Cannot get I2S sample working

[Elppu]

Hi!

I cannot get I2S echo sample to work on nrf54L15. Tried following overlay

&pinctrl {
	i2s20_default: i2s20_default {
		group1 {
			psels = <NRF_PSEL(I2S_SDIN, 1, 14)>,
					<NRF_PSEL(I2S_LRCK_M, 2, 7)>,
					<NRF_PSEL(I2S_SCK_M, 2, 9)>;
		};
	};
};

i2s_rxtx: &i2s20 {
	status = "okay";
	pinctrl-0 = <&i2s20_default>;
	pinctrl-names = "default";
};

build configuration  nrf54l15pdk_nrf54l15_cpuapp

I verified with oscilloscope that no clock is modulated or wordselect switched. What might be the problem?

Is the i2s driver mature on nrf54 series / something new that has to be done?

I got this working using PORT_P1 and not PORT_P2  for i2s pins. Feature or bug?
