Indeed it looks like it does.

Let's try two things:

First, check if upgrading to pulseaudio 5.99 from experimental fixes
anything. There may (I'm not sure) be a fix for volume paths that may
be relevant for you.

If that doesn't work, let's try playing with the hardware volume
controls: run the command `alsamixer` (from the alsa-utils package),
press F6 to select the device (by default alsamixer would show only
the pulseaudio control), and then try moving the available sliders to
see if there is one that is muted or needs to have its volume raised.
