h4. C.3 Sound configuration
----
To have the best audio feedback on your interface you should configure your audio inputs properly. First of all, go to the Sound Manager (speaker icon on the top right corner of the desktop)

*Headphones output*
Regulate this slide bar to a comfortable sound level.

*Pulse input ( Line in):*
_If you are using the Hauppauge card please skip this section_
First of all, go to the Sound Manager (speaker icon on the top right corner of the desktop), select the input you are using and set the values to 100% volume, no amplification.
Select the input you are using and set the values to 100% volume, no amplification.
Later, if you have distortion on your audio input, edit the conf.ini and set _amplification = 1.0_ in the AudioSource device.

*Headphones output*
Regulate this slide bar to a comfortable sound level.
_Recommendation_
----
On the pulse track of your conf.ini, don't leave the value _location_ as _default. List the inputs and set it. This way you won't need to check it every time you switch on your unit. To do that, run in a shell:

{code:none}
pactl list | grep Source -A 2
{code}

Identify the input you want to use, for example
{code:none}
alsa_input.pci-0000_00_1b.0.analog-stereo
{code}

Use the _name_ as _location_ on the _conf.ini_ pulse track
{code:none}
[track3]
name = AudioSource
device = pulse
flavor = presenter
active = True
*location = alsa_input.pci-0000_00_1b.0.analog-stereo*
file = sound.mp3
amplification = 2.0
vumeter = True
player = True
{code}
----
\\

*Galicaster Vumeter*
Add this section in the _conf.ini_ file.

If the NO SOUND dialog is coming in and out constantly, set a higher value on _min_, for example -40.
\\

* Alsa Advanced configuration *

If you still experience problems after configuring the Sound Manager and your Mixer or Sound input device, you should take a look to ALSA.
Run _alsamixer_ on a shell and ensure that your device is not being amplified.
