Greetings of the day !!

1. In command prompt using Tinyplay command we verified the module is working. default wm8960 module is taking and audio also playing.

2. we played through alarm default songs and also customize the alarm song and able to hear it from wm8960 audio module.

verified in logcat it using card 0.

05-10 11:49:47.396 361 3007 D audio_hw_primary: start_output_stream: pcm_open: out->device: 2, card: 0, pcm_device_id: 0, rate: 48000, channel: 2, f9

3. suppose we played the audio through any media player application/app, we can't hear any audio.

but in logcat it showing card 1.

05-10 09:44:07.112 364 1721 D audio_hw_primary: start_output_stream: pcm_open: out->device: 1024, card: 1, pcm_device_id: 0, rate: 48000, channel: 28

3.1 what changes required to play the audio through media player app?

3.2 audio_policy_configuration.xml any configuration changes are required?

some configuration added in this but its not working as we expected.

I attached the logs for audio played through music player and alarm apps with different sample rates.

Thanks,

supraja
