20/03/08 4.12.06 – Stable release update

  • PS3 – Enable System::setDSPBufferSize for numbuffers only.

  • Fix getOpenState always returning FMOD_OPENSTATE_STREAMING after getSubSound
    was called and the subsound was not actually playing.

  • Proper fix for FMOD_CREATECOMPRESSEDSAMPLE based sounds gradually going
    virtual over time (issue was possibly ps3 only).
  • PS3 – fix chirp noise when sound ends.

  • Event API – Fixed network auditioning with FMOD_EVENT_INIT_DONTUSENAMES

  • Event API – Fixed 64-bit EventSystem::load failing with FMOD_ERR_MEMORY
  • FSBankEx – Fixed FSBs built from cache being slightly different to original

  • .FEV file format updated! FMOD Designer 4.13.06 requires FMOD version 4.13.06,
    4.12.06 or higher.

  • When using FMOD_CREATESOUNDEXINFO, specifying a suggestedsoundtype of
    FMOD_SOUND_TYPE_MPEG will now load any tag data which will also
    allow loading of MPEG files with more than 4k of tags at the file start.

Can you clarify the symptoms associated with this fix?

We found via some usage patterns that over 24-48 soak tests sounds would gradually dissapear until there was no sound left. It was caused by mpeg codecs gradually becoming ‘reserved’ due to a threading/dma conflict of flags, and we’re rewritten/simplified it in this version. The last version was an attempt to fix it that seemed to work – but just made it take longer to happen.

We’re running 4.08.08 and are seeing some issues on the 1-2 hour time scale of sounds becoming virtual. It appears casually that the number of available hardware channels just starts to drop (more and more sounds cut each other out) although I don’t think we’ve ever run it long enough for it to get to 0.

Do you feel that switching to 4.12 would help with this problem, or was this specific problem never observed in the short time scale I described. (It’s still possible that we have our own virtualization or priority problems, but less and less likely given some tests we’ve run)

The issue has been around forever really so yes upgrading would help.
