Envy 17 not seeing my speakers (B&O)

[Houmous]

Hi Guys

My inbuilt speakers (B&O) have stopped working in Windows. "no audio devices found" is shown when I right click the speaker icon in the task bar. 

In Device Manager "Intel smart sound technology OED" has a warning triangle but when I try and update or change it tells me I have the latest update and gives no alternative. I have tried deleting it but it returns after I reboot. There does not appear to be any driver installed that I would associate with inbuilt speakers such as Realtec HD drivers.

I have run all the HP assistant diagnostics but they have not helped. 

(I ran the audio test on the HP BIOS based diagnostic tool and the speakers work fine)

Can you help please?  Thanks!

The only driver shown as installed in Device manager (under Sound video and game controllers) is cirrus logic awesome speaker amps (show hidden devices is active). If I uninstall it its back after I reboot. I have tried to install Realtek HD audio driver in the hope it will find the internal B&O speakers but they will not install. After clicking install the zip file extracts then I get a rotating circle for 10 seconds then nothing!

Hello Houmous, go to the device manager and the driver that is in yellow, click on the right mouse button and search for drivers automatically, click on examine my computer for drivers, you will see the drivers you have to install.
I also leave you the Bang & Olufsen download link

Hi Jos1.  Thanks for your reply.

Unfortunately when I right click on Intel Smart Technology OED driver and follow your instructions it just gives me the same driver as an option and then says it cant install it - error code 10. 

I downloaded extracted and installed  the B&O driver you sent me but I cannot see it listed in Device Manager and my PC still cannot see my internal B&O speakers. When I try and run the B&O audio control app it says cannot connect to RPC service.

Can you advise? Many thanks.

Hello Houmous, I am going to leave you a download link that is compressed, create a new folder in documents or wherever you choose, there in that folder extract the compressed files, then go to Control Panel, Device Manager, display, sound controllers and video and gaming devices, in the Conexant ISST audio driver, right click and update driver, do not click on update automatically, click on Browse my PC for drivers, on the next screen, in browse, enter the address where the folder is and click on the option, choose from a list of drivers available on the computer. The driver must appear to install, just check it and install the driver. I leave you two drivers links and create two different folders to unzip, then follow the steps I have indicated.

Hi Jos1. Thanks for coming back so quickly.

I only have one audio driver showing in the" Sound controllers......." category. "cirrus logic awesome speaker amps". Should I try and install over this? Which driver on your pack should I use to do this?

Thanks

Hello Houmous, you're welcome, it's a pleasure to help you, create two different folders to extract the contents of the two compressed files that you have downloaded, one you can name bos and the other Bang, extract each compressed file in each folder and then Follow the steps that I have told you, device manager and update, examine my PC for drivers and install the driver that appears.

Hi Jos1.

Thanks for your reply.

I only have one  non bluetooth driver showing under "Sound video and game controllers" which is "Cirrus Logic Awesome Speaker Amps".

I have downloaded and extracted your files but when I try and update the Cirrus Logic Awesome Speaker Amps driver, following  your instructions and entering the location of either of the two extracted files I just get "best driver already installed." (see screenshots).

Can you advise please? Do I need to install an additional new driver from your folder first? Thanks.

Hello Houmous, sorry but it is difficult to find the driver, I finally managed to find it and I hope it installs it for you because it includes Bang & Olufsen. It is compressed and you have to unzip it, many compressed files will appear inside, a folder will appear and you will create one with the name Bang & Olufsen so that you do not make a mistake, there you go unzipping the folders as I have told you and it should appear the Bang & Olufsen.exe application to install.
I leave you the link and if you don't know something, tell me. I hope you can install Bang & Olufsen.

Hi Jos1

Thanks for your message. I have extracted the file you sent me but the only exe file it contains is UIU64a.exe.

Is this the one you want me to install?
