No sound since Win 7 install

  ex-wirecutter 15:53 02 Nov 2009

Have just installed Win 7 and no sound which worked perfectly before. I did get an error message saying Win 7 was not installing certain incompatible drivers so I assume it was my sound card .Strangely I do have a speaker icon in the task bar and when I check sound properties it says the sound is working .
My sound card is on the motherboard so have tried another sound card and amplified speakers , still nothing.There doesn't seem to be any Win 7 dedicated sound cards on my local suppliers website so any suggestions please ? I have checked the plugs and temporarily connected an old hard drive with Win XP and the sound is O.K. on that.

Further to the above I forgot to mention I have tried to update drivers but told that the best driver is already installed .

Even further to the above , have just been on a site called Driver Robot , which claims to update all drivers . Am a bit dubious , has anybody tried them ?

Some bad reviews on this application from Cnet.I suggest you steer clear and try elsewhere!!
On initial install of Windows7..I too got the icon on the taskbar.
This does not mean your sound is working though..I had to install my "Realtek Audio " files from the manufacturers website in order to get the sound correctly installed!
Have you tried to locate an updated driver from your soundcard as this seems to be a driver related issue ..What is the type of card you have for audio on your mobo? Might help someone throw a little light on your issue !

Try start and in the search bar type system. Click on system information. Expand components- sound device. Mine shows Realtek AC'97 audio. At bottom of list it shows driver version as
Searching for this gets me to here; click here
Check your sound device to see if you can search for the right driver.

The link goes back to the agreement window but accepting this and the Vista/ Windows 7 driver is there.

In sound is it set to speakers or digital??
If it is speakerstry digital.
I had a 4 year old Novertech desk top with Realtek
onboard sound had to give up on that and bought a sound card no problems after that.

Sorry for space error should have read speaker try.

Many thanks for all your suggestions will try them and see what happens . By the way sound is Realtek AC'97 and I have downloaded their supposedly Windows7 driver but that just put another speaker icon with volume control on my taskbar which didn't help .

Update , Have now downloaded an updated driver from Realtek , but , when I try to install it Windows security stops the installation saying it is unable to verify the driver . When I click "install anyway"
it refuses . Looks like I will have to try the new sound card option . So much for the "Windows 7
PC Simplified" claim.

Sorry to hear you are still having difficulties.
The best driver I found was the Realtek driver Version which is not digitally signed but installed without any problem on my machine.

Is it the UAC which is preventing your install?
I "took ownership" of the file and had no problems at all.The installation placed the extra "brown loudspeaker icon" which a "mouse hover" will show as "Realtek HD audio Manager"...From here you can set up your sound configuration! Hope this helps ?
