iMac 2017 interne audio (CS8409) ontbreekt, alleen HDMI werkt

Hallo,

Op een iMac 2017 (iMac18,3) met Arch Linux werkt alleen HDMI-audio.
Interne speakers verschijnen niet als device.

Hardware
Codec: Cirrus Logic CS8409

Status

snd_hda_intel driver geladen

PipeWire actief

aplay -l toont alleen HDMI devices

Kernel: 6.12.70-1-lts

lspci -k toont:
Intel HD Audio controller → snd_hda_intel
AMD HDMI audio → snd_hda_intel

Het lijkt erop dat de codec wel wordt gedetecteerd maar de interne output niet wordt geïnitialiseerd.

Is dit een bekende beperking van CS8409 support onder Linux, of bestaat er een patch/workaround?

Alvast bedankt.

Hello, On an iMac 2017 (iMac18,3) with Arch Linux, only HDMI audio will work. Internal speakers do not appear as a device. Hardware Codec: Cirrus Logic CS8409 Status snd_hda_intel driver loaded PipeWire active aplay -l only shows HDMI devices Kernel: 6.12.70-1-lts lspci -k shows: Intel HD Audio Controller → snd_hda_intel AMD HDMI audio → snd_hda_intel It seems that the codec is detected but the internal output is not initialized. Is this a known limitation of CS8409 support under Linux, or is there a patch/workaround? Thanks in advance.

Google Translator said translated this, and There is an out-of-tree codec patch that adds CS8409 support: https://github.com/egorenar/snd-hda-codec-cs8409...

Hello,
Thank you very much for your helpful reply and for pointing me to the patch. I am happy to report that it is now working. After applying the CS8409 patch, the internal speakers are detected and audio works correctly.
I really appreciate your help.
