From 5aba4f8ec72b2b880c694b5ce58e67be508f7b7a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 7 Jan 2008 15:16:37 +0100 Subject: [ALSA] hda-intel - Support multiple devices It turned out that there can be multiple HD-audio devices on a single machine (e.g. on-board audio and HDMI on graphic cards), so we need to support multiple devices with snd-hda-intel driver.
