Hi Mark/Takashi, We're using the Dummy DAI and dummy component for the nocodec mode in the SOF driver and we noticed that there are no DAPM power status updates for the widgets because there are no output/input widgets in the Dummy component. Adding these widgets in the dummy component wont help either because we explicitly skip adding widgets for the Dummy component in the core. But it would be very useful for us to debug PM issue if we could have the DAPM power updates for the widgets in topology. Reverting the change that implemented the check for skipping the dummy component probe (ASoC: core: Don't probe the component which is dummy) would not be advisable because it will be used by multiple cards and will lead to the same issue again. More details about the issue can be found here: https://github.com/thesofproject/linux/issues/1987 What would your recommendation be to get around this problem in SOF? Thanks for your help. Thanks, Ranjani
