Subject: ALSA: hda - Add a PC-beep workaround for ASUS P5-V
X-Git-Tag: v2.6.35~9^2
X-Git-Url: https://bbs.cooldavid.org/git/?p=net-next-2.6.git;a=commitdiff_plain;h=dc1eae256cfac03bf17bf3eb016e3a6423d3f9d5

ALSA: hda - Add a PC-beep workaround for ASUS P5-V

ASUS P5-V provides a SSID that unexpectedly matches with the value
compilant with Realtek's specification.  Thus the driver interprets
it badly, resulting in non-working PC beep.

This patch adds a white-list for such a case; a white-list of known
devices with working PC beep.
