I am experiencing a similar issue as the following:
However, my issue continues after I did a fresh install of Mojave (on a 2012 Mac Mini). I installed the OS, ran the High Sierra Direct Mode hack, installed a fresh version of AS, and played a track in AS. Worked fine for a bit, then…massive skipping and eventually…silence. The track continued to “play” but no audio could be heard. AS was also the only app I had running. CPU load started at about 50-70% and jumped to 100%). Also, when I quit AS and then restart (without playing music) the CPU load fluctuates between around 15% up to 48%. Since this first happened I have continued to try and successfully use AS to play music and every time…the same problem.
This happens: with Exclusive Mode on or off, with Integer Mode on or off, with Direct Mode on or off, SysOptomizer on or off. Mostly, it happens almost immediately, but sometimes it can take a while for things to go south (anywhere from right away to even up to four hours). Buffer is at 15360 MB (have tried the lower end of the spectrum and points in between and…no difference). No signal processing or upsampling.
My past setup (2010 Mini and High Sierra) worked fine and never skipped. The CPU load on that setup was very low (5%).
Not really sure what is going on, or why the CPU load is so high on the 2012 Mini with Mojave, but…sure would like to resolve the issue ASAP. Any thoughts, ideas, solutions would be most welcomed.
Thanks!
