Hello. I just bought youin tv-box with spdif output to connect to my old home cinema which supports DD and DTS. I have tried Netflix and it only outputs 2.0 sound. I had already read that Netflix outputs sound in DD+, but I also know that Android TVs with spdif output have the option to put spdif in the sound menu (like my box s) and thus Android TV itself takes care of doing the conversion from dd+ to dd. The problem is that this box does not have such an option. I have read complaints about this same problem with the mecool km2, and I think that the problem is not with the manufacturers, but with Android 10. Am I right? Is there any way to get 5.1 on Netflix?
This is the audio option menu:
Android 9 was the first version that came with an "SPDIF" option available for devices with the optical port that was able to convert Dolby Digital Plus to Dolby Digital from ANY app, however, if the option is gone in Android 10 and above then it could have been a Google's decision and it's hard to know why, at least the conversion is still available in devices with the B variant of the Amlogic SoC (such as S905X4-B) but it works when the box is connected to a TV or AV receiver with only Dolby Digital decoding by HDMI, I'm not sure if the Youin has it, you'll have to test it out.
