The ALSA problem troubled me for a few days, I found some infos from
here,and I modified BoardConfig.mk exactly as all guys said below
http://groups.google.com/group/android-porting/browse_thread/thread/ea411a5becb8aa3f/61334919dcaaeba5?lnk=gst&q=ALSA#61334919dcaaeba5
but ,the alsa still can't work . the alsa_amixer commed can be
executed well, I can saw the all mixer controls. the error occurred
while logcat be executing , the error log is below. I have no idea
which file is "Permission denied". I have changed authority to 777 of
all rootfs file befor copy to sd card.
The /proc/asound/cards info is as follow:
cat cards
0 [Interface ]: aaci-pl041 - ARM AC'97 Interface
ARM AC'97 Interface at 0x000000002002b000, irq 7
My sound card is WM9713
can any guys give me a hand? thanks...
