I ask because I havent stopped searching the code to find out what's wrong with the audio.

I found one major issue in I2S_PowerOnInit, I think connected with Scu_ClockEnable function.

Here is the code from the compiled SDK:

ROM:60009AD0 I2S_PowerOnInit                         ; CODE XREF: Audio_Init+8p
ROM:60009AD0                                         ; UHInitialiseFirst+18p
ROM:60009AD0                 STMFD   SP!, {R4,LR}
ROM:60009AD4                 MOV     R4, R0
ROM:60009AD8                 LDR     R0, =0x1801C018
ROM:60009ADC                 LDR     R1, [R0]
ROM:60009AE0                 MOV     R2, #0x10000
ROM:60009AE4                 BIC     R1, R1, R2
ROM:60009AE8                 STR     R1, [R0]
ROM:60009AEC                 LDR     R1, [R0]
ROM:60009AF0                 MOV     R2, #0x20000
ROM:60009AF4                 BIC     R1, R1, R2
ROM:60009AF8                 STR     R1, [R0]
ROM:60009AFC                 MOV     R0, #0x64
ROM:60009B00
ROM:60009B00 loc_60009B00                            ; CODE XREF: I2S_PowerOnInit+34j
ROM:60009B00                 SUBS    R0, R0, #1
ROM:60009B04                 BNE     loc_60009B00
ROM:60009B08                 MOV     R0, #0xF
ROM:60009B0C                 BL      Intr_Disable

The function Scu_ClockEnable is an inline type, so no redirection in the code is performed.
But in the FW with well working audio it look like this:

ROM:60009858 I2S_PowerOnInit                         ; CODE XREF: Audio_Init+8p
ROM:60009858                                         ; UHInitialiseFirst+2Cp
ROM:60009858                 STMFD   SP!, {R4,LR}
ROM:6000985C                 MOV     R4, R0
ROM:60009860                 MOV     R0, #0x10
ROM:60009864                 BL      _I2S_EnableClock
ROM:60009868                 MOV     R0, #0x11
ROM:6000986C                 BL      _I2S_EnableClock
ROM:60009870                 MOV     R0, #0x64
ROM:60009874
ROM:60009874 loc_60009874                            ; CODE XREF: I2S_PowerOnInit+20j
ROM:60009874                 SUBS    R0, R0, #1
ROM:60009878                 BNE     loc_60009874
ROM:6000987C                 MOV     R0, #0xF
ROM:60009880                 BL      Intr_Disable

there is this function introduced _I2S_EnableClock (my name). The function doesn't exist in SDK at all. This is its code:

ROM:600E28BC _I2S_EnableClock                        ; CODE XREF: sub_600022B8+2Cp
ROM:600E28BC                                         ; sub_600029F0+3Cp ...
ROM:600E28BC                 LDR     R3, =0x1801C000
ROM:600E28C0                 LDR     R1, [R3,#0x18]
ROM:600E28C4                 MOV     R2, #1
ROM:600E28C8                 BIC     R0, R1, R2,LSL R0
ROM:600E28CC                 STR     R0, [R3,#0x18]
ROM:600E28D0                 BX      LR
ROM:600E28D0 ; End of function _I2S_EnableClock

if someone know how to translate it to C or how to put this code in *.s file to add it to ADS I would be glad. Perhaps this is the reason.
