All other hot keys appear to function properly, only the mute/audio-/audio+ hot keys do not work.
I can press the key and the vertical volume indicator displays but it does not move.
At this time, I suspect this has to do with the failed BIOS update yesterday. All keys functioned properly before the failed BIOS update.
All HP drivers and software are updated to latest.
Another symptom I don't know may be related is that my bluetooth headphones have refused to connect once now without a full reboot. Bluetooth would connect and speaker audio audio would be muted, and sometimes "Manage Audio Devices" indicated connected to headphones but no headphone audo. Will warrant further watching.
The BIOS update was the most recent as of this writing and attenmpted to update only yesterday. I watched as the new BIOS progressed all the way to the point the BIOS attemnpted to flash and failed, then rolled back. I assume a backup was flashed because all my non-default BIOS settings had to be reset (non-UEFI boot, enable virtualization).
TIA,
Tony
