So I've Installed Windows 10 from Windows 8 and have started to run into some issues regarding playing sound from my computer to my TV through HDMI. With Windows 8 it worked completely fine but ever since I upgraded when I go to lock my computer for the night or any other time during the day, when I decide to log back in sound no longer plays through my HDMI but still works fine through my speakers(headphones). Another thing I have noticed is that it also makes opening up the playback devices screen or changing to another device slow and lag a bit. Hopefully someone has some idea what it is if you need any more info about my system please let me know Thank you.
