how is your Bose connected to it? With my samsung TV, I had to change my sound input in the TV settings to go through the soundbar rather than the tv speakers.
You won't notice a difference in sound too much unless you do audio/studio editing.
If you're not a audiophile, then don't waste your money on one.
You'll be fine using the stock audio connector
TBH I've always just shut my laptop (puts it into sleep "hibernation" for a couple years now, it still works fine.
I would shut it off occasionally (once a month) for an update or something.
