Status in alsa-driver package in Ubuntu: New Bug description: I have a Skylake system (ASRock Z170 Gaming-ITX/ac) with (x)Ubuntu 16.04. My speakers are connected via the SPDIF port, but there is a problem. When I inspect the audio profile (in `pavucontrol`), I see that `Analog Stereo Output (unplugged)` is selected. The speakers play regularly, even if this profile is wrong, but the volume doesn't work correctly - anything above mute will cause the speakers to play at maximum volume. If I choose the `Digital Stereo (IEC958)`, the speakers won't receive any signal at all.
