Bug Description

What I expect:
When I use slider volume or when I use volume up button of my laptop, I expect that the volume goes up slightly.

What happens:
From the mute state, one press on volume up do graphically well but in reality the volume is loud and noisy from the first step. And all other up steps do not change the volume.
Doing this with `alsamixer` started show me what you can see in volume-issue.gif attached file.
Indeed when I press volume up PCM volume is maxed to 100 instantly and then Speaker volume and then Master volume.

In my case manually changing the PCM volume in `alsamixer` is the only way to change the actual volume of my laptop. Even changing Master volume has no effect!

Do not know if it is a pulseaudio or a alsa-driver bug (cf. https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/PulseAudioStoleMyVolumes/) but I think it is both:
1/ ALSA driver may not report correct dB information.
2/ PulseAudio may not correctly mix PCM into Master since changing Master volume does nothing at all.

The animation in volume-issue.gif doesn't seem to show any bug that I can see.

My working system has the same behaviour, so I don't think the gif is relevant.

@vanvugt: the gif is relevant in order to understand well the bug I think, I mean it may show the correct way of handling some devices but as I said in my case changing PCM volume is the only way to get volume react normally since Master volume does nothing at all. I guess it can help devs understand where the bug is coming from.

And indeed this is a duplicate of https://bugs.launchpad.net/bugs/1773700. I did not find him before, sorry for this one.
