ALSA: hda/hdmi: set default audio parameters for KAE silent-stream
[ Upstream commit b17e7ea041d8b565063632501ca4597afd105102 ]
If the stream-id is zero, the keep-alive (KAE) will only ensure clock is
generated, but no audio samples are sent over display link. This happens
before first real audio stream is played out to a newly connected
receiver.
Reuse the code in silent_stream_enable() to set up stream parameters
to sane defaults values, also when using the newer keep-alive flow.
