Sound profile 5.1 not visible, but 5.0, 7.l is
Hi, I'm having an issue that the sound profile I want to use is not showing up as an option. I have an older analog surround speaker setup which has the trusty old-school color-coded jacks to connect to the PC. The 7.1 surround works fine with Windows on the dual-boot.
In Fedora (23 currently) the 7.1 doesn't send any audio to the side left/right speakers in 7.1 mode - all other speakers and the subwoofer work fine. OK, fine, I'm good enough with 5.1, but that's not an option. My system shows:
(Analog - Line Out - Built-in Audio)
as options. Why does 5.1 not show up? How can I force that profile to appear?
