Worked for me to discover the problem.

Verify the Fix: After your system reboots, log in and check the driver again:
bash
lshw -C multimedia
Look at the audio device line. It should now say driver=snd_hda_intel. If it does, check your sound in the system settings. You should now have output and input devices available.
Solution 2: If the Above Doesn't Work, Check PulseAudio/Alsa
If forcing the driver doesn't work, the issue might be with the sound server (PulseAudio) or its configuration.
Reload PulseAudio: Sometimes, the sound server just needs to be restarted to detect the hardware correctly.
bash
pulseaudio -k && pulseaudio --start
Check alsamixer: This is a command-line tool for managing audio levels. It's possible your outputs or inputs are simply muted.
Run alsamixer in the terminal.
Use the arrow keys to navigate to the "Master" and "Speaker" channels. Press the M key to unmute them if they show "MM" (muted). Use the up arrow to raise the volume.
Look for a channel called "Internal Mic" or "Capture". Make sure it is unmuted (M key) and the volume is up.
Press Esc to exit.
Solution 3: Check BIOS/UEFI Settings
HP ZBooks have an extensive BIOS. It's worth checking if there's an audio-related setting that could be interfering.
Reboot your laptop and press F10 repeatedly to enter the BIOS setup.
Look for tabs like "Advanced", "Device Options", or "Built-in Device Options".
See if there is an option for "Audio Controller" or "HD Audio". Ensure it is Enabled. Some systems have an "Audio Mode" setting; try setting it to "Standard" or "Compatible" if options are available.
Save and exit the BIOS.
Summary
Your problem is a classic case of the Linux kernel loading a modern but incompatible audio driver (snd_soc_avs) for your hardware. Solution 1 is your best bet and has a very high chance of resolving both your no-sound and no-microphone issues by forcing the use of the stable snd_hda_intel driver.
