coyo_geezerye esea didnt have STV+ or w/e so the damage number data etc. isnt recorded.
My Season 29 demos have hitsounds and damage numbers. Albeit, they only show up after the week 1 demos, but anything after that works.

I downloaded this demo in question and damage numbers/hitsounds work fine on my end.
These are the CE settings I use when looking at STVs.
ce_localplayer_enabled 1
ce_localplayer_player 1
ce_localplayer_track_spec_target 1
ce_antifreeze_enabled 1
ce_killstreaks_enabled 1
ce_hitevents_enabled 1
ce_hitevents_dmgnumbers_los 1
Also make sure tf_dingalingaling is set to 1 if you haven't done that already.
