That is not the real problem, major audio apps like Cubendo are aware of HT and “disable its use” or probably rather make sure that any cores they utilise are real ones, it is apps and even drivers that pre-date HT or are not aware of the problem that are presented with the HT “tread” as a real processor core (should not happen with drivers, all drivers should operate on the first core only, but some offload some tasks to user space and use threaded libraries, old sampler card drivers come to mind)
