How to set all volumes (media, ringer etc.) to some predefined value while booting?

[shridutt kothari]

I want to set all volumes (media, ringer etc.) to some predefined value while booting?

i have looking into it in AudioService class but not able to achieve it.

Any way to achieve it?

How about use alsa_amixer?

You may check the do_bootcomplete() function
of /etc/init.sh to understand how to do it.

First of all thanks Chih for your kind reply.

Yes before posting this, i did try the alsa command in init script, as per this thread,

I did put below code in end of the do_bootcomplete() function of /etc/init.sh

alsa_amixer -c set Master 100 unmute 

But this also didn't work and i don't understand why. So any alternate way to achieve it? What about using Java code in framework system service at boot time? any suggestion??

Thanks in advance!!

try to put it in a script, the ramdisk.img


extract :

zcat ramdisk.img | cpio -idmv


compress:

find . | cpio -H newc -o > ../ramdisk.img


insert command in script :

init.rc or init.android_x86.rc
