Imac 2017 no audio

[-Max-]

This is my first attempt at getting Linux running on my Imac retina 27" 2017. I have completely removed OSX and installed Linux mint 20.0 (Cinnamon), which went fine. Most things seems to be working, except audio, where I get no sound at all. I can also see from the forum, that I'm not alone, but most posts seems to be from last year.

I should probably mention that my Linux skills are fairly.... well unskilled.

I've tried including what I think might be relevant outputs.

I'd be very grateful, if anybody could help me out here.

Anyone please ??

[Pinokkio]

I am not an expert , but sometimes one oversees the most simple thing ( for example the computer or TV doesn't start anymore and then to find that the electric cable isn't connected .
So in Preferences ==> Sound are the internal speakers selected and volume up high ?

Thanks for the links Pinokkio. I will try those and see where it takes me.

[jamiemint]

All of your outputs look almost identical to mine (iMac 13,1) but my audio works. I would try "alsamixer" and see what that gives you. Up arrow increases values.

Jamie

[absque fenestris]

https://archived.forum.manjaro.org/t/so ... na/43638/8

...select "off" in the top menu that propose to setup the Digital Surround
...select Analog Surround 2.1 Output or Analog Surround 2.1 Output + Analog Stereo Input
...Now the sound works!

also an iMac 2017 ...

Hi Jamie and absque

I tried alsamixer. No dice.

I also tried the solution from manjaro, but no luck there either. Of course, I do not have a configuration page in sound mixer, but installing pavucontrol gives me the configuration page. Choosing the same values yields nothing.

I should add, that when testing the sound, the volume bar in Volume Control/Output Devices in Pavucontrol shows output (the VU meter bar flickers), but no sound from the speakers.

[absque fenestris]

Hi Max
I don't know if it fixes the annoying fault, but try all the tips that forum member Portreve has listed.
Maybe just resetting the parameter RAM will help.

[jamiemint]

I should add, that when testing the sound, the volume bar in Volume Control/Output Devices in Pavucontrol shows output (the VU meter bar flickers), but no sound from the speakers.

Well, if that's the case, it sounds more like a hardware issue. Can you plug in an old pair of speakers or headphones and change the Output Device?

Jamie

[-Max-]

Thanks both for the suggestions.

I tried running through the link suggestions, but to no avail. I also tried with headphones. The headphones seems to get registered, I see the flickering VU bar in the sound settings, but still no sound.

I have also tried steps 1 to 6 in the "No sound Fix Tips" in the link, but no sound so far

[MrEen]

Hi -Max-,

Let's get a look at your sound setup with this command:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

The last line of output will have a URL pointing to the info. Pasting that URL is all I need.

EDIT: Whoops, you already did that! I'll try going through the output and see if I can spot something out of place. In your PM, you mentioned another thread with a less-than-ideal solution. Just in case, do you still have a link to that other thread?

[MrEen]

Looking though the output so far has revealed one thing to note. You have 2 speaker pins instead of just one, so this might make a difference:

On the Configuration tab of pavucontrol change the Analog Stereo Duplex setting to one of the Surround options then test your sound. Your lack of headphone sound indicates this may not make any difference, but I'd like you try it anyway.

I'll try to keep looking through the output for anything else amiss, but my time is a bit limited.

[MrEen]

And when that fails, see my post here and try the same things: viewtopic.php?p=1878491#p1878491

Regardless of which configuration profile, I choose, whether it is Stereo Duplex or any of the surround options, I get no sound. On the "Output Devices" tab I do see the VU sound indicator bar move.

I'll move on to the next suggestion

[-Max-]

And when that fails, see my post here and try the same things: viewtopic.php?p=1878491#p1878491

I tried the 3 code fixes in the post, with reboots afterwards, but no success, regardless of configuration in pavucontrol. VU bar in pavucontrol shows activity under all 3 commands.

So no luck so far.

Okay, I'm assuming one of those edits is still in place, so please run this again while trying to play something with sound so I can see if we've made any progress at all:

I still see nothing unusual. Remove the last edit with this:

Code: Select all

sudo rm /etc/modprobe.d/mac-fix.conf

Reboot and test your sound just in case. When it still doesn't work, try suspending the machine then waking it back up and test the sound again.

I tried running the code, and rebooted. Result:No sound from speakers or headphones. Suspended the machine and logged on again. Result: No audio from speakers or headphones. VU bar in pavucontrol/Output Devices/Speakers still shows activity.
