Sound output to headphones not working
I am using Xubuntu 12.10 fully updated on an HP 200-5220a. I have a Hi-Fi system plugged into the headphones output. This has worked without any problems for nearly two years until the last 2 or 3 days. Then the sound output stopped. I think I may have reset something somewhere!
I can correct the problem by going into the Menu > Multimedia > PulseAudio Volume Control. Under the Output Devices tab the Port setting shows "Speakers" If I change this to "Headphones" everything works OK as expected.
Problem is that this setting change does not get saved and shows "Speakers" again after I reboot. I then need to reset it each time. I have looked for settings files for PulseAudio but cannot find them. I have tried Settings Manager > Save Session but the setting is still not saved.
