I reported this issue a year ago. I've seen others complain about this issue, too, but I do understand that it only affects some hardware systems (mine included, unfortunately). This occures from 4 different scenarios; (1) after opening any project, the first time I play a multitrack, the audio (all tracks) will cut-out after about 7 seconds. It looks like audio should still be generated (levels are bouncing around) but there is only silence. If I stop playback and re-start playback it continues playing as expected without the interruption (except for the other scenarios) (2) After a few hours of use, audio will cut-out. Again, it looks like audio should be coming out (levels are bouncing around) but no audio. In this case, the only recourse is to re-start Audition. (3) if looping playback, audio will cut-out after some number of loops. The tighter the loop, the faster the cut-out will occur. For instance, if I'm looping over 2 seconds, I can expect to get about 10-20 loops before the audio cuts out. The recourse is to stop and start playback again. (4) THIS IS THE WORST ONE: Any attempt to use prerendering on tracks causes that tracks audio (only that tracks audio) to cut-out after about 7 seconds. This means that I can't leverage prerendering at all which means I have to be stingy about the number of tracks I can use otherwise playback maynot be able to keep up (max ~ 20 tracks).
I've read previous threads about this issue (particularly about the prerendering piece). The BIOS on my beefy 2022 Alienware computer has the latest updates. My OS is on a fast SSD and I've tried setting Preferences->Media & Disk Cache->Audition Audio Disk Cache->Primary Temp to a 2nd SSD. These have had no positive affect.
