hi! Pisound is not plugged. I’m testing my board without a hat, just probing pins. Can it be a problem of?:
arecord -D hw:pisound -c 2 -r 48000 -f S16_LE
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
RIFF$?WAVEfmt ???data?arecord: pcm_read:2145: read error: Input/output error
P.S I ve hardcoded pisound board serial and etc reading, so that driver could recognize it
Yes, without the board attached, the I²S won’t sync, as Pisound is the clock and frame provider.

But pcm1804 adc, and pcm5102 dac, which are used in pisound need no other pins, just i2s pins for work. Why can’t I just connect pcm1804 with i2s pins, and use pisound driver for record ?
I²S I/O won’t work without the I²S, OSR and RESET pins properly connected.
