Dear Ti E2E Community,
I facing the below error, am using am335x & ti sdk 8
Something wrong when execute arecord & aplay :
arecord and aplay does not work for the first time & it works after throwing error after 5 times
Couple of times I get the below error:
root@lifeline:/# arecord -D VINL8 -f S16_LE | aplay -D VOUTR8

But there is no answer...
Could someone give me some clues?
