I am trying to avoid feedback. If I turn the always connected microphone level to zero with pavucontrol there is none. But when I use Skype it increases it and does not reset it to zero. If I tell pavucontrol to default to an open input, no feedback, but no input for Skype. What I need is a resetting method from the command line that I can add to my Skype startup script. I’m having problems with…

Failed to resume/suspend source: Not supported
I only have one sound card configured in YaST. Any suggestions would be much appreciated.
I’m not a PulseAudio guru by any means, but what does the following report?
pactl list sources
It might depend on the sink module concerned.
From ‘man pactl’ I note
suspend-source SOURCE 1|0
Suspend or resume the specified source (which my be specified
either by its symbolic name, or by its numeric index), depending
whether 1 (suspend) or 0 (resume) is passed as last argument.
Suspending a source will pause all capturing. Depending on the
module implementing the source this might have the effect that
the underlying device is closed, making it available for other
applications to use. The exact behaviour depends on the module.

pactl suspend-source 1
turns the input microphone off which solves my problem. I was using pacmd instead. Many thanks for steering me in the right direction.
Good to read that works for you (and helping to suspend the appropriate source).
