It's better to add the following to system/core/init/devices.c :
{ "/dev/snd/", 0664, AID_SYSTEM, AID_AUDIO, 1 },But I haven't got my sound to work yet... I got myself an asound.conf with things as : pcm.AndroidPlayback_ etc... I get the following in logcat: D/AudioHardwareALSA( 2089): Mixer: element name: 'Master' D/AudioHardwareALSA( 2089): Mixer: element name: 'Front' D/AudioHardwareALSA( 2089): Mixer: element name: 'Front Mic' D/AudioHardwareALSA( 2089): Mixer: element name: 'Front Mic Boost' D/AudioHardwareALSA( 2089): Mixer: element name: 'Mic' D/AudioHardwareALSA( 2089): Mixer: element name: 'Mic Boost' D/AudioHardwareALSA( 2089): Mixer: master 'PCM' not found.
