone 2 using the DFU tool and the firmware from 22. January 2021
