Feedback from PC speakers during dual source usage
Feedback from PC speakers during dual source usage
I’m experiencing a feedback issue with the new Edifier G2000 PC speakers. Both connections—USB from my PC and 3.5mm audio from my laptop—cause the problem when both are plugged in. Removing either input eliminates the feedback. I suspect it might be related to the laptop being too close to the PC or the fact that the laptop uses a docking station without an audio port, so the 3.5mm cable is plugged directly into it. This issue also appears with a pair of Creative gaming speakers, which is why I chose the new Edifier models.
I've encountered the same problem and recently unplugged the 3.5mm jack on one of my PCs while it wasn't in use. The solution would likely involve an A/B switch configuration if the right connections are available. I'm currently using main 3.5mm inputs from the speakers (Logitech) and a 3.5mm adapter for the speaker connections, keeping both on my desktop to avoid dust and carpet. The outcome is uncertain.
Usually audo feedback happens when a speaker is close to a microphone, and the mic captures the speaker's sound before it reaches the speaker. I recommend connecting both speakers via an audio cable; a splitter might be necessary. What you're experiencing as feedback seems due to audio arriving at one speaker before the other, which makes sense since I'd expect the signal to reach the destination slightly earlier than the Bluetooth transmission.
