We have had a Macbook Air (A1466) laying around for years after it became useless due to not getting any more updates so modern browsers wouldn’t run, etc. etc.
Today I decided to dust it off and install Ubuntu - that all went great. No issues with wifi drivers or anything. The only issues I am having are that I have no audio input or output (only device available is “dummy output”) and no webcam.
I’m not really sure where to start. I have used linux before, but it has been years (Ubuntu 11 or 12 was the latest I ever touched).
Any suggestions?
EDIT:
This is what I get from running lspci -V

Have you read this? https://wiki.debian.org/InstallingDebianOn/Apple/MacBookAir/6-2
There is a link to the webcam kernel module there: https://github.com/patjak/facetimehd/wiki
Thank you! The webcam is working fine now. still can’t figure out the audio but I’ll keep messing with it
Does
alsamixerallow you to change to the correct soundcard? What doespacmd list-cardsoutput?I was able to get alsamixer to show the HDMI audio output by adding
options snd-hda-intel model=genericto the alsa-base.conf file, but that is all it can see, and that doesn’t utilize the speakers on the laptop.pacmd list-cards gives this - it looks like it is only the HDMI audio

options snd-hda-intel model=mba42(ormodel=mba6)—per kernel docs—inalsa-base.conf. This may (read: “probably will”) require a reboot for each model.Should this not work: we may have to dig into
dmesgto figure out where it’s erroring. This is currently beyond my remote troubleshooting ability (I don’t know what I’m looking for, but might know it when I see it)… Also, will you please take note of the output fromlsmod | grep 'snd'during each attempt, and share what you find if they both fail?Also per the docs: do headphones still work?
Thank you! I will try that out and read through those pages. I never had sound through speakers or headphones.
I also changed to regular Debian desktop to see if that would fix the issue per the post about someone getting the same model working on plain Debian with no audio issues, but the behavior is the same. The post was a few years old so I’m guessing it’s a version difference.
I will reply back with those outputs when I have a chance to try this. Currently the laptop is kind of unwieldy to use as I accidentally broke the teackpad (or track pad cable) while replacing the keyboard so I’m waiting on parts. External inputs work I just need to clear space to set it up for troubleshooting
Didn’t have any luck setting the model - I read through those doc pages you linked and a lot of it is over my head but I think I was able to learn a few things.
At this point - I am not seeing any of the errors mentioned anywhere - I only see HDMI audio as the only card and that is displaying no errors (this laptop doesn’t have an HDMI port, only thunderbolt, and I don’t have a cable or adapter to even test if that audio is working on an external monitor) I’m not sure if Linux is incorrectly reading the internal sound card as the HDMI output, if it’s all on the same card and the internal output is not being read, or if the internal sound card is just totally not working (hardware issue) - To my knowledge there was no issue with audio on Mac OSX but this laptop hasn’t been used in a while.
I really appreciate your time and if you want to continue helping I will put more info below, but I also understand if you don’t want to think about it anymore 😄
I didn’t see any of the errors mentioned on those pages when checking dmesg (assuming that is where they would be) - I read through all the errors, nothing related to sound that I could tell, and used grep to pull out the messages containing references to snd or audio, etc:

I also ran

Thank you for the help @infeeeee@lemm.ee @BaumGeist@lemmy.ml - I believe the issue with the audio is hardware related. I reinstalled Mac OSX using the built in recovery tool and that does not detect the sound card either. So sometime in between it being used last and me installing Ubuntu on it the hardware failed. I don’t think I will bother replacing the logic board as it is a 10 year old laptop and is otherwise working just fine.
Regardless, it’s good to be using Linux again!
