I use gpio pin mux. # pcm hint.pcm.0.at="apb0" hint.pcm.0.maddr=0x180b0000 hint.pcm.0.msize=0x1000 hint.pcm.0.irq=7 # I2S hint.gpio.0.func.1.gpiofunc=15 hint.gpio.0.func.1.gpiomode=1 hint.gpio.0.func.2.gpiofunc=14 hint.gpio.0.func.2.gpiomode=1 hint.gpio.0.func.3.gpiofunc=13 hint.gpio.0.func.3.gpiomode=1 hint.gpio.0.func.4.gpiofunc=12 hint.gpio.0.func.4.gpiomode=1 Atheros I2S is very good. Becase of Ralink and almost other SOC's I2S don't have master clock. I checked atheros master clock by frequency counter. It's very stable. Almost high end audio. Hiroki Morihelp
