From 2bd1d9eb1c27034a77c8e1887156da72d6160ae1 Mon Sep 17 00:00:00 2001 From: Vitaly Wool Date: Wed, 4 Mar 2009 08:27:52 -0300 Subject: V4L/DVB (10833): em28xx: enable Compro VideoMate ForYou sound Compro VideoMate uses an external audio DSP chip, controlled via tvaudio module (tda9874a). This patch improves em28xx infrastructure to support an external audio processor and fixes the Compro VideoMate entry to work with it.
