Hello everyone, I’m having a weird issue with Stereo upmixing from Stereo (when listening to music) to 5.1. Only 3 channels seem to work: front right, front center and rear left (3 channels are silent: LFE/subwoofer, front left and rear right). When listening to audio that has 6 channels (5.1), all channels work correctly (I tested with a few different test-audio files and videos using different codecs and all seems to be working fine).
My setup is as follows:
- VIM3PRO, using Omega 21 NIGHTLIE
- USB DAC Khadas Tone board(2 channel)
- HDMI DAC ESSENCE EVOLVE II-4K(8 channel)
- 5X ACTIVE speaker
Edit: This have been addressed at Kodi forum too:Stereo Upmix working weirdly (no LFE, front left and rear right sound)
I do not know exactly when this issue started but at least a couple of months.
