I’ve clearly just stated that it works with my motherboard AND separately with my sound card when using a default KDE Plasma 5 EndeavourOS install.
I don’t need any more hardware, I don’t even need the soundblaster, I can use my motherboards built-in S/PDIF port and get full 5.1 Digital Surround Sound support, but for reasons unknown to me this support only works in;
• Windows 10
• Windows 11
• EndeavourOS
I have tried numerous other Linux Distributions such as;
• Pop_OS!
• Debian
• Ubuntu
• Fedora
• Fedora Kinoite (KDE Silverblue)
• PeppermintOS
• Deepin Linux
None if these other distributions I’ve just listed other than EndeavourOS support 5.1 Digital Surround Sound with ANY of my hardware regardless of if I use the motherboards built in RTL1220 equipped S/PDIF port, OR, if I used the Sound Blaster AE-5 S/PDIF port, it doesn’t come up as an option in the sound settings for those distributions.
I’m trying to work out;
• Why doesn’t the option appear in other Distributions?
• What is EndeavourOS DOING/CHANGING that the other Distributions are NOT doing in order to get 5.1 Digital Surround Sound working with MY hardware?
Clearly EndeavourOS is doing SOMETHING, otherwise my hardware would be unsupported in EndeavourOS just like it seems to be in all these other Distributions.
