SceAudioSRCChReserve is the first call to an estimated function. My guess is that it is the same for the other estimations. At least for sceAudioSRCChRelease it is because as a test I moved the call to that function early into the main() of PSPdisp and it freezes at that point.

I think it would work fine then like with sceKernelGetModuleIdByAddress. Once I added that to the launcher imports and it didn't have to be estimated by HBL it was possible to call that function without freezing. I am not keen on changing the launcher again to add more imports because doing that is a real ***** (you have to update the HBL SDK each time).
I will reiterate what I stated before: In my opinion the change in FW 6.60 is that only imported functions can be called with a syscall. All non-imported functions have a syscall assigned but calling it will cause a freeze. I don't think syscall estimation will be possible anymore.
But really that is no problem because we could just import every
export of a library and then have HBL determine the lowest syscall and the gap from these information. FROM_LOWEST syscall estimation can then be used so that the NID array doesn't get too large. Not a big deal, it just has to be implemented. Getting all library exports is easy too because you only have to use prxtool to generate stubs for a decrypted firmware module and then build that into the launcher (same way I did the current imports but I deleted all that were not known by name).
