Hi Tis,
I am using DVRRDK4.0 and there is a AIC33 codec(hw:0,0) in my board
Something wrong when execute arecord & aplay :
# arecord -f CD -D hw:0,0 | aplay -f CD -D hw:0,0
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: main:696: audio open error: Invalid argument
But when I run again, everything will be ok....
# arecord -f CD -D hw:0,0 | aplay -f CD -D hw:0,0
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
So...error will come out after system booting(the first time), arecord & aplay play normally at second time.
I find the similar discussion about this issue:

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