- Add "Requires: pulseaudio" to alsa-plugins-pulseaudio (#368891)
- Fix pulse_hw_params() when state is SND_PCM_STATE_PREPARED (#428030)
- run /sbin/ldconfig on post and postun macros
/etc/alsa/pulse-default.conf, because the former is practically always
ignored, since it is not referenced for inclusion by any other
configuration file fragment (#251943) The other fragments installed in
/etc/alsa/pcm/ are useless, too. But since we are in a freeze and they
are not that important, I am not fixing this now.
