I’m not really sure why this is happening, but if i activate Windows sonic while playing hots the sound gets really low volume and quality. Even with max volume in hots and system it sounds really bad. The problem goes away/comes back as soon as you change settings from Off to Windows sonic. I’m using Win 10 on a Lenovo B50-80 laptop with cheap Sony in-ear heaphones, i’ve never had this problem before and i first noticed it about 2 weeks ago.
EDIT: If anyone comes across a similar problem check in : Sounds,playback,your speaker,spatial sound -> here uncheck the turn on 7.1 spatial sound
