pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD 6600 XT

@pastrychef I've suddenly started having bluetooth audio (other bluetooth devices, like magic trackpad seem to work just fine) issues, where the audio played via bluetooth headphones or bluetooth speaker stutters terribly. Sometimes it starts right after rebooting, sometimes it's fine for few hours and starts after some time, but once it starts it stays this way.

I've tested both audio devices with iphone in the same place where the hackintosh stays and both work flawlessly, so it's not the devices nor 'busy' radio spectrum.

Any ideas what could cause that?

Since it's an intermittent problem, I highly doubt it's a Clover configuration issue.

If/when it happens, hold the Option key and click on the Bluetooth icon in the menu bar. Then scroll down to your audio device and check the "RSSI".

As I said, I am pretty sure it's not about the signal strenght - the speaker is about 1 meter away from the computer and the RSSI is reported to be -38 to 40dBm. It was also working great until some time ago, so either OS update or one of the folders (kexts and so on) must have caused that.

I don't have anything in my EFI folders that affect Bluetooth. No kexts, no patches, nothing. It's all handled natively by macOS.

You can try using a USB Bluetooth adaptor and disabling the the internal Bluetooth via BIOS to test if is the BCM94360CS2 card itself.

Are you using your Wi-Fi/Bluetooth card in the motherboard M.2 slot or are you using a PCI-e adaptor?

I'm using a M2 card slotted via adaptor into the PCI-e. So fat it's been working as good as native chip (wake on use bt devices and so on).

The PCI-e adaptors require that a cable to connected to a USB header for Bluetooth to be functional. I'm wondering if that cable is getting interference due to lack of RF shielding...

If it would be something physical, then it would be like that from the beginning, and as I said it used to work just fine. Also, other non-audio bt devices would've had issues and they don't. I really think it's something about divers or settings or the OS...

You can try an older version of Clover or macOS to test.

Well, its' possible that it's an issue with drivers, and that's more likely. Still, there's an outside chance you might be facing a hardware issue - as in some component is starting to fail. Intermittent failures are very difficult to resolve. Something to consider if you've checked all the drivers and other issues and can't find a solution....
