Hello, We tried to record and play the recorded file using arecord and aplay as follows: arecord -f cd /home/test.wav aplay -f cd /home/test.wav The file gets recorded and played correctly. But if I try to record file of format S8 or U8, I get error: # arecord -f U8 /home/test_alsa_record_2 Recording WAVE '/home/test_alsa_record_2' : Unsigned 8 bit, Rate 8000 Hz, Mono arecord: set_params:979: Sample format non available # arecord -f S8 /home/alsa_record_2 Recording WAVE '/home/alsa_record_2' : Signed 8 bit, Rate 8000 Hz, Mono arecord: set_params:979: Sample format non available Is there any other way to set the format as S8 or U8? Or only cd/cdr/dat formats can be played using alsa?
