Prior to this change, every stream start was subject to a 1 second delay to allow for the microphone circuitry to settle, even if a microphone is not being used. This blocking delay, as well as being pointless for non- capture applications, can be problematic for synchronous use-cases such as alsa_recover() in PipeWire. Add a dedicated widget to handle the microphone delay, and link it into the microphone routes. See: raspberrypi#7525 Signed-off-by: Phil Elwell <phil@raspberrypi.com>
