From 856282f166d7b95004e70859ca87cf33eb7f9a6d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Amadeusz=20S=C5=82awi=C5=84ski?= Date: Wed, 6 Jul 2022 14:02:28 +0200 Subject: [PATCH] ALSA: hda: Reset all SIE bits in INTCTL MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Old code resets SIE for up to 8 streams using byte accessor, but register is laid out in following way: 31 GIE 30 CIE 29:x Reserved x-1:0 SIE If there is more than 8 streams, some of them may and up with enabled interrupts. To fix this just clear whole INTCTL register when disabling interrupts.
