From: Peter Ujfalusi Date: Fri, 9 May 2025 08:59:51 +0000 (+0300) Subject: ASoC: SOF: ipc4-pcm: Delay reporting is only supported for playback direction X-Git-Tag: v6.14.9~53 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2db952eeaf63b7065928dbd23d62b7f8018b26d0;p=thirdparty%2Fkernel%2Fstable.git ASoC: SOF: ipc4-pcm: Delay reporting is only supported for playback direction commit 98db16f314b3a0d6e5acd94708ea69751436467f upstream. The firmware does not provide any information for capture streams via the shared pipeline registers. To avoid reporting invalid delay value for capture streams to user space we need to disable it.
