audio echo by using command line

[Matthias1912]

Hi

I’m new here and I have a question. I’m using the vlc player for watching analog TV. When I set the parameters by mouseclick in vlc, everything works fine. But when I set the parameters by command line, I have an audio echo.
Here my parameters from the batch file:
VLCPortable.exe dshow://
:dshow-vdev="MEDION (7134) WDM Video Capture"
:dshow-adev="C-Media Wave Device"
:dshow-size="320 x 240"
:dshow-fps=25
:no-dshow-config
:no-dshow-tuner
:dshow-tuner-channel=28
:dshow-tuner-country=49
:dshow-tuner-input=1
:dshow-video-input=0
:dshow-audio-input=3
:dshow-video-output=0
:dshow-audio-output=1
:video-on-top
:disable-screensaver
:quiet

Where I’m wrong. The audio echo is very annoying.
Thanks for help.

Can someone please help me.
I checked the option :no-audio, but I disable the wrong sound with this option. After using this option the echo is gone, but the sound is not synchronized with video anymore. The effect increases by using the additional command :dshow-caching=<int>

Please help me.
