Pull request overview
This PR refactors the multiband_drc module to use the sink/source API exclusively, aligning it with the ongoing transition toward Pipeline 2.0.
Changes:
- Migrates Multiband DRC module processing from
audio_stream/buffer-position updates tosof_source/sof_sinkacquire+commit semantics. - Updates Multiband DRC processing function signatures to return status (
int) and propagate errors. - Adds small helper utilities for computing “samples until wrap” in circular buffers.
