Hi. So I was building a cheap PC for brother with used parts, initially the sound worked fine(Windows 10), however he prefers Windows 7(God knows why) so I installed that OS instead. However now the sound is very quiet. I've tried everything I can think of to fix it. Audio drivers from motherboard site, played with sound settings, bios settings. I've even gone back to Windows 10 and it's still very very quiet. Can barely make out whats being played. Any suggestions?? Maybe realtek site would be better for drivers? I have no idea.
