Hi Luca, I have checked out alsa-lib, alsa_sound from android git, and it doesn't generates any file with the name asound.conf , it generates alsa.conf in system/usr/share/alsa.conf (I cross checked Android.mk file ) which I copied in system/etc with the name asound.conf. But the system is crashing with the same logs.
Hi Ravi, 1. Use, "alsa_amixer contents" to get the controls and their values alsa_mixer will not work as the system is not even getting UP bcoz of the crash. 2. Create asound.conf based on the above result 3. Put it in /system/etc/ folder in your Android-target and check. I already tried with that but the system is still geting crashed. Please find attached my alsa.conf file Thanks & Regards Nimit On Fri, Jun 5, 2009 at 8:56 AM, crazygenie <[email protected]> wrote: > > ALSA will NOT work unless you have a valid asound.conf customized for > your audio controls. > > 1.
