From c841ad2a9b86c7317dc7e4fe4e03bc56a6c0d6e8 Mon Sep 17 00:00:00 2001 From: David Henningsson Date: Mon, 19 Aug 2013 13:32:30 +0200 Subject: [PATCH] ALSA: hda - Try to allow haswell HDMI audio even without powerwell If compiled without CONFIG_SND_HDA_I915, the audio driver cannot request power well. However, if the power well is on for other reasons, maybe audio can still work. Therefore, do not skip the card completely if compiled without CONFIG_SND_HDA_I915.
