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.
