Lunar lake audio no advanced options (for things like eac3) in pavucontrol

gguerin · April 17, 2026, 3:35pm

Hello,

Using a Lenovo x9-15 laptop with Intel Lunar Lake HD audio on Fedora 43 I can’t see any way to enable hdmi eac3/dts/etc. passthrough in pavucontrol. This is usually activated in the Output Devices tab for devices that support digital outputs (which normally applies to HDMI outputs), under the “Show advanced option” sub menu of the device.

I could see those option on the HDMI outputs with my old laptop. Also if I plug-in an external sound card which supports digital outputs then I can see those options for that device (unfortunately some codecs like eac3 and atmos can only be received through hdmi so using an external sound card is not a solution).

All sounds work perfectly fine otherwise.

Thank you for your help.

Hello, thank you for your reply. Yes I had seen this wiki before. I went back and tried some more manual settings to assign the codecs to the audio sinks using pactl but unfortunately it doesn’t work.

When using pw-cli instead of pactl I cannot see any iec958 profiles.

It looks like you are using a SOF driver. You might need to install additional firmware packages to get full functionality with that driver.^[1]

wiki.archlinux.org

Firmware - Advanced Linux Sound Architecture - ArchWiki

The Sound Open Firmware (SOF) (sof-firmware) is usually required for laptops—they tend to utilize Cadence Tensilica Xtensa architecture DSPs, see the list of the supported platforms. In case of the missing firmware the journal will provide messages...

Also, did you check for muted or disabled digital outputs in alsamixer?

gguerin · April 28, 2026, 1:35pm

Thank you for your reply. I had some of the other firmware installed and I had checked alsamixer already, and couldn’t see anything obviously wrong there.

I wonder if the sof driver just doesn’t support parse advanced codecs like eac3 and such, but it would seems strange. Also it seems to be the only audio driver for Lunar Lake Laptops…

It really feels like the passthrough on digital output is somehow not detected (even though it is through hdmi).

I’ll see if anything changes with Fedora 44 and report here.
