16.04 - How to fix wrong audio profile (on Skylake/Realtek ALC1150)? - Ask Ubuntu


i have skylake system (asrock z170 gaming-itx/ac) (x)ubuntu 16.04.

my speakers connected via spdif port, there problem.

when inspect audio profile (in pavucontrol), see analog stereo output (unplugged) selected. speakers play regularly, if profile wrong, volume doesn't work correctly - above mute cause speakers play @ maximum volume.

if choose digital stereo (iec958), speakers won't receive signal @ all.

how can fix this?

the linux kernel 4.10 solves problem.
