From a2cf96f929d54cb2c8041358053656bf76be2c34 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 15 Feb 2013 08:41:24 -0300 Subject: [PATCH] [media] au0828: fix audio input handling - V4L2_CAP_AUDIO was set, but enumaudio was not implemented. - audioset was never filled by enum_input - ctrl_ainput was never updated when switching the video input - g_audio was broken due to faulty logic: g_audio should set the index, it doesn't receive it from the user.
