[PROBLEM] Headphone jack output not working on HifiBerry DAC2 Pro

[leokeba]

Hi, I installed Moode on a Raspberry Pi 4 equipped with a HifiBerry DAC2 Pro Hat, everything is working as expected, except the headphone jack output which does nothing. 

I have tried many things, including the workaround described here : https://support.hifiberry.com/hc/en-us/c...headphones

But I get the following error trying to use the i2cset command : 

Code:

Error: Could not set address to 0x60: Device or resource busy

I even tried to update the kernel so I can use the latest dtoverlay as hinted here : https://www.hifiberry.com/docs/data-shee...-dac2-pro/

One important thing to note is that the jack output was working perfectly using LibreElec on the same raspberry pi board wired the exact same way, so this is not a hardware issue.

I'm out of ideas, last resort will be to abandon Moode and go back to LibreElec but I really liked the features, so does anybody have a suggestion on what to try next ?

TIA

Hi leokeba,
welcome on board. 
Probably, if your issue is linked to the kernel version only, it should be solved with the next moOde release.
The current release is:

Code:

Release 8.3.9 2024-02-23
RPiOS: 11.9 Bullseye 64-bit | Linux: 6.1.21

The next release will be:

Code:

Release 9.0.0 2024-MM-DD
RPiOS: 12.5 Bookworm 64-bit | Linux: 6.6.28

If you like to have any more infoes (including prerelease link), please find them in this thread.
Best regards,
Francesco

Thanks,

I don't think the issue is only related to the kernel version because updating it over the 8.3.9 release with rpi-update did not fix the issue even though the correct dtoverlay (hifiberry-dacplus-pro) was indeed present after the update. 

But the bookworm pre-release does indeed fix the issue, so I guess I will keep using it until the stable version is released.
