From: Kai Vehmanen Date: Fri, 9 Dec 2022 10:18:21 +0000 (+0200) Subject: ALSA: hda/hdmi: set default audio parameters for KAE silent-stream X-Git-Tag: v6.0.16~72 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d65f82a851c6003cb6735904ce763900faa2d678;p=thirdparty%2Fkernel%2Fstable.git 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.
