Pulse Audio Volume Reset Fix

On my notebook (Lenovo T510i) right channel audio does not work anymore with openSUSE. After hours of wading through websites I found a solution:

openSUSE 13.x

edit the file:

/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf

change this:

[Element Speaker]
switch = mute
volume = off

to this:

[Element Speaker]
switch = mute
volume = merge

openSUSE Leap 42.1

above setting is already done, along with a lot of other, similar settings. Didn't find the proper place to fix. But alternate solution still works:

amixer -c 0 -- sset Speaker playback 100%

Probably best to put that in /etc/init.d/boot.local or similar

No idea why this works, because if you look at the settings with "amixer -c 0" before, it looks exactly the same as afterwards:

Simple mixer control 'Speaker',0
  Capabilities: pvolume pswitch
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 74
  Mono:
  Front Left: Playback 74 [100%] [0.00dB] [on]
  Front Right: Playback 74 [100%] [0.00dB] [on]
