Do not ignore the fifo_size parameter in the st30p tx pipeline api (#948) #949

Closed hogliux closed 3 months ago

hogliux commented 3 months ago

The st30p pipeline API allows the user to specify the fifo_size parameter. Unfortunately, the parameter is ignored and not used anywhere in the codebase. This parameter is critical for achieving low latency audio streams.

See issue #948
