Lately, there has been a lot of emphasis on reducing cold start latency
which audio hardware path setup takes up good chunk of time. I found
DAPM takes up quite a bit of time finding path to enable. In addition,
DPCM could be enhanced to save on cold start latency by enabling
front-end & back-end in parallel if underlying hardware can support it.

I would like to see if we can have some discussion on optimization.

Thanks
Patrick
