My computer is playing audio without any program open

Question

This is the weirdest thing ever that has happened to my computer (running Windows 7).

1. I haven't installed anything lastly, except lavasoft adware antivirus
2. When my computer stats then audio starts playing, mostly hip hop
3. There is no programs opened.
4. I tried killing all unknown processed, no success.
5. I tried resetting the firewall options of the antivirus, no success.
6. If I disconnect from internet, then it works.
7. The antivirus is not detecting anything.

Is somebody is streaming from another house? Is that possible? and making my life impossible.

How can I check and stop this?

Answer 1

You could try running the Resource Monitor and see what network connections are open and what program is using it (or netstat with the /b option). If you say it stops when you disconnect the Internet, then you should be able to find what program is streaming it.

Answer 2

Do you have any other Windows computers in your house (or, more specifically, on the same network)? Windows Media Player has a feature called "Play To" that can be used to stream music to another computer, so perhaps that's where the music is coming from?

Answer 3

Is there a music CD in your computer's CD player? This sounds a lot like your computer is just autoplaying the CD, and whoever built your machine hooked up the little cable that lets the audio from the CD player go directly to the sound hardware, allowing it to play through the speakers without needing any software running.

Answer 4

Have you checked the Sound settings? Someone might have changed your 'startup sound' to just some really long audio file that is playing for a long time after startup.

1. Type "Change system sounds" in the start menu and press enter.
2. Scroll down to Windows Logon and see if the sound is what you're hearing.

Answer 5

1. Download and run this, then post the results here http://www.malwarebytes.org/ This will scan for any malware on your system

2. Then launch Hijackthis, and post the results http://www.trendmicro.com/ftp/products/hijackthis/HiJackThis.msi This analyses the registry and various other parts your computer.

Answer 6

It had to be a malware or trojan.

I downloaded 3 different programs to clean malware, one of them spyware search and destroy. I dont remember the name of the other 2, I scan my system with the 3 of them, and each one found different trojans.

I dont know which one fixed the problem but I dont have it anymore.

The other answers related to audio settings makes not even sense, thats why its tagged as a virus and indeed it was.
