I think those are correct now. I have logged snd_pcm_hw_params_dump(params, log); snd_pcm_hw_params_dump(swparams, log); In salsa:- ACCESS: RW_INTERLEAVED FORMAT: S32_LE hebrew SUBFORMAT: STD SAMPLE_BITS: 32 FRAME_BITS: 320 CHANNELS: 10 RATE: 44100 PERIOD_TIME: (37142 37143) PERIOD_SIZE: 1638 PERIOD_BYTES: 65520 PERIODS: (4 5) BUFFER_TIME: (148594 148595) BUFFER_SIZE: 6553 BUFFER_BYTES: 262120 TICK_TIME: 1000 tstamp_mode: NONE period_step: 1 sleep_min: 0 avail_min: 1638 xfer_align: 1638 silence_threshold: 0 silence_size: 0 boundary: 1717829632 In alsa:- ACCESS: RW_INTERLEAVED FORMAT: S32_LE SUBFORMAT: STD SAMPLE_BITS: 32 FRAME_BITS: 320 CHANNELS: 10 RATE: 44100 PERIOD_TIME: (21333 21334) PERIOD_SIZE: (940 941) PERIOD_BYTES: (37600 37640) PERIODS: (5 7) BUFFER_TIME: (127981 127982) BUFFER_SIZE: 5644 BUFFER_BYTES: 225760 TICK_TIME: 0 start_mode: DATA xrun_mode: STOP tstamp_mode: NONE period_step: 1 sleep_min: 0 avail_min: 940 xfer_align: 940 silence_threshold: 0 silence_size: 0 boundary: 1479540736 Is there significance to 'hebrew' on the format line? The other numbers mean little to me. Sorry to trouble you.
