[SOLVED] unable to set I2S in Audio Output Device

[Tim Curtis]

If it's showing Headphone it means the "Integrated audio" setting on System Config is set to "Firmware mode (Legacy).

Set it back to Kernel mode (Default) and see if the DAC shows up in the list.

If not then reboot and then post the contents of the startup log.

The log can be viewed via the SSH command moodeutl -l or downloaded via the Logs section in System Config, or via Menu, System info from any of the Config screens. The startup log will be at the end of System info output.
