Hi, with SOF topology2 for IPC4, widgets might have mutliple queues they can be connected. The queues to use between components are descibed in the topology file. This series adds widget queue support (specify which pin to connect) for ipc4-topology with topology2. Note: currently queue 0 of a widget is used as hardwired default.
