For some reason, I had to turn off realtime scheduling for this to work on a Raspberry Pi (set `realtime-scheduling = no` in `/etc/pulse/daemon.conf`).
 
 PulseAudio setup can also be done in paprefs (Debian: `sudo apt-get install paprefs && paprefs`): In the far right tab check the box "Simultaneous Output".
