From 1bc9eed379399484d3f5d5a0834674983969bc1e Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Mon, 7 Jan 2008 12:24:45 +0100 Subject: [ALSA] es18xx: Enable wavetable input from ESS chips This patch enables wavetable chips ES689/ES69X connected to ESS ES18xx chips. The wavetable chip uses FM DAC if the clock signal from the wavetable is active. It has no effect if there is no ESS wavetable chip present.
