From f1eaaeec11982c6b529d4255987fdf507a5fa69e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 13 Feb 2009 08:16:55 +0100 Subject: [PATCH] ALSA: hda - Allow fixed codec-probe mask Some devices have broken BIOS and they don't set the codec probe-bit properly after cleared by the driver. This makes the driver skipping the necessary codec slots. Since BIOS update isn't always easy, now the semantics of probe_mask option is changed a bit. When it contains the bit 8 (0x100), the lower bits are used to probe that slots regardless of codec-probe bits returned by the hardware. For example, probe_mask=0x103 will force to probe the codec slot #0 and #1.
