Hi All I am porting Android on ARM11 MPCore. Android is coming fine. Some issues are there in Audio playback.
When I play wav file using alsa_aplay, sound is coming. But when I play from Android audio player there is no sound. Following is the logs - I can see the "Unable to attach mixer to device AndroidOut: No such file or directory " how to solve this?? # logcat --------- beginning of /dev/log/main I/DEBUG ( 905): debuggerd: Sep 6 2010 18:29:30 I/Netd ( 904): Netd 1.0 starting --------- beginning of /dev/log/system I/Vold ( 903): Vold 2.1 (the revenge) firing up D/Vold ( 903): Volume sdcard state changing -1 (Initializing) -> 0 (No-Media) W/Vold ( 903): No UMS switch available D/AndroidRuntime( 907): D/AndroidRuntime( 907): >>>>>>>>>>>>>> AndroidRuntime START <<<<<<<<<<<<<< D/AndroidRuntime( 907): CheckJNI is ON I/ ( 908): ServiceManager: 0xacd0 E/ALSALib ( 908): external/alsa-lib/src/control/control.c:902: (snd_ctl_open_noupdate) Invalid CTL AndroidOut W/AudioHardwareALSA( 908): Unable to attach mixer to device AndroidOut: No such file or directory E/ALSALib ( 908): external/alsa-lib/src/control/control.c:902: (snd_ctl_open_noupdate) Invalid CTL AndroidIn W/AudioHardwareALSA( 908): Unable to attach mixer to device AndroidIn: No such file or directory I/CameraService( 908): CameraService started: pid=908 D/AudioHardwareALSA( 908): openOutputStream called for devices: 0x00000002 D/ALSAModule( 908): open called for devices 00000002 in mode 0...
