[HELP] NO SOUND AT ALL! i9505/m919

I have been trying to fix this S4 (M919) which came without a T-Mobile rom (In Australia) and I have ran into audio problems over the past few days. I have attempted to fix it by recovering the modem but that did not help. I read about others fixing their phones with a simple flash but those i9505 firmwares do not work with this device. I flashed the T-Mobile firmware to see if it would work but still no sound (plus its not a T-Mobile SIM but that can be fixed by flashing CM12.1 :) )

It also says that in download mode it is a M919 but underneath the battery, it's a GT - I9505 O_o (what?)

I have tried flashing: modem_CWM_UVUAMDL, M919UVUFOH3, GSM_Modem_XXUFNA5 (FAIL), Albe95_S6_PORT_V4-5 (Same problem as other roms 'no sound' and BL_I9505XXUHOA7_user_low_ship_MULTI_CERTXX

Roms I tried: CM 12.1, CM 11, Slimrom Lollipop unofficial, Albe95_S6_PORT_V4-5 and some t-mobile based rom.

NOTE: I do not use T-Mobile, however t-mobile packages work but I still have 0 sound from speakers & ear piece.

Right now it is on CM 12.1 nightly build (jfltexx) + open gapps (Still no sound)

So can someone help me? Whenever I press volume controls, the phone would lockup (only on stock) and on other roms, there is also no sound (earpiece & speakers) also music players tend to crash (Such as AudioFX) . Please help me out! :(
