Cannot change volume when I'm using my All-in-one PC as an output screen for Nintendo Switch console

[Guidjet]

I use my Envy 23xt All-in-one desktop as the monitor when I'm gaming on my Nintendo Switch console. I used to be able to increase or decrease the audio when I am gaming using the volume keys on the keyboard and the ones on the sides of the monitor. However, I am now only able to mute by pressing the mute button on the keyboard or unmute when I press the increase or decrease volume buttons on the keyboard. So now, the audio is stuck on a low level when I am gaming and does not change no matter what I do. This wasn't always the case as I used to be able to change the volume but for some reason now I cannot. Note that there are no volume issues when I'm using the actual computer and when I'm not using it as an HDMI output.

Thank you for your response, I updated my Windows 8 and as for HP Support Assistant, there were no updates. And this is what I got when I ran SFC scan. Anyhow, the issue remains unsolved.

Let's do a system restore: 

1) Save any open files and close all open programs.

2) In Windows, search for restore, and then open Create a restore point from the results list.

3) On the System Protection tab, click System Restore.

4) Click Next.

5) Click the Restore Point that you want to use, then click Next.

6) Click Finish to restore your computer to a previous point.

7) Do not interrupt System Restore when it starts. This can corrupt your hard drive and create more problems. 😎 Click Yes in the warning that appears.

9) System Restore returns the computer configuration to a previous point in time and restarts.

PS: Performing a system restore will not delete any files.

I followed the steps, but the only system restore point was on July 23rd which was too recent. Nonetheless, I went through with the system restore process and the issue hasn't been resolved.

When the Nintendo is connected we will need to enable the Nintendo as default audio playback. Try this and let me know if this works.

This is the audio playback window while the Nintendo is connected and switched on. It doesn't show the Nintendo.

If the System Restore didn't work please try a Reset and then run all the Windows and HPSA updates
