@ranj063 I can't figure out how instance numbers are handled/generated, if I used the array notation it seems the instance is a global value across all pipelines? That's not how IPC4 defines the instance number, is it? |
The widget should only be defined in the scope of a pipeline, otherwise the instance management is global instead of local to the pipeline. Signed-off-by: Pierre-Louis Bossart <[email protected]>
For some reason we had the EQIIR for topology1/IPC3 but we didn't add it for topology2/IPC4. All recordings show there's a strong DC offset with RT722 and other codecs, so let's add this component by default in the non-passthrough cases. The widget is added in the scope of a pipeline, so that the auto-generated instance is not handled at a global level. Signed-off-by: Pierre-Louis Bossart <[email protected]>

FIXME: the instance numbers for eqiir don't look quite right, for some reason we cannot use eqiir.41.0, as if the instance number was global and not in the scope of a pipeline?
