MacMini8,1 + Mint 22 = no sound

[igorsantos07]

This could be a mild follow up to t2linux/wiki#203 lol

I've reinstalled Mint, moving to Wilma 22 with Cinnamon, a couple of months ago. Wi-Fi was working mostly fine, although now I'm not sure if it was because I had an extra Bluetooth+Wi-Fi dongle sneakily plugged in, which I forgot had Wi-Fi capabilities 😂
At some point that stopped working, though, and I came back to the wiki - then, I must say, the Wi-Fi script from the wiki was painless to use!

On the other hand, I can't get the audio jack to work, no matter what I try. Here's the information I have, given other posts I've found around:

• I tried all the different kernel lines from the Debian/Ubuntu lines - currently I'm at 6.12.4-1-t2-noble
• Easyeffects does show up as a device on the sound panel, but the best I can do is test left/right output, and it emits from the internal speaker.
• tried the script from https://wiki.t2linux.org/guides/audio-config/#audio-configuration-files
• cat /proc/cmdline yields BOOT_IMAGE=/boot/vmlinuz-6.12.4-1-t2-noble root=UUID=b35ca6bf-f93c-4d89-8051-607b2fa43340 ro quiet splash intel_iommu=on iommu=pt pcie_ports=compat
• sed -n "s/.*\(AppleT2.*\) -.*/\1/p" /proc/asound/cards yields AppleT2x1

The only thing I didn't try was editing initramfs-tools, which seemed a bit too drastic / unrelated?

You have to manually change to audio jack from settings>sounds

[igorsantos07]

Sorry for not making it clear: that's not an option. The only devices shown for me are the HDMI / DP built-in audio, and the internal speaker (which seems to vanish sometimes). If I open Easyeffects, that also shows as a device, as well as the Bluetooth speaker I'm using temporarily (the one selected in the screenshot below).

What ISO did you use?

[igorsantos07]

The original one from the Mint website. Then I installed the T2 kernel for Noble, the equivalent Ubuntu release, and many different audio packages as suggested on the wiki. Igor Santos -- Desenvolvedor web [enviado do meu celular]

Is apple-t2-audio-config installed? Also, what is pactl info

[igorsantos07]

I had to reboot and the internal speaker showed up again. The only profile it has is "Mono output":

apple-t2-audio-config was already installed, sorry for not mentioning it.

It's strange that it's not showing up. @Redecorating can you help?

[Redecorating]

Maybe check `journalctl -k --grep=audio`, there should be messages from aaudio describing what audio devices it discovered on startup.

Hope this is of any use 🙏

Seems like the driver discovers speaker output, headphone/"codec" output+input. There isn't meant to be an internal microphone right? You said you have have AppleT2x1, I think there's actually no configuration file for that here: https://github.com/kekrby/t2-better-audio/blob/main/files/profile-sets/ Maybe try this, I'm not sure if the chanel map for the headphones is meant to be mono or left,right. ``` [Mapping Speakers] device-strings = hw:%f,0 paths-output = t2-speakers channel-map = mono direction = output [Mapping Headphones] device-strings = hw:%f,1 paths-output = t2-headphones channel-map = mono direction = output [Mapping HeadsetMic] device-strings = hw:%f,2 paths-input = t2-headset-mic channel-map = mono direction = input [Profile Default] description = Default Profile output-mappings = Speakers Headphones input-mappings = HeadsetMic ```

Merry Christmas for you all, if that's your culture! 🎄

Merry Christmas!

i can't seem to make that message not have terrible formatting by editing it, let's try again here:

[Mapping Speakers]
device-strings = hw:%f,0
paths-output = t2-speakers
channel-map = mono
direction = output

[Mapping Headphones]
device-strings = hw:%f,1
paths-output = t2-headphones
channel-map = mono
direction = output

[Mapping HeadsetMic]
device-strings = hw:%f,2
paths-input = t2-headset-mic
channel-map = mono
direction = input

[Profile Default]
description = Default Profile
output-mappings = Speakers Headphones
input-mappings = HeadsetMic

[igorsantos07]

Thanks for that! No clue what you did with the markdown formatting 😂

And no, AFAIK there's no internal speaker. Not that I care for it either. The headphone jack is a single one, which should be stereo.

But also... no clue what I should do with that 😅 Could you point me to where I should place that config?

i think it may be because the message was initially sent as an email reply.

No internal speaker and no internal microphone? Or do you mean only no internal microphone ?

But also... no clue what I should do with that 😅 Could you point me to where I should place that config?

I believe it should go into these two folders (one is for pulseaudio, the other for pipewire, so having both ensures it will work for everyone) \n `/usr/share/alsa-card-profile/mixer/profile-sets` and `/usr/share/pulseaudio/alsa-mixer/profile-sets` \n normally these files are installed by this script https://github.com/kekrby/t2-better-audio/blob/main/install.sh, but you will notice this repository has no t2x1 file, which would be why it's not working

[igorsantos07]

Sorry! I said it wrong, I don't think it has an internal 🎙️

I created /usr/share/alsa-card-profile/mixer/profile-sets/apple-t2x1.conf and /usr/share/pulseaudio/alsa-mixer/profile-sets/apple-t2x1.conf, with the same contents you posted earlier. Rebooted and... nothing 😥
I see the script doesn't do anything after copying the files, either. Should I run some other command to refresh the related subsystems?

Trying to reboot again as the internal speaker didn't show up either.

[igorsantos07]

I rebooted three FOUR times in total:

1. added files, rebooted. It only showed me the HDMI output.
2. no changes; rebooted again, it took a while to boot up but other than that, same results.
3. renamed the new files so they would go missing, and rebooted once more. This time, the internal speaker is back again.
4. edited the file to say left,right in place of mono on the Speaker mapping, rebooted again, and the internal speaker is gone again (I mean, not that I care for it at all, but I guess it could mean something to you).

🤔 🤔 🤔

And btw, the only files under the alsa-mixer folder are the ones created by that script, so I guess that would be the wrong folder in my distro. But I added it to both anyway (the alsa-card-profile also includes config files for many other devices).
