[Solved]Sound not working on iMac 4K

Hello everybody. I've installed ArchLinux on an iMac 4k (2015 model) and I have not sound output. I tried some other live-cd like Opensuse or Ubuntu to get a try if they could do it work, but nothing.
These are my soundcards

lluis@cajal [~]$ lspci -v | grep -i audio
00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 0a)
00:1b.0 Audio device: Intel Corporation 9 Series Chipset Family HD Audio Controller
lluis@cajal [~]$ 

It seems I've got two soundcards. I've uninstalled alsa and I've got pulseaudio only.
Some help? thanks

Re: [Solved]Sound not working on iMac 4K

What have you tried? Have you worked through the troubleshooting pages on the wiki? What makes you think uninstalling alsa is a good idea?

Re: [Solved]Sound not working on iMac 4K

I had alsa and pulseaudio both installed. An ArchLinux user in an irc told me that both don't must be installed. He told me to have only pulseaudio.
I've tried to add a /etc/modprobe.d/sound.conf like the wiki says, with my model (21,5 ; or 21 ; or 4k...I do not know how to name it) and it doesn't work

I think you hit the 'report' link, not the 'reply' link.

Re: [Solved]Sound not working on iMac 4K

I had alsa and pulseaudio both installed. Then I only had one card detected. An ArchLinux user from an irc told me that I had to choose one, so I keep pulseaudio. Now, in KDE system preferences I can see both sound cards.
I've also tried to add a /etc/modprobe.d/sound.conf file with my model as mention in https://wiki.archlinux.org/index.php/IM … work_right, but I do not know how to name it. I've tried model=24, model=21,5, model=4k ...etc but it doesn't work

aplay -lL
pacmd list-cards

For starters, and no you shouldn't try to uninstall ALSA, what the dude on IRC likely meant, was that you shouldn't have a specific config file for ALSA while using pulseaudio (if he literally meant uninstalling ALSA, well...)

Thanks for the reply.
The ArchLinux user that tried to help me, said me to specifically uninstall alsa.
The output is:

Re: [Solved]Sound not working on iMac 4K

Whoever that person was, doesn't know what he's talking about. (Maybe I should pop into the IRC and reddit as well to prevent misinformation like that from spreading...)

The "problem" here is that your default output is set to the HDMI card, and as you likely haven't configured pulseaudio yet, all applications default to play to HDMI. Go into pavucontrol and move your analog card to be the fallback sink in the output tab, move any applications that still default to HDMI to the analog card, install pulseaudio-alsa while you are at it. If using KDE you should also setup its multimediasettings so that your analog card is on top in all categories

If the problem persists even after you have done this, post

fuser -v /dev/snd/*
pacmd list-sinks
pacmd list-sink-inputs #While playing something

You might also want to add a link to the output of the alsa-info.sh script

Re: [Solved]Sound not working on iMac 4K

Thanks a lot. I installed pulseaudio-alsa and configured it. It was a mix of non-well configurations. Now HDMI is turned off and only internal audio is on, and after choose the correct profile, it's working now.
Finally it was easy to solve. I was becoming crazy.
Thanks again
