I'm looking for 7.1 HDMI channel output from 5.1 source by repeating Surround Left to Rear Left in software configuration. Perfect solution would be if the process was automatic and allow true 7.1 PCM decoding or jump side and rear channels with 5.1 source.Quite a special setup. My knowledge of the audio engine is limited, so I'm not entirely sure if it will work, but you could give the following setup a try:
- set speakers to 7.1 in Kodi
- enable stereo upmixing
- disable all passthrough settings
If this doesn't work, then your best bet would be ADSP, which unfortunately got removed from core again due to design flaws in the implementation. The replacement ADSP API is still in the works and likely won't be ready for v18 final. But with ADSP you would be able to apply channel upmixing/duplication AFAIK.
