Hi, I wonder if anyone can help with this, I watch hours of fishing video's and catch up tv on my laptop but I keep getting random music / adverts playing over whatever I'm watching, which can often drown out whatever I am watching so I end up pausing it until the sound stops, which is most annoying (as I've put up with this for ages now) 
Can anyone suggest a simple solution to this please ?

many TIA Keith
