Need help on audio for HP Envy Bang & Olufsen

[RPajooh]

Hello,  my computer recently had to reboot. Had some kind of crash and I had to restore it to factory settings.  I did this buy myself because well...let's say that 2 year warranty at geek squad is a joke. Appreciate them making me wait over an hour to only try to charge me over $150 for a system restore (that I can do by myself), and when I have a 2 year warranty. Anyways, rant aside, the computer rebooted just fine albeit I lost my work files. However, the sound is now terrible. This system did not have the best speakers to begin with but now it sounds like everything is at 25% of what it used to be at.

I've checked the drivers and all that and it appears it has the most up to date driver (Conexant ISST Audio).  I considered going back to an earlier driver but I know the earlier drivers had security issues.

I've spent hours fiddling with settings and all that and still have not had any luck.  Especially, voices, I have such a hard time hearing people talk on youtube and whatnot. Which is a shame because I love to listen to podcasts while I work.

Can someone please help?  I spent over $1600 dolllars on this laptop barely over a year ago and it's a shame that I'm having troubles already. I already returned it once before because the first one I got the speakers did not work at all. You would think a computer that markets itself as an audio type computer with "Bang and Olufsen" experience that it would have amazing speakers and audio but it does not.

Hi.

Update the bios: https://support.hp.com/us-en/document/c00042629

Use:

http://aka.ms/diag_audio10

http://aka.ms/diag_device

Press the Windows key (+) X / Device Manager / Sound and video controllers / select the audio driver you have and right click on it, then choose the properties option / Driver / Revert to the previous driver.

Wow, thank you so much. Your advice is better than the 300 dollar warranty I have at Geek Squad. Updating the bios based off my computers serial number and information and updating the sound worked!

What gets me is that i checked for updates manually, you know like when you go to the driver? Yet there are updates on the HP page that don't automatically pull in. I don't get that? You would think these important updates would be automatic.

Anyways...thank you so very much!!!! It worked!
