A very strange fault on the Rivetess' mini lappy.
It has a live mic, and periodically goes into feedback oscillation. Any sharp noise is repeated in the speaker about 1/4 of a second later.
Muting stops the process.
Acer with intel Atom. W7 Starter. Despite the reduced OS, it seems to have a vast number of processes running. It won't let me kill any processes with audio mentioned or I might have narrowed it down a bit.
Any ideas about software taking over the system? Skype has been shut down.
In other respects, it seems to work well and is still used for Skyping on a regular basis.
