Note that the soundbar must be able to decode the bitstream signal in order to get proper sound pretty much all soundbars can decode basic Dolby Digital surround sound, but many can’t decode DTS surround sound or more immersive formats like Dolby Atmos and DTS:X. Some TVs and source devices have an “auto” option for digital audio output, which should be a safe bet. #Windows top left audio bar not present movieMany devices (especially TVs) default to converting all these signals to a two-channel PCM digital signal (the same as used for CD), which may cause the first few seconds of audio in a movie or TV program to cut out. The bitstream option, available in the audio setup menu of your TV and source devices (see photo below), sets the device to send the exact digital signal encoded in the program, be it Dolby Digital, DTS, Dolby Atmos, stereo audio, or the like.

You can always drag the icon out back onto the main section of the taskbar.
