It is not abuse; the support forum is for real support, not outdated hacks. We don't care if the audio stutters on your computer because you're not maintaining full speed. That is the correct emulation. If you want to use your old build, you are free too, but recommending it as a superior solution than using modern builds is not going to earn you any respect, especially in the support forums. If you want an argument as to why, think about this:
Other problems in the game have been fixed since then; if people use your suggestion and run into other problems, they're going to want solutions. We point them to recent builds, and they have crap computers that can't run full speed on latest builds. There is no good solution from going to older builds on a global scale. If it works for you, and you're willing to overlook other problems, good. We refuse to support older builds to prevent problems like this from spreading. Whether you know it or not, you're hurting dolphin and the community.
On top of this, there is a clear rule on the matter of old builds. https://forums.dolphin-emu.org/Announcement-global-forum-rules
That is why your thread was locked.
