CM5 and Rock 5C Headphone jack no audio via ES8316

#1

Running the official Debian CLI image on Rock 5B, I am unable to get the audio working on the 3.5mm headphone jack.

However running the following command works successfully but produces no audio.

speaker-test -Dhw:3,0 -c2 -t wav -w /usr/share/sounds/alsa/Front_Center.wav

Is there something extra needed in setup to get audio working via the headphone jack?

Turns of it was the cheap pair of headphones not full pushed in the 3.5mm jack on the Rock 5B.

However when testing the same on CM5 (with IO Carrier board) and Rock 5C I get the following error.

Some further debugging, the -5 Input/output error is occuring when speaker-test is trying to write to the es8316 PCM device at line

The Overlay for the es8316 sound device setup looks ok

#4

On the CM5 with IO carrier we have some progress.

Using the official Debian Bullseye image here, sound does not work and has the above -5 Input/output error.

Using Joshua’s Ubuntu 22.04 image here sound works once you activate Left/Right Headphone Mixer Right DAC in alsamixer.

Using Radxa’s Debian Bookworm image here sound works with no problems.

#5

I suspect the issue with the Bullseye image is the Overlay for i2c8 where the clocks are initialized differently.

Versus it working in Bookworm here.

Rock 5C audio broken in desktop and server versions

@Alvin Looks like for the Rock 5C this was fixed a few hours ago on 6.1 image.

Hi，
The clk config of es8316 needs to be modified to work properly,you can modify it by referring to the commit mentioned by 3djelly.
