@SMSL-Mandy -- are there any fixes to the low volume level issues found only when using USB?
I have to turn volume up to "40" (100%) just to get reasonable playback level both for headphone and XLR output. Other inputs function as expected with "very loud" already achieved at "20". My setyp has M500 directly feeding XLR inputs on power-amp.
I am seeing this issue on both Linux (Ubuntu 19, Debian 10) and Android TV (Android 9, NVIDIA Shield) as well as Android Mobile (Android 8, LG Quad DAC device, USB Audio Player Pro) I do not use Mac or PC to see if this issue is platform related. FYI, for Tidal, on Linux with Kodi and Tidal2 plugin, I'm able to achieve the MQA "blue" decoding status. With USB Audio Player Pro on Android, I get MQA "magenta" decoding status.
(What's the difference?) -->

I'd love to try out a fix instead of using amazon prime free returns to return my M500, because, I really like how it sounds and the significant value it delivers at a reasonable price, to the point where I could see keeping it if there was some promise of a working fix. Unfortunately, the volume issue is a real showstopper, especially because of the tremendous, speaker-blowing volume difference you get switching between USB and other inputs.
