Try to use a good driver updater software like advanced driver updater to update your camera and sound driver.

Did sound and camera work before?
Did you do a BIOS update, and it failed after that?
If yes, how did you perform the BIOS update? I have the same laptop (PA14250) and did a BIOS upgrade via the Linux fwupd system, which uses the UEFI capsule method. This caused the audio and webcam to fail on the next boot, because of the system ACPI tables: They reported that the system has a Realtek audio device, while in reality it has a Cirrus Logic one.
I was able to restore both audio and webcam by using the BIOS' own update method: Pressing F12 while booting and selecting "Update BIOS" in that menu, then having a USB stick with the BIOS update EXE (not CAB) on it, and then running the firmware update that way. Afterwards, ACPI tables were correct and both audio and webcam started working again.
