I am implementing AVS on ARM Cortex M4 based microcontroller. On my embedded platform, I barely manage to spare the resources required to play mp3 file. It will too much for my microcontroller if it had to support all the possible formats like mp4, vorbis etc. which are mentioned in Recommended Media Support.
At present, Alexa speech is always in mp3 format, and most of the music providers like TuneIN are also sending me mp3 only. But while playing the flash briefing, I once received mp4 content from NDTV news, and my device failed to play anything at all.
To avoid all such possible cases where my device might fail to play the audio, I want to make absolutely sure that Alexa never sends me anything other than mp3 audio.
Hence my question is: "Is there a way to request only mp3 audio from Alexa?"
