When multiple DAX components are running simultaneously, instance resources may be insufficient. In this case, DAX instance manager ensures that higher-priority DAX components are always granted instance resources. For DAX components that cannot obtain instance resources in a timely manner, dax_process will operate in pass-through mode.

Cherry picked from main branch: 4b1de38

It seems that zephry sdk is not correct.

Can anyone help to retry CI checks. We also need to cherry pick #10728 from main branch once this change is merged to support DAX on headphone.

In this case 008 is fine (zephyr updated last week)
