From b4e2a16f992288f1c5cddda1948c53ba3dde9cb3 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Mon, 16 Jul 2012 08:30:18 +0200 Subject: [PATCH] ALSA: wss_lib: Fix resume on Yamaha OPL3-SAx Yamaha OPL3-SAx chips don't resume properly when playback is running - garbage is played after resume. Restoring the CS4231_PLAYBK_FORMAT register last fixes the problem.
