Windows 7: My sound is working, but there is no sound

My sound is working, but there is no sound

I had my computer fixed about a month ago, and it is working great, the only thing is that the sound isn't working. This is what I cancelled out so far:

I tried plugging in different speakers or headphones

My drivers are up-to-date

Nothing is muted when I check my Playback Devices

When I click on the sound while something is being played, like a video or song, it indicates that there is volume activity going on, but nothing comes out.

Here is what I have as far as sound: Digital Audio (S/PDIF) that is what is checked and that's the only one available. But when I go to Control Panel/System/Device Manager this is what I have listed.

Sound, video and game controllers-
- High Definition Audio Device
- NVIDIA High Definition Audio ( x 4 ) there are four of those listed.

When I right click sound, video and game controllers and select scan for hardware changes my computer starts to say installing driver updates, and then it fails, this is what comes up and I have no idea if it relates to my problem.

There is a yellow button "!" next to Coprocessor under Other Devices, and it says "Device driver software was not successfully installed" No driver found for coprocessor.

Then under Coprocessor Properties it says "The drivers for this device are not installed. (Code 28)"

A little background on my computer- it was broken with a nasty blue screen and my friend fixed it for me, I had to have the motherboard replaced. He threw in some other stuff too but may have messed with the sound I'm not sure. Here is my system:

Rating: 3.9 Windows Experience Index
Processor: Intel(R) Pentium(R) Dual CPU E2220 @ 2.40 GHz
RAM: 4.00 GB
System Type: 64-bit Operating System

Sorry if all the information isn't there, I'm not that much of a computer guy but I've been at this for a while trying to fix it. Any help would be greatly appreciated thank you in advanced!

Dragulan, welcome to the Seven Forums.

Actually you don't have the drivers for the onboard sound installed. A couple of things you said give it away,

The first is the onboard sound and is using the default Windows driver, and needs the corerect driver The Nvidia audio (all 4 of them, and still no idea how or why that happens) is likely from a Nvidia video card that has its own built in audio for passing audio over HDMI.

That the digital audio/spdif is the only option in the Windows playback properties is the second give away. Once the proper driver is install for the onboard it will show up with the proper name and connection options.

Can't tell you what driver you need as you didn't list the make and model of your motherboard, probably Realtek but there are a couple of others.

As for the coprocessor driver, that sounds like you have a Nvidia chipset based motherboard, which if that is what it is you need to install the Nvidia chipset drivers to fix it. If you could post up the make and model of your motherboard we can point you in the right direction for both the chipset and audio drivers.

Okay the guy who fixed my motherboard is on an internship I haven't talked with him in a while, but I downloaded CPU-Z and under the Motherboard tab here's what it says...

Manufacturer - Unknow
Model - MCP73
Chipset - NVIDIA - GeForce 7050 (rev. A2)
Southbridge - NVIDIA - nForce 610i
LPICO - Winbond - W8327DHG

Bios -

Brand - Phoenix Technologies, LTD
Versio 6.00 PG

Graphic Interface

Version - PCI-Express

If the "Unknow" = Uknown, and the above information I gave you isn't enough, what is a way I can find out the motherboard?

You can find the latest chipset driver for it here,

NVIDIA DRIVERS 15.56 WHQL

make sure to do a custom install and do not install the following bolded parts (not needed and a couple of them have been known to be problematic),

Quote:
  • Ethernet Driver (v73.30) WHQL
  • Network Management Tools (v73.25)
  • SATAIDE Driver (v11.1.0.43) WHQL
  • SATARAID Driver (v11.1.0.43) WHQL
  • RAIDTOOL Application (v11.1.0.43) WHQL- you can install this one if running RAID
  • SMBUS Driver (v4.79) WHQL
  • SMU Driver (v2.08) WHQL
  • GPU Driver (v197.13) WHQL
  • PhysX (v9.10.0129)
  • Away Mode Driver (v6.0.6000.115) WHQL
  • Installer (v8.36)
That will fix the coprocessor driver, and hopefully then also allow CPU-z to see the make and model of the motherboard. If that doesn't work the only way to find out is to open the case and look for it printed on the motherboard (still need that for the audio driver).

Before going that far let's see if it can't be found a little easier. Open Device manager and double click on the "High Definition Audio Device" and then click on the Details tab. From the dropdown list select Hardware IDs and post back what it shows.

Okay, under Details tab all it says is

"High Definition Audio Device"

under that it says

Property -
Device Description (there is a pull-down menu here)

Under that all it says is High Definition Audio Device

That's all.

Okay here's what it says under Hardware Ids,



If you can't tell, all of it didn't fit within the screenshot, the rest was EV_1001 on the first one. I have no idea what this stuff means by the way, lol.

About normal for Realtek's dial up (or so it seems) connection. You can also find links for it here,

Realtek HD Audio 2.60 audio driver download from Guru3D.com

that will download much faster.
