PulseAudio Under the Hood (2017)

Is there a GUI tool that lets you really get at the guts of PulseAudio configuration? This has come up fairly recently for me as I was looking to get 7.1 surround virtualization on headphones working on Ubuntu (I did succeed at this).<p>The two tools I found - &#x27;pavucontrol&#x27; seems like just a mixer, &#x27;paprefs&#x27; doesn&#x27;t show you anything about modules. I want something that shows me what PulseAudio modules are available to build a signal chain with, possibly also handling configuring LADSPA plugins in the chain. I was really surprised that there seemed to be no way to &#x27;list all modules available for loading on the system&#x27; (there seems to be only &#x27;list all modules already loaded&#x27; which means I needed to Google to find out what the possible modules are).<p>Is there something like this already? If not, I would actually be tempted to build something like this myself - I need a good excuse to learn Qt :)

A few years back I ditched Pulseaudio for regular Alsa and it&#x27;s been a godsend. No more crackling audio on bluetooth devices, alsamixer which can set all the volume levels and every program just works out of the box.<p>The problem I have with Pulseaudio is that it&#x27;s fixing a problem that doesn&#x27;t exist. It&#x27;s great you can mix and match any channel you want with Pulseaudio but that&#x27;s mostly a theoretical advantage. For desktop users Alsa with dmix offers everything you need, I can play audio, record and mix all at the same time. The few programs which absolutely require Pulse (I&#x27;m looking at you Firefox) can be fixed with apulse, which emulates Pulseaudio through Alsa.
