Dolby is a format which can be either 2.0 or 5.1 or 7.1 and Normally LPCM which is uncompressed audio signal is rated to be below Dolby and DTS format. For normal systems like sound bars or HTIB a good 5.1 or 7.1 LPCM recording will be good and you won’t find much difference

Do you have the link to the product? I’ll check specs and clarify.

Ok it supports 5.1 Dolby format and 2.0 in LPCM. So you don’t have to think to much and confuse your self. If the content you play has LPCM 5.1 recording it should most probably downstream and play it in 2.0 format. DD it will support 5.1

It only reads LPCM 2.0 & Dolby Digital 5.1 via optical or HDMI ARC
It cant read other formats LPM 5.1 / 7.1, DTS and HD codecs

If it’s Dolby digital all channels should work

Some sound bars have a small display which will show the output signal. Also you should be having some decoders that lets you upstream 2.0 to 5.1. I just checked YouTube and there are many unboxing and review videos available. I will recommend you watching them to get a live user experience on all scenarios

In sound bar go to menu > aud (audio) > strm (stream) >

There it shows LPCM or DOLBY DIGITAL. Please check
