Sorry to waste a thread but Iâ€™m helping people.
If anyone wants to know anything about audio and speakers Iâ€™m here waiting to answer your questions.
my speakers on my pc hum from time to time when there no music playing
Wow man I posted that ages ago
A humm can be many problems but usually to with grounding.
If you can tell me what software, sound card and speakers you are running I maybe able to answer it for you.
