Very happy with this purchase. I don't do gaming and just needed a fast reliable PC for surfing, apps and archiving with the ability to add in a Sata hard drive from my old PC which was super easy after finding a youtube video.  The onboard sound card (with only 3 inputs)  does support 5.1 multi channel sound. It didn't initially work, but was functional after I uninstalled and reinstalled drivers and found help on the Web (although the problem may have been pilot error with driver settings to enable 5.1).  Win 10 is super fast (compared to WIn 7 running on my old HP Envy). All in all this PC  is exactly what I wanted for performance and expandability.  It met and exceeded expectations.
