No sound in Windows 7

When you are running an operating system in Virtual PC (or Virtual Box) the audio & video is emulated and may not use the same drivers that your computer has installed. For example, I can be using a Sound Blaster card in my computer but the Virtual PC may use a Realtech emulation so you'd need the Realtech driver for the Virtual PC.

Just received and installed Win 7 on a Dell 4550 in a separate partition.
Dual boot: Win 7 and XP. Upgraded the memory to 1 gb. Got a 4 gb
USB thumb drive. Upgraded the video to an NVidia 6200 AGP card.
Got a new 19" Widescreen monitor. Thought that I was ready to upgrade
to Win7. Who knew that the audio would be the point that WIN7 would
have so much trouble? For the Dell 4550 the sound is integrated -
think that it is SoundMax.

Minutes later... Windows update must have found a driver for it, because
I received a message: Intel(r)82801DB/DBM AC97 audio controller device driver
installed successfully. Thank you windows update.

Now to see if the hp psc 2170 works.

sound isnt working..tried installing the driver but wasnt compatible for win 7..the driver was meant only for win 2000.2003.xp.and vista..can anyone help..would be really gratefull
and if i run windows xp the sound works perfectly...

I upgraded from Vista to Win 7, and there was no sound coming out from my speakers. This will fix it. Go to:

• Start
• Control Panel
• Hardware & Sound
• Under "Devises & Printers," click on "Device Manager"
• Scroll down until you see Sound, Video, and Game Controllers
• Click on this
• On the file that is indented, right click on it
• Click on "Update Driver Software"
• Choose the manual option, "Browse my computer for driver software"
• Click on Browse
• Now you need to know where your audio drivers are installed on your computer. Mine were at C:\Drivers\Audio\
• You should have the right driver after Audio. I am working on a Dell XPS M1330, so my driver is R167846. If you are on a different computer, then you can go to Dell's website and locate the proper audio driver for your computer. Download this into your Audio folder. Then go back and do what I've listed above. Your should should be working after this!

i have a compaq presario v5000 notebook (xp) and i installed a clean copy of windows 7. no audio drivers, so no sound. i was searching for 3 days and no drivers would install. i was about to give up until just now...went to the compaq website and it told me that there was no such drivers for the operating system (windows 7) so i told them i had xp and it put me to this:

i downloaded the second one down: conexant high definition audio driver....and job done

You could have downloaded the VISTA drivers and they would be more compatible with Windows 7.

Good to see it all worked out.

I found this advice simple and useful.

Basically tells you how to install virtual sound drivers AFTER running VM Additions.
Although it refers to a Vista host OS and Vista guest OS setup - I'm running Vista as Host OS with Windows 7 as the guest OS and the above method worked for me.

I am running win7 on my Intel 2.4, 1Gig ram, MSI MS-7095 (Socket 478) Motherboard with onboard sound. The sound is: VIA AC'97 Enhanced Audio Controller.
The sound worked perfectly on XP sp3 and when I changed over to win7 it worked fine. But the I started to experience that the sound would "dissapear" from time to time and now I have no sound at all. I tried different drivers, updating DirectX, Change of speakers, other sound card( Turned out to be compatible up to XP). . .
I see that davinci2 poseted that "On the Playback tab were Speakers and below Realtek Digital Output. Speakers was the default device, and I set Realtek Digital Output as default device" and mine is also on Speakers. But there is no other optinion to choose from.
I am realy at my witts end. . .
Any idea's?
