PPCGeeks - WM6 CE OS 5.2.1620 (Build 18125.0.4.2) and in call volume

I've been reading about using audiopara.csv to increase in ear call volume but wondering whether it can be used on an apache with the above rom? In windows i couldn't see audiopara.csv. Looking to get something like an increase of around 15 to 20% from the current maximum volume. Noticed there was no audiopara.csv in the windows directory also.

any help much appreciated

cheers

p.s. before checking ppcgeeks, id never ever flashed a phone rom of any kind before and couldn't believe how easily it was! I installed the kitchen and was impressed with all the options available. Ive flashed my phone a few times now playing with the different options available and absolutely no problems! Big thanks to all the developers involved helmi c and luv2chill etc.
