Fixes #9983.
Add handling for errors that may occur during setup of an audio DMA player.
audio_dma_setup_playback()
callsaudio_dma_load_next_block()
to fill one or two buffers with audio source data. This PR adds preservation of the error indication in the newdma_result
field inaudio_dma_t
and examines it inaudio_dma_setup_playback()
. If an error indication is present, shuts down the player and throws an "Audio source error".For #9983, the error indication occurs frequently due to the MP3 decoder being unable to synchronize with the incoming MP3 stream. The app can now retry (sometimes a few times) to synchronize with the stream.
