hi,
 
Audio card (wm8776) cannot work in full duplex, CPU is FSL=20 P1022.
The PCB design about audio card reference FSL P1022 development board= , and=20 palying or recording is OK separately.
 
My question is whether P1022 audio driver cannot support full duplex?=
 
The following is my test method.
test script:

#!/bin/sh

echo=20 "start plarying"  
aplay /nor-disk/audiosrv/Success.wa= v=20 &
sleep 1

echo=20 "start recording" 
arecord -d 5 -t wav -D "plug:SLAVE=3D'hw:0,1'" = -r 19886=20 test.wav

 
when start "record", "aplay" just suspend, and I cannot listen voice.= when=20 record is over, I found aplay still suspend.
according to "ps -aux":

root=20 1499 0.2 0.1 4012 1500 pts/0 S 08:25 0:00 aplay=20 /nor-disk/audiosrv/Success.wav

 
But, I run this script in a PC linux, I can listen the voice, th= e=20 audio card can record my voice simultaneous.
 
Looking forward your response!
 
Thanks!

The P1022RDK was not a board that my team was responsible for, so I only did minimal work on it. I added support for it in the upstream kernel. It was so long ago that I don't really remember much about it. I still have the board, though.

Hi Timur=

thanks for your repons.

I have another question. Did you test full duplex in P1022 RDK board?
Our design is same with P1022 RDK.
