How can I reproduce this issue? Please help provide detail information
about your operation.
On my side, I just do:
--->8---
while true;
do
insmod snd-soc-atmel-pcm-dma.ko && insmod snd-soc-atmel_ssc_dai.ko &&
insmod snd-soc-wm8731.ko && insmod snd-soc-sam9x5-wm8731.ko;
amixer cset numid=14,iface=MIXER,name='Output Mixer HiFi Playback
Switch' on;
aplay sample.wav;
rmmod snd-soc-sam9x5-wm8731.ko && rmmod snd-soc-wm8731.ko && rmmod
snd-soc-atmel_ssc_dai.ko && rmmod snd-soc-atmel-pcm-dma.ko;
done
---8<---
It works well on my side on at91sam9g35ek board, based on v3.13-rc1
Best Regards,
Bo Shen
