HP Audio Control Can not connect to RCP services

[seearghee]

Have late 2019 Spectre X360.  HP Audio Control worked when I first set up the computer, but now get the message "can not connect to RCP services" when I try to use it.  I did manage to get it to work by uninstalling the Realtek driver & then doing a restart to install it again, but when I turned the computer off & then restarted I received the  "can not connect to RCP services" again when trying to use HP Audio Control.  Would like to get this fixed, as I find the audio awful without the additional controls provided by the HP Audio Control consol.

Thanks

@seearghee Let's resolve one issue at a time, starting with the RPC error:

Ensure your RPC services are running properly

“The RPC server is unavailable” problem can be caused by improper functioning of RPC service on every computers connected. You may follow the steps below to ensure that all the services related to RPC run normally.

1) Press the Windows logo key and R on your keyboard to open the Rundialog. Then type “services.msc” and press Enter.

2) On the Services window, scroll down to find the items DCOM Server Process Launcher, Remote Procedure Call (RPC) and RPC Endpoint Mapper. Ensure their status is Running and their startup is set to Automatic. 

Firewalls can block traffic requested by RPC and therefore cause RPC server unavailable problem. You should check your firewall configuration and see if it blocks the network connections for RPC. If you are using a third-party firewall, read its instruction or do some research about it to unblock the RPC network connections. 

If you are using Windows Firewall, here are the steps of its configuration:

1) Press the Windows logo key and R on your keyboard to open the Run dialog. Then type “control“ and press Enter. 

2) On Control Panel, search windows firewall. And then click Allow an app through Windows Firewall below Windows Firewall.

3) Scroll down to find Remote Assistance. Ensure its communication is enabled (All the boxes of this item are ticked).

Thanks for the suggestions, much appreciated.  Before your reply, I found I had disabled the Realtech HD Audio Universal Service in the Startup tab of Task Manager, in the mistaken belief that it would start up when I manually launched the Audio Control.  Enabling it in the Startup tab solved the problem, all works fine now.

Thanks, Chris
