AUDSRV from cdrom problem.

[OzzyyzzO]

Hello,

I'm working on a homebrew which will boot as an iso.

Using SifLoadModule(..) i'm unable to load properly the AUDSRV.IRX (which is located into the CD root directory.

i've tried many combinations ->

SifLoadModule("cdrom0:/AUDSRV.IRX"
SifLoadModule("cdrom0:AUDSRV.IRX"
SifLoadModule("cdrom0:\AUDSRV.IRX"
SifLoadModule("cdrom:AUDSRV.IRX"

etc..

Please note that the elf and other data files are opened and read properly.
moreover i have only seen examples using host:audsrv .. any limitation?

thx for any help / hint

Hi
Just use these functions before loading irx from cd:

sbv_patch_enable_lmb();
sbv_patch_disable_prefix_check();

from sbv_patches.h and add -lpatches to makefile

No.

Functions:

sbv_patch_enable_lmb() <- Enables "LoadModuleBuffer()" on the RPC server
sbv_patch_disable_prefix_check() <- Disables the check that prevents the loading of IRX modules from certain locations (E.g. a Memory Card).

Loading modules from rom0: and cdrom: should work without any patches.

Did you load LIBSD before use? It seems like FREESD might not work.... so you might want to try to load rom0:LIBSD instead if your console has it (Only the SCPH-10000 and SCPH-15000 consoles lack this).
I don't know much about AUDSRV because I haven't really worked with it a lot.

It should be like this:

SifLoadModule("cdrom0:AUDSRV.IRX;1", <argc and argv>);

Please take note that the path is case sensitive.

What's the return value of SifLoadModule()?
Did you reset the IOP before loading any modules?

I need audsrv or freesd to initialise ps2 mikmod driver from evilo.

Here are the modules that are successfully opened at the very begining of my prg:

SifInitRpc(0);

SifLoadModule("rom0:SIO2MAN", 0, NULL);
SifLoadModule("rom0:PADMAN", 0, NULL);

later from the spu init of the mikmod driver:

static int spu2_init()
{
int error;

#ifdef USE_FREESD
// load freesd (libsd replacement)
error = SifLoadModule("cdrom0:FREESD.IRX", 0, NULL);
if (error < 0){
printf("libmikmod: Failed to open FREESD module %d,error");
return -1;
}
#else
error = SifLoadModule("rom0:LIBSD", 0, NULL);
if (error < 0)
{
printf("libmikmod: Failed to open LIBSD module");
return -1;
}


//sbv_patch_enable_lmb();
//sbv_patch_disable_prefix_check();

error = SifLoadModule("cdrom0:AUDSRV.IRX", 0, NULL);
if (error < 0){
printf("libmikmod: Failed to open AUDSRV module err:%d",error);
return -1;
}

// init audsrv
audsrv_init();
#endif

return 0;
}

;--------------------
The results:

sbv_patch functions doesn't help.
irx loaded from rom0 are sucessfully opened, in case we are using audsrv, rom0:LIBSD can be opened properly.


every other irx located into the CD root directoy (as is) are returning error: -203. (FREESD.IRX, AUDSRV.IRX)

Of course, i 've again tried other combinations like cdrom0:AUDSRV.IRX;1 or whatever i get the same error. I must be missing something really silly somewhere..?

You might want to reset the IOP, and initialize the SIF services properly before loading any modules by using something like these lines:

SifIopReset(NULL, 0);
while(!SifIopSync()){};

SifInitRpc(0);
SifInitIopHeap();
SifLoadFileInit();
fioInit(); /* Only needed if you use fio*() functions. */

every other irx located into the CD root directoy (as is) are returning error: -203. (FREESD.IRX, AUDSRV.IRX)

That's the SCE error code for "File not found".

Of course, i 've again tried other combinations like cdrom0:AUDSRV.IRX;1 or whatever i get the same error. I must be missing something really silly somewhere..?

You could access other files on the disc right?
I know that you've already tried several variations of the file name, but have you tried this: "cdrom0:\\AUDSRV.IRX;1"?

The double backslashes once tricked me too (The backslash character in C is an escape character).

audsrv: greetings from version 0.90 !

Thank you very much guys!

Thus the trick was the double \\ as SifLoadModule("cdrom0:\\AUDSRV.IRX", 0, NULL); is just working fine.

Even if it wasn't helpful in my case I'll keep the IOP & SIF services reset sequence but hey, it's completely voodoo to me ^^
