But there is also another problem. Until the last update of Windows 10 I have used successfully installed software HD VDeck for simultaneous audio playback through the headphones (front panel) and through the speakers (back panel). But after restoring from sleep mode, the headphones was not working. I'm still don't know why.  Perhaps this is due to the fact, that H55M-LE does not support the Windows 10 (when I used Windows 7 OS everything worked fine). Although as normal (before the sleep mode), the headphones and speakers worked OK at the same time, as they are set in the HD VDeck. After installing the latest updates for Win10, the HD VDeck software became inactive (almost useless in my case). So what do I need to do to continue playing the sound both through the speakers and through the headphones (before and after sleep mode)?
