No sound in MacBook Pro 2017

FrenchPress · 16 July 2021 21:24

Your keyboard is a so-called multimedia keyboard.
There is a way to make those function keys to work as regular function keys. But for the time being, please press fn key together with F6.
[edit]
You have to do this in Alsamixer window.

I already tried this.

FrenchPress · 16 July 2021 21:32

Ah, I remember that you are using Apple keyboard like myself. You can follow this tutorial I wrote for that purpose.

thomas · 16 July 2021 22:22

Thank you. I just checked and it is set to the correct sound card.

thomas · 16 July 2021 22:22

Thank you for the tutorial.

FrenchPress · 16 July 2021 22:45

I remember now.

When I was running macOS on PC, the most tricky part was a sound card. It is because real mac does not have a sound card. It is integrated in a circuit of the logic board. I solved that issue by using USB DAC.

Now the problem is in reverse direction.
Could you tell me how this "sound card" is displayed in Alsamixer?

thomas · 16 July 2021 22:46

I do not know how. It says the name of the sound card is 0 HDA Intel PCH.

FrenchPress · 16 July 2021 22:46

Are there any other option?
When you press F6, there should be a list of available sound sources. Mine looks like this:

Mine looks the same but without the available sources, only Master.

FrenchPress · 16 July 2021 23:04

and that is set to 100% volume I suppose.
I wonder if you can give me the model name of your macbook.

They should appear in Alsamixerbut clearly if you only see "Master" then there is something wrong. I remember another user posting Alsamixer showing only that. I will try and search for that thread.
If you can post a screenshot of your Alsamixer that would help.

If you can provide that info then it will also help.

In the meantime see if this thread, and the link provided there, helps you at all:

How do I find my model name of my MacBook.

FrenchPress · 17 July 2021 15:37

I know how to find it in within macOS.

But if I remembered it correctly, you removed macOS completely, no?

Aravisian · 17 July 2021 15:40

Does this support page give helpful info?

FrenchPress · 17 July 2021 15:41

I did not think of this way to identify it!
Indeed there is no need for working OS this way.

# Introduction

This is about documenting getting Linux running on the late 2016 and mid 2017 MPB's; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I'm currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).

The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials ([here](https://github.com/chisNaN/ubuntu-on-macbook12) and [here](https://nixaid.com/linux-on-macbookpro/)) focused on that distro and the MacBook.

**Note**: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore - see the updated instructions below and make sure to update your clone of the roadrunner2/macbook12-spi-driver repo to get the latest drivers.

I am afraid that making the audio working on your system is not very easy

One easy work around is using external an USB sound card - small one is very small and inexpensive (2 - 6 Euro). It is about the size of a bulky USB memory. High end desktop version would be more than 100 Euro which is of cource too big to carry around with laptop.

Great thing about Linux as well as macOS is that there is no need for installing driver for those external sound cards. Much easy to install compared with Windows.

[edit]
I change the title and category of this thread to attract more help from other forum members.

My other proposal regarding this sound issue is that you keep your macOS and install Zorin (or any other Linux OS) as a virtual machine. Virtual machines create a virtual hardware for the guest OS overcoming hardware incompatibility issues. Even you have completely uninstalled macOS, it should be easy to restore OS on the genuine Apple hardware.

Thanks for the help!
