After pulseaudio upgrading to 1.1-3 and a reboot meanwhile, the issue
seems to be gone.

So, this finally looks like a plain configuration issue triggered by
unclean dependencies. Hence I'll leave this bug open - if you don't like
to tighten the dependencies, feel free to just close it.

Btw... with libasound2 1.0.25-2 and pulseaudio 1.1-3 alsactl, alsamixer
etc. start complaining:
	ALSA lib conf.c:1220:(parse_def) show is not a compound
	ALSA lib conf.c:1686:(snd_config_load1) _toplevel_:24:26:Unexpected char
	ALSA lib conf.c:3406:(config_file_open) /usr/share/alsa/pulse-alsa.conf may be old or corrupted: consider to remove or fix it
However, this is probably more a pulseaudio issue than a libasound one,
even if the contents of the alsa-configs shipped with pulseaudio didn't
really change...
