Hdac0: Unexpected unsolicited response from address 0: 00000000



  • My PfSense box is constantly writing this message in the error log every few seconds. I think this is a sound card related error but have found no solution to fix this. All packages in PfSense are up to date.

    "hdac0: Unexpected unsolicited response from address 0: 00000000"

    Some users have suggested disabling the sound card in BIOS. However, I would like to keep the sound card enable so that I could hear the lovely bootup and shutdown tone.

    Any advice will be appreciated.

    The startup/shutdown beeps use the PC Speaker and not a sound card. Disable the sound card.
