Strange sound problem

Hope all is good with everyone?

At moment i am having a problem with streaming sound and playing music files through media player and real player. Sometimes if i system restore to before the problem started then its all good but of course later it still goes wrong. Sometimes i get a large crackle on the speakers and sometimes if i go to a radio station i can get sound from an avert at the start then when it comes to the radio station to play the streaming just stops.
This is also the same with stored music files.
All the drivers look to be working properly:confused:

What sound card do you have?

soundmax intergrated one i think. sometimes when we reinstall realplayer it works for a bit
