Hey, 2 of the biggest problems people are having with the current 1.04 is both the sounds in general not being the same as CS 1.6 sounds, and secondly the difficulty in hearing footsteps.
Now what im about to say of course isnt a fix that will solve all those problems - far from it, but it will definitely HELP.
I'll use dust2 as an example, but it applies to the other 3 maps aswell:
On CSP dust2, there are a total of 3 different footstep sounds found throughout the map. 1 - the soft crunchy sand noise that is found on the majority of the map, 2 - the louder 'default' footstep noise (concrete1-4.wav in the css GCF) found at the A bombsite and stairs for example, and 3 - the metal sound found on the top of a couple of boxes.
Compare this to CS 1.6, where over the ENTIRE map there is only 1 single footstep sound used - the 'default' footstep noise (pl_step1-4.wav in the cs 1.6 GCF).
The 2 sounds (pl_step1-4.wav, and concrete1-4.wav) are identical in both 1.6 & CSS (bar tad higher quality). With the number of people complaining about the sounds not being the same as CS 1.6, i cant understand why one of the ONLY few sounds that are in BOTH GCF's (1.6 & CSS) isnt used as MUCH as possible (or atleast, in every single place the sound is used in the 1.6 equivalents on the CSP maps) in CSP. Add to that, this default footstep noise is significantly louder and easier to hear and distinguish from the soft, crunchy sand noise used on the CSP dust2, which will help people be able to hear it better (gun sounds are still too loud, but it will help like i said at the start).
There are a number of other places where this default footstep sound should be used in the other 3 CSP maps but isnt, aswell as a number of questionable sound choices for other surfaces used (looking through the GCF's for both games there are better choice for some surfaces imo, although none perfect). In general, (as shown by the example of dust2 which only has 1 single footstep sound on the entire map in CS 1.6), there seem to be far more varying surfaces in the CSP maps which leads to numerous different footstep sounds, as opposed to in CS 1.6 where there are very very few variations. I think this should be looked at and fixed, starting most obviously with dust2.
