I have a 15-eh0017na purchased direct from HP with the same issue after it updated to Win 11, plus I believe there was an automated update to the BIOS from HP on shutdown(?). I've tried most things that have been suggested as a solution to no avail. I have some additional observations that may help a HP Support Agent.
Using the internal speakers. The master volume behaves as described by Cuthbec. In addition, the F6/F7 keys behave the same as the system volume slider control, although F5 mutes the sound as normal. Using an external mouse, hovering over the taskbar speaker icon and scrolling does nothing. Individual app volume controls work as expected, so these are the only way to control the volume.

Using wired headphones, the situation changes, so that the master volume controls all behave correctly, but the individual app volume controls do nothing.

Using bluetooth headphones all controls behave correctly.

This seems to suggest a driver issue but I have the up to date Realtek audio driver installed and no roll back option apart from rolling the whole system back to Win10. Another post suggested it could be the AMD Audio CoProcessor Driver, but I can find no way to update this.

Update to the above a few days later ...
I installed Driver Booster 10.1 free edition, updated all drivers it suggested and the audio issues are now fixed. It seems that software does a much better job than the online HP tool or AMDs offering. Btw, the AMD Audio CoProcessor Driver supports audio on HDMI, so nothing to do with the internal speakers or Bluetooth.
