Hi Jonathan Goad,
Also with Fagoon Sharma and DP,
If your laptop has Realtek audio chipset, it might be related to Realtek.
Please make sure that you have installed Realtek Audio Driver from manufactural website.
Please install "Realtek Audio Console" if you have not already done so. This is the application to manage the Realtek audio chipset built into your motherboard. You can install it by going to your motherboard's website or through the Microsoft Store.

Next, open Realtek Audio Console > Device advanced settings > toggle between Mute the rear output device, when a front headphone plugged in. and Make front and rear output devices playback two different audio streams simultaneously.
You may need to plug your headset back in after changing this setting.
Please check your audio again to see if the issue is resolved.
If this method does not help, please refer to HP Community topic:
