Hi All:
I port to alsa-sound alsa-lib on X86 system and I use alas_ctl produce
asound.conf to /system/etc/.
When I tried to play Music Player on Android system, time line of
music player isn't correct and it can't play audio.
How to fix it? Thank you..
I modified init.rc file and add following .
# change permissions for alsa nodes
symlink /dev/snd/pcmC0D0c /dev/pcmC0D0c
symlink /dev/snd/pcmC0D0p /dev/pcmC0D0p
symlink /dev/snd/controlC0 /dev/controlC0
symlink /dev/snd/timer /dev/timer
chmod 0777 /dev/pcmC0D0c
chmod 0777 /dev/pcmC0D0p
chmod 0777 /dev/controlC0
chmod 0777 /dev/timer
chmod 0666 /dev/binder
chmod 0666 /dev/ashmem
#following are new lines
chown root audio /dev/snd/controlC0
chown root audio /dev/snd/pcmC0D0c
chown root audio /dev/snd/pcmC0D0p
chown root audio /dev/snd/timer
Following Error log:
