From b0148a98ec5151fec82064d95f11eb9efbc628ea Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 18 Dec 2006 13:20:06 +0100 Subject: [PATCH] [ALSA] snd-aoa: fix onyx resume When the machine resumes the onyx codec might be in a weird state. Hence, simply fully reset it once (and keep the code to take it out of suspend in case the suspend of the codec chip survives a reset).
