Csgo Footstep Sounds Bug Is Happening Again

in csgo, a footstep sounds bug has dogged many players. footstep sounds are not networked to your client if the enemy is dormant. this basically means that you won't hear footsteps if they are behind an impenetrable wall.

ever notice how footstep sounds aren't as reliable as they used to be? a while back, valve implemented a bandwidth optimization in which the server does not network players that aren't in your pvs (potentially visible set). there are times when you should be able to hear an enemy's footsteps, but since the player is dormant, you will not hear them.

here is a video showing the problem:

local player footsteps are muted for this video.

this is bad for competitive gameplay where hearing footsteps is crucial.
let's see what did other players say on the reddit post:
@iffoh:

i am fairly certain after testing a few maps that it effects you less then you think.
nuke ramp room is just a very special in that it is very noticeable there while on other maps not so much.
at least the few spots i tried
train at ivy it doesnt happen
cache b (and t infront of b running towards the site) doesnt happen
dust2 short stairs with bot at catwalk mid does happen but not as severe as on the ramp example.
edit: inferno me top banana bot at speedway and it doesnt happen
nuke ramp it happens but oddly enough the players wont be dormant when he jumps so you can hear him jumping even when you cant hear him run lol
edit2: what i did to test.
1. offline server with 1 bot (bot_stop 1; bot_dont_shoot 1; sv_cheats 1)
2. to see if the bot is dormant use r_drawothermodels 2 (not 100% sure if that is reliable or accurate tho but it somewhat lines up with the nuke findings)
3. put volume to max (rip ears) if needed use stopsound in console to stop ambient noise
4. put the bot in a location you want to test (bot_place)
5. go in the spot you want to test from
6. put in bot_mimic -1 and start moving around (you will be stuck into place for the test to move again bot_mimic 0)
7. if you don't hear steps def. make sure that the bot doesn't get stuck somewhere

@peekthunder:
since we're on the topic of footsteps, i'm going to mention this.....
setting up an example, let's say we're on the map mirage and the last man alive is in palace and you are pushing t ramp to flank him. in order to speed things up, you might let go of shift for half a second and then hold shift again so that you don't make any sound but walk faster. however, i'm pretty certain that the enemy will be able to hear footsteps the second you let go of shift, for each and every time you do that.
basically on your screen you don't make any sound but on his screen he will hear footsteps. the inconsistency is not good.

@sbod_:
is this why i can't hear people spawn anymore in the fragshack servers?
@kinsi55
when compiling a map, vvis builds a pvs (potentially visible set) as well as a pas (potentially audible set). probably the latter in combinition with the former has to do with this bug, hence why it works when you force-transmit players.

of course, some people are surprised:

there are people who feel this is not a bug:
 
as we know, the csgo footstep sounds bug has been appeared for a long time, but still haven't gotten fixed. so players are doubting this is a real bug or just a original design of the game. how do you think?
