    Buzzing/Annoying Sound coming from Left Speaker


    Hello, um yeah I am a Linux Newbie, so please bear with me. I just installed Ubuntu 7.04, after trying SLAX Live CD that a friend let me borrow. The problem is, there is a buzzing sound coming from one of my speakers, it is similar to the sound of a TV on a channel that isn't provided. I have a Intel 915 chipset mainboard, and from what I can tell, the Intel ICH6 is in charge of my sound, so can anyone give me some help?
