After updating my firmware to version 005 the audio passthrough function does not work anymore from Kodi 17.3. From Plex (another great streaming app) the passtrough works perfectly for all audio-formats, including the HD-ones. However, the overall performance of Plex on this device is not as good as the Kodi performance, I prefer to use Kodi. Before updating the firmware, passthrough from Kodi did work perfectly also for all audio formats. By the way: I use HDMI audio passthrough and the receiver is a Pioneer SC-LX89 (but the receiver is not the problem here in my opinion). Of cource I use Kodi's Expert setting with passthrough enabled for all audio formats. My receiver can handle all formats. The result is no sound at all or abnormal sounds from the speakers. As a workaround I use stereo upmixing in high quality with a 7.1 speaker setting, leaving passthrough disabled. The receiver displays a 7.1 channel, PCM, input signal. The sound is great, but I would like if the passthrough option becomes fixed. Or do I miss something? Thanks in advance for any suggestions.
