   To answer my own question, I got I2S output working by enqueueing the two buffers immediately after calling `i2s_open`, which causes `sample_buffer_ready_cb` to be called as expected.
   
   ```
   struct i2s_sample_buffer *buffer1 = &buffer_pool.buffers[0];
   buffer1->sample_count = buffer1->capacity;
   i2s_buffer_put(&i2s, buffer1);
   struct i2s_sample_buffer *buffer2 = &buffer_pool.buffers[1];
   buffer2->sample_count = buffer2->capacity;
   i2s_buffer_put(&i2s, buffer2);
   ```
