From f12aa40c9d76af5add413731d30565327219c41f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 30 Sep 2005 16:56:59 +0200 Subject: [PATCH] [ALSA] emu10k1 - Fix loading of SBLive Game board EMU10K1/EMU10K2 driver Fixed the error at loading SBLive Game board (and possible other models). The PCI SSIDs of this board conflicts with SB Live 5.1 Platinum, which has no AC97 chip.
