surround 5.1 over optical cable

us flag

I've been looking in so many forums and tried so many troubleshooting that I am already lost. I've tried doing the steps in this guide https://help.ubuntu.com/community/DigitalAC-3Pulseaudio and pulse audio got to show me digital output 5.1 but my rear speakers didn't make any sound, so I've tried a few troubleshooting steps in many different websites including this one. And after a few reinstalls of various software and codecs and libraries it doesn't show it anymore. So I am hoping to find a solution with you and hopfully get a response and if I am luky a solution. I will send any information that I can so for now I will let you my setup:

motherboard: asus tuf gaming b450m-plus ii

cpu: ryzen 2600

graphics card: nvidia ge force gtx 1080

OS: Ubuntu 20.04

let me know if i can give you any more information. I am really comfortable with my OS the way it is now and it took me a lot of time to set up all the things the way I like it. I don't wanna make a windows install because of something that may be just a few command lines. thank you

If you are trying to get true 5.1, it is impossible over optical cable. It doesn't support that many channels. The only way you can get 5.1 is through an encoded stream like DTS or DolbyDigital. In this case your media must support this encoding and your audio equipment must be able to decode it.

Have you manage to find a solution to this problem ? In fact I have the same issue, I can see the surrond option in pavucontrol, but no sound through the gnome test. Some sound are playing, but it's like more a noise thant something else. Have a nice day

In a previous version I followed the information in this link https://ubuntuforums.org/showthread.php?t=2381055 and it worked perfectly, but in version 22.04 it doesn't work, the 5.1 option appears in pavucontrol, but when selecting the audio it crashes, and when it does not lock, when clicking on the speakers to test, no sound is emitted. Does anyone have the solution? Realtek ALC889 chip, spidf output.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
