Roadhog4 Timecode - how to?

Hi Guys
next day...next challenges :)

So i have an LTC Widget and downloaded a smpte-wav.file

www.felusch.com/blog/?tag=download-ltc-timecode-25fps-wav-file

1. in SETUP-NETWORK-TIMECODE Widgets my widget 1990 is selected.
when i hit the beacon tile than nothing happens to the widget.
When i hit the beacon tile in SETUP-CONTROL PANEL-SYSTEM INFO-TIMECODE WIDGET 1990 then i see the LEDs flashing on the widget.
Whats wrong with that?

2. I can't see any timecode-input while the smpte-file is playing out of a PC
How does it work?

thank you Guys
regards
Jayjay


edit on Nr2: i have to increase the volume then i see timecode coming in.
