I notice in "Volume mixer" volume bar for mozila (when i try listen to youtube) pops up and down but "Device speaker/headphone" on main system sound bar stays empty. Same for windows media player and everything. Thats with drivers from dell and drivers from autoupdate same issue.
Its a brand new PC !!!
