If the LG TV has an HDMI output with ARC (Audio Return Channel), this will certainly work. It is also possible to connect the soundbar via WiFi. The rear speakers will certainly work if the soundbar receives a signal.
I would have recommended the following product to you: Hama Speaker Stand - 1 Pair (Stand)
However, according to the following discussion and the subsequent review, this is probably not such a great combo:

PS: Possibly continue the discussion there and ask if you have found something suitable in the meantime (possibly outside Digitec).
Hello, the LED refers to the boxes that have a status LED, which is mostly blue. The indicator on the Soundbar should always be active and light up as soon as a change is made via the remote control or the Multiroom App. After that, it should go out again after a certain time. If necessary, try the software update via the Multiroom to remove a possible bug.
Hello, I also bought this soundbar and everything worked wonderfully. When setting up the soundbar, you also have to pair the remote control, with the up and down buttons as THkarrer wrote earlier. Did the remote control work during this step?
