Ok so the first thing to check is whether your audio driver is actually working. Do you get any sound at all? This might be due to the wrong configuration of your driver or incompatibility with the os/ service pack that you have. I would suggest that you uninstall and install the audio driver again. Be careful not to download any spyware or malware while doing so.

Also, check whether the Master Volume is not set to mute all. You can make sure that it works by selecting your audio options in the control panel. Now that you have checked this, ensure that the speaker are properly plugged in and that they are on... I know this might seem stupid but it does happen sometimes when the focus is turned to a deeper issue with the computer.

Good luck

Ok, so mine are doing that too. For some reison they will start and stop when a new song changes on my windows media player. I think that mabey the wire that attaches the laptop to the speekers, may be loose or a defect. I'm looking for they help line # that came with my laptop. I would understand why this would be happening with an older compaq, but, I got mine about 2 weeks ago for an early christmas present. Once I contact them, Ill let you know why this is happening after I plug head phones in.

I've had a similar problem, but a bit stranger. About a week ago, i installed a game and everything had been going well. Just a couple days ago though, the sound on my computer speakers won't work. They are plugged in correctly and everything, i even tried them on another pc and they work fine. When i go on Start > Control Panel > Sounds, Speech and Audio Devices > Sounds and Audio Devices Properties ... It says: No Audio Device. After clicking on the Audio Tab, it shows that my default device is: "Modem #0 Line Playback". The other device is: "SB Live! wave device". The SB Live device comes up correctly, but still no sound. And i know that the Modem #0 device is suppose to be the correct device for the speakers. Now, the strange thing about this is, the video game that i had installed has sound. But it is the only game that has it, and nothing else on the computer has sound. Please help, thanks.

I get the same problem but i can hear sound through my microphone headphones but not my computer speakers

There are a few things you can try:

1. check you got the cables in the right places

2. make sure you didnt mute volume

3. check if the speakers are bad

4. Ask operating ppl

5. check on computer for (audio recognition) or something device, see if recognises speakers.
- if doesn't, it's probably either plugged in wrong slot or speakers bad quality
- if does, then the speakers are working, it's just that you maybe muted something.

REMEMBER: Check the most obvious things first, don't check the harder things first. because most places you look for things are in the places where they will be difficult to find. People don't generally look in the most obvious places first.
