static sound from Linux box – solved


I thnk the background static has been going on for a while, I’ve been ignoring it like tinatus 😉

Today though, I had had enough, and needed to find a solution.

One quickk search later I found the cause, on some update the mic’s had been activated in Alsamixer, a couple of clicks later, all sorted, clear sound restored 🙂

Ask Ubuntu: Constant noise in speakers and headphones

The most probable cause of constant noise coming in from the speakers is usually mic boost. In order to disable this:

      Open a terminal.
      Type alsamixer and press Enter.
      Reduce the Mic Boost and Internal Mic Boost to zero. Refer to screenshot.
