The video was digitally ripped from a physical retail DVD.

Classic Bollywood films have an extreme dynamic range. The whispering romance in "Ye Kahan Aa Gaye Hum" might be very soft, while the dramatic orchestral stabs during a fight or a revelation are deafeningly loud. If you are watching Silsila on a laptop, tablet, or in a room with background noise, standard Dolby Digital 5.1 will force you to constantly reach for the volume knob.

Avoid files labeled "5.1" that are actually upmixed stereo. True Dolby Digital 5.1 for Silsila is rare; the DVDRip source from the early 2010s (often from Yash Raj Films' own DVD master) is the genuine article.
