I own a samsung HW-J450 soundbar and wanted to connect it to my laptop. It worked fine for the first week or so, until I left the soundbar unplugged for a couple of days. I reconnected the same HDMI cable to my laptop, and changed the source to HDMI but I didn't hear anything coming from the soundbar. I made sure it was unmuted, and volume was maxed out. The screen of my laptop even flickered when I connected the cable to show that the soundbar was ready. I've tried everything from the windows troubleshooter, to reinstalling audio drivers, and using an entirely different HDMI cable. Bluetooth still works fine, but it comes with a very noticeable audio delay.
How do I fix this weird issue? Also, I would greatly appreciate if someone had a way to reduce the audio delay through bluetooth on the soundbar.
