Audio Driver Issues Please Help

So my gaming laptop is relatively old (specs below) and lately I've been having audio issues on some games where I get no audio at all or audio just in cutscenes (audio outside of games is fine). My laptop uses Realtek HD Audio Driver as its main, and I've tried reinstalling it and its only a temporary fix that lasts about a day before it breaks again. So my question is how do I fix this/any better audio driver or is it just time for a new laptop? Keep in mind I'm not the best with computer terminology.
