The onboard sound device generally works perfectly, but the volume
level can only be set to 100% or mute.
Using the keyboard volume control hotkeys in Unity shows the overlay
and a decrease/increase in the volume indicator, but the volume
remains at its maximum. The mute hotkey works fine. Same in e.g.
alsamixer, I can move the Master channel volume to anything between 0
and 100 but the volume remains constantly at maximum unless I mute the
channel.
Individual applications with their own volume controls work fine.
Plugging in a USB headset and adjusting the volume levels for that device
works fine.
