Review BlueAnt Soundblade Review: Pretty and loud

"Cannot turn off voice prompts," well I'm out. I bought a soundbar from Walmart's Onn brand and I'm sick to death of its voice prompts every time I turn it on, or off, or max out the volume! On my next PC build, the speakers are going to be the first thing I source, and then build around that!
 
Maybe I just haven't messed with PC audio in too long (I play PC games on my living room TV, so they get the advantage of the 7.2.4 home theater setup), but the lack of optical input or HDMI passthrough feel weird to me.

Getting a soundbar only to degrade your sound quality by using Bluetooth seems counterintuitive, AUX is limited to stereo without an LFE channel, so I guess the main idea is to use USB, but I would much rather not use up a USB port for audio if I don't have to, and I can't really see a reason for why you would here. Or have motherboards stopped having optical output since I last bought one?
