@ Reaper5639:
Thanks for the reply and no, i'm not a noob. I know there are 2 versions, 1 for 2.3.X and 1 for 4.X.X. I also know about the drivers and yes, i've tried all of them. The only one that works is "Without VFP" which just doesn't make sense because X10 has a single-core with freq higher than 800MHz. I really don't convolver and surround+ to be disabled! I use a modified stock rom (FeraLab GB v28 ~Harmony~) and yes my phone is rooted.
i'm already using V4A FX v2.2.1.1 with "Without VFP" + V4A XHiFi v2.1.0.2 with "CortexAx with NEON"
. Don't know if it makes any sense or if it helps but i took libv4a_fx_gb_CortexA8.so from github and placed it in system/lib with root explorer. Don't know why but when i try to place it in system/lib/soundfx (where the driver is placed by the app itself) it doesn't work. So i installed the app with "Without VFP" and the app placed libv4a_fx_gb.so in system/lib/soundfx and after a reboot i placed libv4a_fx_gb_CortexA8.so in system/lib myself.
For now i am very happy with the sound quality of V4A but it's a very weird issue and i still would like to see it solved.
