Task-free I2S speaker (audio sink) component for ESP-IDF v6.0.x, built on the modern i2s_std driver. Application calls a blocking i2s_spk_send_buffer() to hand off pre-filled audio buffers; there is no internal FreeRTOS task and no TX-side application callback — the blocking call's return is the sole completion signal.
