[pulseaudio-discuss] Problem setting up a service that uses audio

[Stéphane Boucher]

Setup:
Ubuntu Mate 16.04.1
Application to run as a systemd service.  It uses PortAudio, which uses alsa… which uses pulse audio due to plugin.

Due to needing timestamps, I explicitly what to use hw:1,0 and bypass pulseaudio.  However, it seems that pulseaudio is still required for initialisation.

Starting the application as a service (requiring sound.target) does not work.  Because no pulseaudio is started prior to login.

I’m at a loss as to how to cleanly do things.

I see the benefits of pulseaudio, but in my present case, I need to bypass it somehow, and have the service application able to have a properly initialised alsa & hw:1,0.

I’ve tried pasuspender, but if pulseaudio is not running, pasuspender isn’t happy.
