To begin with I have tested the arecord command with these error messages… TEST 1 root@rockpi-s:~# arecord -f S16_LE -d 10 -r 16000 --device=“hw:0,0” test-mic.wav Recording WAVE ‘test-mic.wav’ : Signed 16 bit Little Endian, Rate 16000 Hz, Mono arecord: set_params:1358: Channels count non available TEST 2 root@rockpi-s:~# arecord -f S16_LE -c 2 -d 10 -r 16000 --device=“hw:0,0” test-mic.wav Recording WAVE ‘test-mic.wav’ : Signed 16 bit Little Endian, Rate 16000 Hz, Stereo arecord: set_params:1416: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 16000 PERIOD_TIME: 125000 PERIOD_SIZE: 2000 PERIOD_BYTES: 8000 PERIODS: 4 BUFFER_TIME: 500000 BUFFER_SIZE: 8000 BUFFER_BYTES: 32000 TICK_TIME: 0 Any suggestions?
