I purchase a new 15-dy1043dx. I connected the HDMI to my Onkyo surround system and set all to never turn off when the lid is closed so I use my 52" TV and system for the laptop. I set it to mirror the display. I leave the laptop on always but when I turn off the surround sound or switch to another input on the surround sound the laptop blips and makes sounds as if it is searching of finding new devices. Not the sounds when I connect a USB device but blips and bloops (sorry, that is the best that I can describe the sounds). I have turned off all APP and system sounds. I previously had an older laptop model 15-BA079DX attached in this way and it made no sounds?
