Hi,
These days when I want to listen to the music or watch something on Windows media player, VLC etc, my laptop's sound keeps shutting off. To get it to work, I have to restart my laptop. And sometimes I have to restart it twice.
Does anyone know how I can fix this?
Thanks.

that a person can check to see if there's a hardware problem by using an Live CD/DVD.

I have a MSI CR61 laptop.
I reformatted the laptop few weeks ago. I installed all the drivers and they all seem to appear as working.
If the sound was not working at all, I could say that the problem is with the driver or the sound card. But it works after a restart. Sometimes I have to restart twice a day to get it to work.
You may have to ask MSI for the exact versions and order to install motherboard then audio drivers. Only they may know this.

to purchase an USB device or try using a Live CD/DVD to determine if it's an hardware issue, other than that, I must defer to the Pro's here as it would be a guess.

Thanks guys for all your help.
I finally uninstalled the sound card driver and when I restarted my computer, the windows automatically reinstalled it. For the moment it seems to be working.
with a little diligence you figured it out for yourself. 
Let's hope it stay's working now.
Best of luck

Hi guys,
I think I spoke a bit too early. This morning when I tried to watch something online on my laptop, the sound stopped working. I had to again restart it.
At the bottom right hand corner of my screen, I have the windows speaker icon which I use to control the volume as well as another similar looking speaker icon called Realtek HD audio Manager. Could this be the problem?
but you didn't give any info on this laptop so those knowledgeable about such can't give you much help 
so the best offer I would have is to purchase an USB sound card.
Here's some for instance =>

I don't think buying one of those USB sound cards is the real solution. Furthermore someone here suggested that it may slow down the system.
I know that there is a bug issue. The sound was working fine before and since 3 weeks this problem has started to appear.
it's a bug with all of the possibilities such as lead free solder bot another member had the problem where his headphones worked all the time but laptop speakers worked off and on. He purchased external speakers to deal with the issues.

I bought a $15 IOgear bluetooth adapter and a $35 Creative Labs bluetooth speaker and solved the problem for me. If I'm away from home, I can use headphones. YMMV. I verified that it was hardware by booting a Ubuntu disc and having the same problem.
But I like the Bluetooth angle. Let's be honest about this industry. No one is producing great diagnostics. We can see lots of crapware such as registry cleaners and more so it's never a sure thing if the OS has or has not been dinged up. Since there is no good diagnostics we learn to try the usual and when it doesn't play out we reload the system to factory condition and if that fails, it's a hardware failure.

How can this be a problem with hardware when the sound test under speaker properties work just fine.
The sound "chip" or more accurately system consists of chips that could fail in odd ways and then you have drivers that are now like a Gordian Knot to unravel.
Read above on one fix found but I continue to test with a bootable CD. Only your entry level or new tech would not have such at their fingertips. The industry continues with poor diagnostics and "reload your OS" to solve issues like this. I haven't seen much change since the 90's in that regard.

I have this same problem, relatively. I have a Toshiba quad core laptop fairly new just over a year old. When i play music or video or any sound period via the speakers, it will after about 1 minute sometimes less just stop silent. Then if i pause whatever is making the sound usually about 30 seconds later it will play sound again and repeat the same issue forever.Headphone jacks and HDMI sound out work perfect. For the record I am a very able computer technician with great skills in electronics, electrical repair. I have tried full system restore (windows 7), No Dice. Tried the driver disable, re-enable, upgrade, downgrade, removal of driver , re-installation from scratch. Even registry level manual cleaning, still no joy. Oh try a live cd! everyone says. This means nothing to most people unless you tell them perhaps an EXACT cd you think will work like say ubuntu live,or hirens boot cd or Joe Blows not real recovery! be more specific for the un-tech savy masses out there. I myself also tried the live cd, bootable usb thumb drive aproach(a windows 7 Barts PE build with tech tools added custom), same issue for me. Microsoft's MicrosoftFixit.AudioPlayback.RNP.Run.exe tool said my laptop was 100% no problem. So after all of this I have deduced that I'm "pooched". A technical term for a hardware failure of some sort. Bad ground on one of the speakers in laptop? an on-board sound chip malfunction? Maybe a solder point, or a trace needs to be corrected? I will have to eventually take it all apart down to the motherboard and have a look. For your average cat, i would not recommend this. If you are past your warranty like me and you do not feel comfortable ripping apart a perfect working laptop otherwise, I recommend external setup of some sort like a wireless usb speaker setup, or a plug in small speaker, a Bluetooth speaker,(real nice if you have Bluetooth on board) or a USB bluetooth mini dongle, then bluetooth speaker would be good. I would recommend CHINA for all, cheap cheap dx.com or Deal Extreme to those not in the know comes to mind. (I buy everything there, slow but free shipping) Just some suggestions, Hope that helps someone.
Sorry to double post, but i found an amazing fairly cheap solution!!! A USB to RADIO WIRELESS TRANSMITTER!! under $20 apparently and then your laptop sound just transmits to your house or car radio!
here is what i found http://www.theregister.co.uk/2010/09/27/review_gadget_keene_usb_fm_transmitter/
definitely have a look if your having the same issue as a few of us. Im going to my favorite cheap china site to see if they have something like this with mini dongle.

The only workaround for them is the Bluetooth audio.
For desktops I toss the 10 or less buck USB Audio stick on it.
Bob
I Have my problem fixed, same issue. Usb to Radio transmitter, or headphone plug to radio mini transmitter i just bought this one for $15 http://www.dx.com/p/tv-computer-cell-phone-mp3-fm-transmitter-silver-320825#.VS2JcpOLA1g great buy.
