From d353eaa9a8133cdad8c1da23c84f9f529a23f0c2 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 10 Jan 2011 16:07:11 +0100 Subject: [PATCH] ALSA: virtuoso: configure correct master clock frequency on the CS2000 The clock output of the CS2000, which is used as master clock for the DACs, was using half the actual master clock frequency for some reason. Using the theoretically correct frequency seems also to work in practice.
