From: Cezary Rojewski Date: Thu, 23 Oct 2025 09:23:46 +0000 (+0200) Subject: ASoC: Intel: avs: Unprepare a stream when XRUN occurs X-Git-Tag: v6.18-rc4~16^2^2~7^2~2 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=cfca1637bc2b6b1e4f191d2f0b25f12402fbbb26;p=thirdparty%2Flinux.git ASoC: Intel: avs: Unprepare a stream when XRUN occurs The pcm->prepare() function may be called multiple times in a row by the userspace, as mentioned in the documentation. The driver shall take that into account and prevent redundancy. However, the exact same function is called during XRUNs and in such case, the particular stream shall be reset and setup anew.
