Audio problem following bios upgrade

[RichardLDSA]

I installed a bios upgrade required by support assistant. Now Windows 10 cannot find my internal speakers and microphone. When I use external speakers they work. There was no problem prior to the bios upgrade.

Welcome to the HP Forums,

I recommend you recover the last working BIOS version:

Perform a series of keyboard presses to launch an automatic BIOS recovery.

This option is available for many HP computers with a functioning hard drive.
 

Restoring the BIOS on HP Computers with a KeyPress Combination

Learn how to restore the BIOS on your HP computer with a key press combination.

1. Turn off the computer, and then connect the power cord.

2. Press and hold the Windows key  and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.

3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

   The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.
    

   
    

   • If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.

   • If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.

   • If a BIOS recovery message repeatedly displays, continue to the next step to install an updated BIOS version.

   • If a message that the computer improperly shut down or a boot problem is detected displays, follow the on-screen instructions to resolve the error.

   • If Windows starts, update to the latest BIOS version. Go to HP Notebook PCs - Updating the BIOS.

I attempted by ways, and it stil lhasnt fixed the issue.  I still have no access to speakers / microphone, and there is still no sound thru the HDMI cable.  bluetooth speakers work, and external camera/ microphone does work.  

What is the next step?  I saw one pace where they recommended taking it back to factory installed Bios

[RichardLDSA]

I tried those suggestions and none of them worked. I couldn't reset the bios. I tried to download a new bios but the instructions for getting the identifying information didn't work.

@RichardLDSA & @RichBing I appreciate the details, I suggest you check this related post on resolving issues post BIOS update: Click here to view it. (It's an old post, however, the solution would apply to your concern), also, if that doesn't work, please make use of the HP Recovery manager: click here for instructions, the same should help recover the original drivers for your audio device using the driver recovery function.

@RichBing I understand it hasn't helped yet, however, that's how troubleshooting works, we try one thing and if that doesn't work we try another until its resolved, that out of the way, I appreciate your patience and perseverance, I recommend you perform a test on the audio card to be sure this isn't a hardware issue: Click here for details.

If the tests pass, you may want to back up the personal data and perform a system recovery using the instructions mentioned here.

Keep us posted,

 thank you for the follow-up.  Hardware test showed no audio issues.  I performed a sytem reset, where i went thru the windows 10 software and reset to installation version windows 10, while keeping my persoal files etc.  The speakers now work.  Thank you for the help
