First of all I´ve got to apologize for my bad english.

In this posting I wrote about my sound problems.

Switching to a german fta HD channel like ARD or ZDF leads to sound async.
Switching back to minimized playback syncs the sound. after starting fullscreen playback the sound stays in sync for 10-20 minutes, then again going async.

I´m using vdr-plugin-xvdr 0.9.9.-2 (VDR Server 1.7.42-2 etobi) and openelec clients with xvdr-addon Hardware ion2 board A/V via HDMI
