Hi everyone. I am trying to make ALSA work on Cupcake for TI OMAP which has
the TWL4030 sound.
I tried to use the main branch alsa_sound and alsa-lib but keep getting an
error:
hardware/alsa_sound/AudioHardwareALSA.cpp: In function
'android::AudioHardwareInterface* createAudioHardware()':
hardware/alsa_sound/AudioHardwareALSA.cpp:66: error: cannot allocate an
object of abstract type 'android::AudioHardwareALSA'
hardware/alsa_sound/AudioHardwareALSA.h:246: note: because the following
virtual functions are pure within 'android::AudioHardwareALSA':
the function is:
extern int snd_pcm_null_open(snd_pcm_t **pcmp,
const char *name,
snd_pcm_stream_t stream,
int mode);
//
// Function for dlsym() to look up for creating a new
AudioHardwareInterface.
//
android::AudioHardwareInterface *createAudioHardware(void) {
return new android::AudioHardwareALSA();
}
If anyone managed to make ALSA work on OMAP for Cupcake please help out.
Any Git repository I can use would be appreciated.
I have all the permissions correct in the init.rc and /dev/snd is filled and
everything is loading fine in the Kernel:
ALSA device list:
#0: overo (twl4030)
So it's just Android.
Any help would be appreciated. The error I'm getting now from Android is
this:
