[SOLVED] Pulseaudio loses ability to record pc audio
I have been working with Ubuntu 10.10 for several months now and have been generally pleased with sound and pulseaudio. I have run into a strange problem for which I believe I have found the cause but not the reason. I was able to record all streams then presumably, after installing install or who know - I lost the ability. Selecting the monitor function pavucontrol then recording tab, produced no active stream or sound activity.
I used VMware to install a clean copy of Ubuntu which recorded internal sound flawlessly and discovered the problem. The default PA source was changed from an input source to an output source. See image below for the correct setup. However, any attempt to reset the default source ended up in PA not being able to connect to the server and consequently no PA. I had to go to a backup to get the sound recording working again.
I am interested in learning what happened and how to prevent this from happening again as I experienced this same thing several months ago. When I am experiencing this problem all sound output is fine - you just cannot record any internal pc streams. Any PA experts out there? Thanks for any insight....
