pulseaudio does not start

Fixed

Description

Applications that make use of audio (and by default, pulseaudio as their backend) fail in various ways.

mixer fails with:

May 23 15:14:44 porter mixer[10167]: PaClient: connection failed:  Connection refused

radio also fails attempting to connect to Pulseaudio

mediaplayer fails to play streams resulting in log messages from gstreamer's pulseaudio plugin:

Could not initialize supporting library.

It turns out that the pulseaudio daemon never starts:

root@porter:~# systemctl status --user pulseaudio.service ● pulseaudio.service - Sound Service Loaded: loaded (/usr/lib/systemd/user/pulseaudio.service; disabled; vendor preset: enabled) Active: inactive (dead)

Further, the pulseaudio socket activation unit is not enabled:

root@porter:~# systemctl status --user pulseaudio.socket ● pulseaudio.socket - Sound System Loaded: loaded (/usr/lib/systemd/user/pulseaudio.socket; disabled; vendor preset: enabled) Active: inactive (dead) Listen: /run/user/0/pulse/native (Stream)

I've confirmed on my 0512 build that pulseaudio is socket activated by reviewing the output of systemd-analyze and also noting that the server is running so something changed since that build date.

Reproduced the same behavior as https://lf-automotivelinux.atlassian.net/browse/SPEC-611#icft=SPEC-611 with no audio on removable media resident files. Confirmed the gstreamer error messages noted in the description.

Workaround is to run

systemctl start --user pulseaudio.service

and then audio will work again.
