Hi Team,

I am using CYW20719B2 in a custom board and trying to implement audio playback, I started the stream with audio data as sinewave, but I hear nothing from the earphones. I neither used AVRCP nor initialized it, should I use it to hear the audio ?

Regards,

Tamilarasan C

Issue: I had not initialized audio buffer while implementing my custom code. This doesn't affect other configuration/setup steps during implementation. It would be nice if there's snippets/templates for each profile, etc,.

Hi @TaC_4722371 ,

Yes you should be able to hear the audio without AVRCP profile. The CYW20719B2 should be acting as an A2DP source. 

Please check following example for audio implementation- https://github.com/cypresssemiconductorco/mtb-example-btsdk-audio-watch

Hi,

Thanks for the response. There's no need for volume related setup to be done to hear the audio?

No, you should be able to hear volume at a constant level.

1. How can I ensure that audio data (sinewave) is getting streamed ?

2. If audio is getting streamed successfully into peer device, but not heard in the peer device what should check in the code ?
