HP Audio Control cannot access the RCP service

[Gabriel_LC]

My new Laptop HP Pavilion Laptop 15-cw1xxx with Windows 10, has a problem with the HP Audio Control App, for when I try to open it a message shows saying: "It is not possible to establish a connection with the RCP service".

I have to say that I already did some modifications to the RealTek Audio Driver because I couldn't find an equalizer in the computer, but I think that's the reason why now I can't use that application.

Please help me, I wanna know what to do and if it's fixable.

Hi @Gabriel_LC

Welcome to the HP Support Community. I'd be happy to assist you with the audio issue. 

Let's try these steps - 

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).

Hope this helps! Keep me posted.
