I have something weird with my Edifier speakers. Maybe a ferrite bead can resolve my issues.<p>I have my setup as follows:<p><pre><code> Lenovo P1 --[hdmi]--> Samsung monitor ---[3.5mm]----> Edifier speakers
Desktop computer with Creative Soundcard --> [3.5mm] --> Edifier speakers
--[displayport]---> Samsung monitor
</code></pre>
I don't have any noise or scratching when I work on my Lenovo. I don't have any noise or scratching when I work on my desktop <i>without</i> having the connection from Samsung monitor to speakers connected. However, when I have everything connected I get a slight noise and scratching sound which gets more pronounced when I start to load my GPU more, for instance when running a game.<p>At first I thought this was a ground loop, but the noise isn't constant, and isn't directly coming from my computer or sound card but indirectly via the Samsung monitor when I start to game and my computer draws more power.
I've been wondering if one of these would solve folks Ikea chair problems (where the piston causes emf sufficient to make some monitors loose signal)
