Hi Mark I noticed if we have... 1) Sound Card used DPCM 2) It exchanges rate to 48kHz by using .be_hw_params_fixup() 3) Codec had symmetric_rate = 1 We will get below error. I didn't confirm, but maybe same things happen if it exchanged channels/sample_bits. # aplay 44100.wav # aplay 44100.wav => [kernel] be.ak4613-hifi: ASoC: unmatched rate symmetry: snd-soc-dummy-dai:44100 - soc_pcm_params_symmetry:48000 [kernel] be.ak4613-hifi: ASoC: hw_params BE failed -22 [kernel] fe.rsnd-dai.0: ASoC: hw_params BE failed -22 aplay: set_params:1407: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 44100 PERIOD_TIME: (23219 23220) PERIOD_SIZE: 1024 PERIOD_BYTES: 4096 PERIODS: 4 BUFFER_TIME: (92879 92880) BUFFER_SIZE: 4096 BUFFER_BYTES: 16384 TICK_TIME: 0 This patch-set solves this issue. patch 1) - 3) are just cleanup patches. 4) is fot this issue.
