From 5c0d7bc103dd1ae85967fbcf70be8d1ae3aa3d79 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Jun 2008 17:53:35 +0200 Subject: [PATCH] ALSA: hda - Fix bdl_pos_adj value for ATI SB chipsets ATI SB controllers seem to report the DMA ahead in the amount of FIFO. Thus bdl_pos_adj should be 32 for them as default. Also, the default value is set to -1, which means to make the driver to choose the appropriate value.
