Public bug reported:
I cannot manually reproduce this and it seems pretty rare/random, but
I've noticed in 13.04 at random when I boot up pulseaudio isn't working
at all. It just shows a "dummy output". rebooting has fixed it each time
it happened. I also noticed each time I saw this happen there was an
accompanying hang on reboot, it would just sit at the plymouth splash
and I'd have to use the power button. My theory is that sometimes
pulseaudio fails to start correctly causing the dummy output issue, and
when I reboot it also fails to exit causing the hang.
I've seen this on both of my laptops, one running ubuntu 13.04 fully
updated one running xubuntu 13.04 fully updated. Laptop one has:
brandon@ubuntu-U52F:~$ cat /proc/asound/card0/codec* | grep Codec
Codec: Realtek ALC269VB
Codec: Intel IbexPeak HDMI
laptop 2 has:
brandon@ubuntu-lemu4:~$ cat /proc/asound/card0/codec* | grep Codec
Codec: VIA VT1802
Codec: Intel PantherPoint HDMI
