This is a note to let you know that I've just added the patch titled ALSA: hda/hdmi: set default audio parameters for KAE silent-stream to the 6.0-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: alsa-hda-hdmi-set-default-audio-parameters-for-kae-s.patch and it can be found in the queue-6.0 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d692584e82dfaccf58ff4cee568f38a9892db9fd Author: Kai Vehmanen <kai.vehmanen@xxxxxxxxxxxxxxx> Date: Fri Dec 9 12:18:21 2022 +0200 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.
