connect sound bar to laptop through HDMI

[JimJohn713]

i have a sony sound bar that im trying to use as my primary audio out from my laptop, problem is when i connect it to my laptop via hdmi it detects the sound bar as a second monitor and screws up my resolution. now if i turn off second display my audio goes with it as well, which is quite frustrating. My question is, is there any way i can just use the audio from my second display (sony sound bar) but not the display?
Im using a dell laptop with windows 10 and the sound bar is a sony SA-WCT100

stop using the HDMI cable and just use a 3.5mm to RCA cable.
