This should be <1 2 3> and in DTSI: qcom,din-ports = <3>; The downstream waipio-audio-overlay.dtsi says: 56 qcom,swr-port-mapping = <1 SWRM_TX1_CH1 0x1>, 57 <1 SWRM_TX1_CH2 0x2>, 58 <1 SWRM_TX1_CH3 0x4>, <1 SWRM_TX1_CH4 0x8>, 59 <2 SWRM_TX2_CH1 0x1>, <2 SWRM_TX2_CH2 0x2>, 60 <2 SWRM_TX2_CH3 0x4>, <2 SWRM_TX2_CH4 0x8>, 61 <3 SWRM_TX3_CH1 0x1>, <3 SWRM_TX3_CH2 0x2>, 62 <3 SWRM_TX3_CH3 0x4>, <3 SWRM_TX3_CH4 0x8>; I just don't know what how to trim the port config properties - we have there four entries, but channels are only three? Where do these come from? The downstream: asoc/waipio-port-config.h / lahaina-port-config.h Do do not have port config for this SWR. Best regards, Krzysztof
