Audio system on 840 G6 with disabled ME

[pianisteg]

840 G6 has very tasty feature — it allows to disable Intel ME from bios. No soldering anymore! 🙂

Nevertheless, if you disable ME, you will loose digital internal mic. On my system (Ubuntu 20.10) dmesg shows timeout error while uploading firmware.

Looks strange, why does audio system require ME to be enabled?

PS: Of course, you can disable internal mic, but I want to have Bang & Olufsen internal mic working. 😞

Hi,

strange.

As per Wikipedia: https://en.wikipedia.org/wiki/Intel_Management_Engine#cite_note-31

Seems it's a security and related with DRM and it's as per design and not recommended by Intel and disabling ME disables Audio and may be other functionality.

still Upgrade BIOS if it is not.

As mentioned you are using linux, you can refer link: https://www.hp.com/us-en/shop/tech-takes/how-to-update-bios-software

Refer to section: "If Windows is not able to start:"

Hope this helps

Thanks & Regards
