Even the IRQ registers definitely show that the FLL locked. I can only really think of a couple of options: 1) Probably the most likely option is that the clock to the FLL is being removed before you are setting up your route. Probably a reasonable thing to do next for test purposes would be to change the machine driver to use the 32k clock that should be on MCLK2 incase the high quality clock on MCLK1 is being removed and then try again. 2) HPOUT1 is not the headphones, but this is exceptionally unlikely but you could try the other HPOUT's just in case.
