Here is a current log, and the following behavior:
the latest LE8Remix.img in downloads
LibreELEC is able to boot as VM in UnRaid with only GTX 1050Ti video passed through, and onboard "ALSA: HDA Intel, ALC262 Analog" passed through and detected as only available sound output device in Kodi settings. Working as expected. All Kodi functionality is working as intended. Sound, Video, very fast smooth experience.
I did change the video_driver to "gl" as suggested in the retroarch.cfg file. This made it possible to play a game on all systems I have roms for. Except for the Wii and GameCube titles. I can see Dolphin launch when selecting a title from ES, but it crashes almost immediately(a second after the gui appears, it crashes and goes back to Kodi)
Also, there is no sound in gameplay. So I think i need to re-examine the asound.conf file, now that I have eliminated the GFX card audio outputs to simplify those available to the VM(only the Intel audio out)
Also there is no sound output in Spotify. And it continues not to play songs. from any playlists. Occasionally, while skipping through a large public playlist, song after song, it will come across a song that has a video attached to it. those songs, as well as short video advertisements, will in fact play. i can watch the progress bar move as expected for a playback. But no sound. and then skipping to next song makes it return to not playing anything successfully and jumping along to the next song. An error appears along the top of the screen, I will attach a photo to show shortly
Thank you both escalade & 5schatten for both your works, and your help and support. I come from years of android development(please see Bliss) and a few years of Kodi experience. As well as some Windows based emulation. Former owner of Raspberry products. But I appreciate your patience so much because LibreELEC and ES/Retroarch/Dolphin are not my fortay at all.
