If I remember correctly, we’ve already talked about this in another thread.
Then you wrote that there was a version that worked with wifi, just the power on did not work.
You should copy dtb.img from that version to the SD card and try it out.

I added a couple of fixes, the new version has been uploaded to GitHub, it is available on the releases page. (9.2.6-20210209)
I tried a few previous M8 audio configurations, but none of them changed the situation, only Analog and S/PDIF options are displayed in the ALSA list.
I tried passthrough on M8S+ with basic settings, and my TV recognized Dolby AC3 correctly, but I couldn't try DTS because unfortunately it is not supported on the LG OLED TV.
Another question: What kind of S805 device do you have? Maybe an MXQ-HD18Q (a.k.a. "all black" with 1GB of RAM) or an MXQ-m201d (512MB)?
