No Output-Device found

[Sunstar]

Hi,
I enabled audio for macOS-Guest, Host Audio Driver: Coreaudio, AudioController: Intel HD Audio. Problem is that macOS says in setting: "No output-devices found", I also changed it to ICH AC97, but it didn't helped.

How to enable audio?

With the VM shut down completely (not paused or saved), right-click on the VirtualBox Manager and select "Show Log". Save the first "VBox.log" only, ZIP it and attach it in your response (see the "Upload attachment" tab below the reply form).

Okay, done

00:00:09.733646 Guest OS type: 'MacOS_64'

VM Settings » General » Basic » Change the version to OSX 10.11, not the generic OSX. It's the closest to 10.12 that you have.

00:00:09.708016 Host RAM: 8192MB (8.0GB) total, 3548MB (3.4GB) available
00:00:09.825960   RamSize           <integer> = 0x0000000100000000 (4 294 967 296, 4 096 MB, 4 GB)

You are assigning memory to your guest, that you do not have available. Either close some applications on the host, buy more RAM for the host, or reduce the amount of RAM assigned to the guest to 3072MB (3GB). Mine runs fine with that.

Any really good explanation why you change the System » Motherboard » Chipset to PIIX3 from ICH9, which is required for OSX, as it says in the tooltip, the manual and everywhere else that you see that chipset mentioned?

Hi,
thank you! After I adapted the points you mentioned I see the output devices. The problem is that the sound I hear has many other noises and the sound is much deeper and slower than it originally is. Do you know the solution for this problem?

[socratis]

You didn't answer my question about the chipset. If you want me to answer your questions, you should be answering mine as well, don't you think?

Hint: It was the ICH9 chipset that fixed it...

You didn't answer my question about the chipset.

Yeah, sorry, I thought it is not so important, but some months before I also set up a VM with macOS. After starting nothing bootet and the VM-screen stayed black. So I searched and found the tip with changing the chipset, then it worked. So I thought this is a necessary process.

So, what is no about the sound? It has many other noises (so it means the quality is bad), also it is very deep and slow, how to "fix" that?

That's what I thought, that's why I asked for verification. This tip applies to Hackintosh-based installations.

what is no about the sound?

Sound is problematic. Has been and will be for the near future. Actually any process that relies on exact timing/timers is problematic in any VM. They tried to put a new sound engine in the 5.1.x series but it created a lot more of problems than it actually solved and in 5.1.10, they reverted part of the code to the 5.0.x series. From the release notes of 5.1.10:

• Audio: fixed a few 5.1.x regressions by using the audio code from 5.0.x until the audio overhaul is completed
