Ubuntu Multimedia :: Audio Problems Ticking, Clicking Sounds, Freezing And Disappearance

I have the 11.04 installed (see hardware below) and am getting this ticking sound from the moment that Kubuntu boots and you hear the booting sound and until I shut down and it plays the shutdown sound. It doesn't matter whether I watch online audio/video or play my music library. I still hear it. Been trying to find a solution for it for a couple of weeks, but all I've found was other people with same problem but in different releases and with different sound cards. Some describe it as clicking, echo and so forth. The interesting thing is that if I stop the song while it is playing and then restart it again then sometimes the ticking will go away.

The second problem is, if something is playing and something else happens like an alert will pop up from the OS, or I open a menu of the player. Then the song will simply freeze in that spot, like a damaged CD and will repeat the last noise heard indefinitely.

The third problem happens mostly online, but I thought I'd post it here just in case all of these are related. Anyway, if I play a You tube video and then click on another one. Then the second one will not have a sound. I have to reload that page and then the sound comes in.
