Help converting Sonic Unleashed Wii sound files DSP to WAV

[Sonicfans1]

So recently, I tried to rip the sound effects from the Wii version of Sonic Unleashed. I was able to get the DSP files, but when I put them in foobar2 using vgmstream, it doesn't want to convert for some reason. Using a basic txth file to brute force it only gave me a very ear-grating static noise. 

If anyone could help me troubleshoot this, I would be forever grateful

Niedawno próbowałem zgrać efekty dźwiękowe z wersji Sonic Unleashed na Wii. Udało mi się zdobyć pliki DSP, ale kiedy wrzuciłem je do foobar2 za pomocą vgmstream, program z jakiegoś powodu nie chciał się przekonwertować. Użycie prostego pliku TXTH do brutalnej konwersji spowodowało jedynie bardzo drażniący szum. 

Jeśli ktoś mógłby mi pomóc w rozwiązaniu tego problemu, byłbym dozgonnie wdzięczny.

Give a sample file.

It converts fine for me - if it plays ok in Foobar, then just right-click and select Convert.  Try updating vgmstream just in case you're using an older version.

Maybe I'm doing something wrong with my txth file? Converting it still gives me static. Without the TXTH File, it just gives me an error when I try to place the file in foobar

Here's my converted sound so you can hear my static mess, and my txth file, which "might" be the problem, as I have ZERO idea what im doing

 

As for VG stream, it's the most recent version (as I downloaded yesterday)

I should also mention that just putting it in foobar gives me the static sound

conversion is still static.7z .txth.7z

First of all, your txth file is completely wrong (i.e. it's not IMA, and it uses coefficients), but you don't need it for .dsp files.  Delete your .txth file and it should play in Foobar with vgmstream.

Ok, I’m at work rn, but I’ll try the when I get home 

 

I'm pretty sure I did it before without the txth file, and foobar gave me an error despite having vgstream downloaded though.

[Sonicfans1]

Ok, so deleting the TXTH file causes this error, which is how all this troubleshooting started. As you can see, I have the VGMstream plugin installed, but I'm getting this error message.

I even took the time to reextract the files from the ISO, and even that didn't change anything

Edit: Actually, only two files out of the sound folder actually worked, along with one file from the sound_stage11 folder, but none of the other files are working

UPDATE: 
Thanks to some help from a Discord server I was in, I finally got the sounds to play.
 

It required a txth file to work,but it did work

 

codec = NGC_DSP
channels = 1

start_offset = 0x60
num_samples = @0x00:BE
sample_rate = @0x08:BE

loop_flag = @0x0C:BE$2
loop_start_sample = @0x10:BE
loop_end_sample = @0x14:BE

coef_offset = 0x1C
coef_spacing = 0x20
coef_endianness = BE

hist_offset = 0x40
hist_spacing = 0x20
hist_endianness = BE
