No 2.1 audio channels

[behindyouu]

Hello I just bought a 2.1 Logitech speakers. The problem is, there is no bass going to the subwoofer, and also there is no option to select 2.1 audio channel.

Other info.

• Subwoofer is connected to AC
• If I connect my phone and play a sound, the subwoofer works.
• Realtek HD audio manager is up to date.
• Windows 7 Home premium 64 bit.

EDIT: I just found the sound & audio thread. Sorry if this is posted in the wrong forum.
EDIT2: Thank you for moving.

Have you checked all the drivers for the Realtek device(s) to make sure they are up to date(yes i see you said they are but still its good to ask)

 

[behindyouu]

Yes.

You're missing a key component on that screen. To get 2.1 sound out of the stereo jack, you need HD Audio AND the option for Full Range Speakers. To check the driver in use, click on the "I" in the lower right corner of the window. (Just above OK)

This image shows the Full Range Speaker option. I get window-rattling bass out of my cheap 2.1 system.

After clicking the "Display icon in notification area" it does not do anything.

Maybe you can help me via team viewer?

I don't do Team Viewer. "Display icon in notification area" is not what I'm looking for. Post a snip of the Information window when you click on the I. Leave everything else alone.

Here is a video.

no 2.1 - YouTube

The only thing I see is the ALC272 Codec. That supports two channel stereo which should include full range frequencies so I'm not sure why the base isn't coming through. The thing is, this must match the Chip used in your PC. Where did you get the "updated" drivers? The drivers should come only from Lenovo that match your exact PC model.

Also, please proved the complete model number for your Laptop.

I updated the drivers from this website Realtek

and my PC model number is Lenovo b570

You might try downloading and installing the drivers from Lenovo Support. They may have specific INF installers for your model. The hyperlink (blue letters) is for Canada English but you can change it using the selection at the top of the page.

Click on "Drivers and Software" under the header "CHOOSE THE SUPPORT YOU NEED".

When I try to install the drivers from Lenovo it gives me an error. I did a roll back and updated the driver but no luck.

What kind of error? What does the error say???????????????????

 

[behindyouu]

It said "Install Realtek HD driver failur!!". I think the error showing because I am downgrading from 6.0 to 5.0

Error code 235 used to mean corrupt system files. Reboot and run sfc /scannow from an elevated command prompt. If the console doesn't report any errors, uninstall the driver (through device manager - hardware properties) then reboot again. Try to install the Lenovo driver. If you get the same error, download the drivers again. Make sure the download completes. Also, be sure to use the correct selection. 32-bit/64-bit for Windows 7.

sfc/scannow gave me 0 errors. I tried uninstalling the driver and installing the lenovo driver but it gave me the same error. I am back to normal. Driver version 6.0.

 

[behindyouu]

Okay, I got the drivers from Lenovo to work, but now there is no Realtek HD audio manager app. I tried updating but it says it is up to date.

Click on the Start Orb and type ravcpl into the Search box. You should get two instances of a program. Don't do anything else, just see if they are there.

 

[behindyouu]

i dont see anything when i type ravcpl

 

[behindyouu]

I found the full range speakers option, but subwoofer is still not working
