From aa9c293ae46d71f5add0761bce8db67b162e3f29 Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Wed, 21 Jan 2009 15:08:03 +0100 Subject: ALSA: do not create OPL3 timers if there is no OPL3 irq wired Most cards have OPL3 FM synthetiser but they do not have OPL3 interrupt wired to a sound chip or CPU. Do not create OPL3 timers for such cards as the timers are useless witthout interrupt. This patch removes OPL3 timers for following alsa drivers: snd-ad1816a, snd-opti93x, snd-opti92x, snd-sc6000, snd-cmi8330.
