Takashi,
When I run following commands with 2 pins inputs.
$ arecord -f S16_LE -r 48000 -c 4 -D plughw:0,1 --separate-channels c1.wav c2.wav c3.wav c4.wav
hd c3.wav and c4.wav returns 0 but c1.wav and c2.wav got right data. Such as $ hd c3.wav 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 005ad000
Also, I see trigger Rx start command and then stop command immediately.
Any hint to look into?
Thanks.
