I have a similar problem. I found this thread while trying to find out why pulseaudio isn't saving my settings on boot.
When I start Xubuntu my "Built-in Audio" profile defaults to "Analog Stereo Duplex" and I have to manually set it to "Digital Stereo (IEC958) Output". I don't use HDMI or analog, and both of these ports are unplugged. The only sound device plugged into or attached to my computer is the digital out. When I reboot my system or restart pulse-audio, all of my pulseaudio settings are lost and I have to manually change the profile again. I tried editing /etc/pulse/default.pa and selecting my default sink to "alsa_output.pci-0000_00_1b.0.iec958-stereo". When I restart pulseaudio using that configuration, "pactl list short sinks" no longer lists the appropriate sink, and pulseaudio defaults back to "Analog Stereo Duplex" (aka: "alsa_output.pci-0000_00_1b.0.analog-stereo"). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1256511 Title: Sounds settings lost after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/1256511/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
