StreamReader with frames_per_chunk less than a specific value gives partial audio signal when streaming

[lokesh_v]

When frames_per_chunk is given a value less than a specific value, Streaming the audio only gives partial audio. Here if the frames_per_chunk less than 2297, then streaming stops without fully streaming the audio.

Info

• Using sox_io as backend
• Audio file (https://dl.espressif.com/dl/audio/gs-16b-1c-44100hz.flac)
• torchaudio - 2.0.0+cu118

Using StreamReader with frames_per_chunk=sample rate

Using StreamReader with frames_per_chunk=1000

Changing buffer_chunk_size=-1 fixed this issue.
