flashing not solved the problem..

[Khaba]

correct, i specifically:

before flashing, my mobile was an R4EA031 RED49 unlocked, unbranded, english phone. I flashing phone to solve the walkman player problem and to insert italian language. So, i flashing the phone with these firmware:

MAIN: W810_R4EA031_MAIN_GENERIC_RED_49
FS: W810_R4ED001_FS_EUROPE_5_RED_49
Custom pack: W810_CDA102555_14_R2A_Generic_EUROPE_5_RED_49

..Ok, mobile work fine and i have italian language now, BUT i have always the same walkman player problem described in my beginning post.

can anyone suggest a solution ? Only myself have this problem ?

you used the right fw version, don't worry about that. try to change the acoustics drivers, maybe it will help. I don't know what might be the problem. Good luck!
