  2. Is there a microphone driver or microphone EFI for Lenovo E470 opencore?

  3. 2 x comments: Microphone is under the control of the audio driver, whether you use AppleALC (which works with AppleHDA) or VoodooHDA (which disables AppleHDA). Then, it's down to a matter of the kexts having the correct definitions for the Codec. No such thing as a "microphone EFI". Please search the forum before posting as your issue has already been reported and addressed here.

  6. Nothing weird with having no Bluetooth working if that's what you meant. Would be a Qualcomm Atheros module too and those were also finicky when not plain unsupported. https://wikidevi.wi-cat.ru/Qualcomm_Atheros_QCNFA435 Replace that unsupported QCA card by a supported Broadcom model.

  7. WIfi: Qualcomm Atheros QCA9377. I have no wifi which is expected, but I don't have bluetooth which is weird. Audio: Conexant CX20753/4. I can see audio input level changes when I speak, but there is no sound out.

  9. @Max.1974 thanks for the EFI, I was able to install Big Sur 11.2 on my E470. But I don't have Bluetooth and no sound (I can see microphone input level changes when I speak, but no audio out). Could you please help. My EFI is attached. I only include OpenCore in the EFI for small size. EFI.zip
