Thanks for the response. Actually voice prompt is available in sink application only right. The ultimate requirement i need was to play a specific file through a2dp. I am using source application to send audio through a2dp and there is no audio prompt in source application.
From connectStream documentation i found we can read from file using streamfilesource. But how the file is to be processed? How it needs to be connected to a sink ( for eg : Stereo out) . can you speak chinese 394645065 发表于 2021-6-2 15:20

I am sorry i dont know chinese. You can use browser to translate right? . I know what you want to do, but as we know, the source application can only encode the audio, and send it to the sink devices which can decoder it, so if you want to play the .wav file, i suggest you get this files from like SD card, and connect the source's aux L and aux R to the sd card output, so you can send the .wav file you want. terrysmt1984 发表于 2021-6-4 09:32

My requirement was to render a file similar to audio prompt working in sink app. So i converted .wav to .prm and .idx file and stored it to internal flash by copying it in image folder of application just like sink audio prompt works. I was able to read the file in VM using streamfilesource() but when i connect it to sink(stereo), no audio comes also no error or panic. 学习
