AppleALC : Fully working audio, Bluetooth Audio, but no bluetooth microphone

[jamesst20]

Hi,

I am currently having hard time figuring out how to get bluetooth microphone working.

My headset are Skullcandy Wireless Crusher and they work on my real Macbook Pro.

The bluetooth is provided by the motherboard.

It shows up in the input list, however the ui gets laggy and it doesn't seem to recognize any sound.



Full specs list
1x Intel - Core i7-8700 3.2GHz 6-Core Processor
1x Gigabyte - Z370 AORUS Gaming 5 (rev. 1.0) ATX LGA1151 Motherboard
1x Kingston - FURY 8GB (1 x 8GB) DDR4-2400 Memory
2x Samsung - 960 EVO 500GB M.2-2280 Solid State Drive
1x Gigabyte - Radeon RX 580 8GB Gaming 8G Video Card
1x Gigabyte - AC300W ATX Mid Tower Case
1x Corsair - TXM Gold 650W 80+ Gold Certified Semi-Modular ATX Power Supply
1x TP-Link - Archer T9E PCI-Express x1 802.11a/b/g/n/ac Wi-Fi Adapter

I attached ioreg & efi

Thank you

AppleALC has nothing to do with bluetooth audio.
Likely, USB is not configured properly.

Thank you. I already have generated an SSDT for my USB ports using this guide. I also included my Bluetooth port in the SSDT.

Are there more than one index for bluetooth ?

I will try removing my SSDT and using the USB Port Limit patch to see if it fixes.

It is possible that my SSDT makes the Audio output working over bluetooth but not the audio input ?

Thank you

Removing SSDT & Applying USB Port Limit doesn't make any difference to the Bluetooth behavior

I attached my IOReg with USB Port Limit patch enabled and here is the SSDT I built:
