I try many solution after a humble search on the net but without success. The output of pactl list sinks is attached.
I found a patch in solus development portal by the developer stalebrim (Jake) https://hastebin.com/qaxodorega.diff But i can't test it as i have no experience with kernel compiling and patching.
