Absolutely! Just download AppleALC.kext version 1.5.5 from Acidanthera. See my comments here. I'm still running Catalina as my baseline, so I'd suggest following developments in this thread, too.@deeveedee I'm still waiting for microphone update. Is there any chance for me testing this ?
I don't have this problem @rafale77. The only thing I have done when upgrading to 0.9.4 is changing the PlayChime entry from true to string Auto and the chime is working fine for me.One strange thing I noticed after the update. It seems like at each boot, macos 11.1 wants to reset the <SystemAudioVolumeDB> value in the nvram to 0 which essentially disables the OC boot chime. I have no idea why.
In case you did not know 0.6.4 enabled control of the boot chime from the macos settings audio option like a real mac using the nvram entry <StartupMute>. That part works but now I don't know what part of the update is resetting the volume value to 00.
I am editing my config.plist to lock this value...

That is not my case:That is interesting. Let me try that...
Edit:
Indeed, it appears that setting the "playchime" setting to "auto" instead of "enabled"/"True" makes OC ignore the systemvolumeDB. The OS still resets that value to 0 upon reboot though.
Sounds like a great setup! I haven't seen any other posts in this thread regarding Thunderbolt and I don't have that Flex IO port in my system. I would recommend that you search for other Thunderbolt threads (like this one) and post your questions there. In my opinion, as long as you have a supported Thunderbolt chipset, your solution won't be specific to the G5 DM, so you should be able to seek advice from others who have working Thunderbolt in different systems.Excuse me, By my G5 dm, successfully installed Big Sur,I have a hp thunderbolt 3.0 port flex io, External graphics dock(Legion BoostStation eGFX box) is connected through this port with rx5700xt graphics card,The USB ports in the graphics dock is normal, Thunderbolt displays "are Drivers no loaded" in the system information, isn't work. How to enable it?
