Everything works as it should except the Line-Out port. Player doesn’t react to anything plugged into this port. No settings to enable. Player shipped with v1.6 and was downgraded to v1.5 before installing rockbox. Been over the settings multiple times. Even though the players firmware has been downgraded to version 1.5, line-out functionality works in the original firmware. I tested it then rebooted back into rockbox. Line-out worked perfectly until I switched back to the headphone jack. Then it didn’t work. Am I missing something?
