Hi,
'Side' is the subwoofer on my laptop (my laptop has an integrated subwoofer, believe it or not.
Hmm, then it's a wrong assignment. "Side" shouldn't be LFE.
Acer calls it "Tuba cinebass" or something like that). Apart from that, the PC has a headphones/SPDIF jack, so I believe it supports 7.1?
No, it's totally irrelevant. (SPDIF is 2-channel only, BTW. Multi-channel is done via compressed formats, but the physical channels are only two.)
