B&O cannot connect to RPC server

[Florio60]

I've seen that this topic has already been posted here more than once, but I can't see that it has ever been solved.

My laptop is 6 months old and is working very well, but today I wanted to check the audio settings and was unable to open the B&O app from Start. I received the message "B&O cannot connect to RPC server".  I have done Windows updates, uninstalled and reinstalled all audio drivers, and have even updated the BIOS, but none of this has made any difference. About the only thing I haven't tried is to uninstall and reinstall B&O. Is that a viable option? Any other ideas?

Thank you for posting on the HP Support Community.

To get the answer to this question, B&O software is outdated and replaced with the Realtek High-Definition Audio Driver (Windows 10 v1909)

Click here: https://support.hp.com/in-en/drivers/selfservice/swdetails/hp-envy-17-ce0000-laptop-pc-series/260847... to download the new audio driver for your computer. 

Hope this helps! Keep me posted for further assistance.

Many thanks for your reply, Echo_Lake. I have already tried this solution; it does work for a while, but then the B&O audio control app won't open any more, and I get the 'B&O cannot connect to RPC server' message. If I reinstall the latest Realtek drivers, the problem is revolved again, but only for a short time.

I've seen that my version of the B&O app is 1.8.203.0, whereas I've been told that the latest version is 1.9.212.0 ; it doesn't update automatically when I update the Realtek drivers, and I cannot find a way of updating it manually. Do you know how to do this? I am sure that this is the only way of solving the problem.
