I recently obtained a Dell XPS Gen 5 from a friend due to the fact that he was moving. Sound specs: Creative Soundblaster Audigy 2ZS Dell 5.1 Surround A dump from CPU-Z: CPU-Z 1.50 HTML report file I noticed the sound wasn't working at first, so I tried to fix it. Checked all the settings throughout the computer for the sound preferences - No luck I re-installed the drivers - No luck Swapped out the sound card for another Audigy 2ZS - No luck Once again, re-installed drivers - No luck Rolled back to older drivers - No luck Troubleshooting wizard - No luck Check the BIOS - All settings are correct I reformat, FINALLY get some sound coming out. All is good, I start watching some videos on YouTube... Halfway through a song, an extremely loud beep emits from the speakers. When I say a loud beep, I mean a constant high pitched, ear piercing, noise. It doesn't go away until I turn speakers off. I plug headphones in, it emits through the headphones. Sometimes it goes away when I close the browser, other times it goes away only when I restart the computer. Then the sound will work for a minute after I restart, and the same problem will occur. I have googled extensively, no solutions have helped. I really don't know what this could be, I have done everything I've read to try and solve this problem, but it keeps happening. On both sound cards. Please help? Edit: Restarting the computer fixes the problem for roughly 5 minutes, then it starts again.
