I have been using SheepShaver for years on Intel Macs. But this issue has appeared on my new M1 iMac, running macOS Monterey. It has continued over a couple months of use. I experienced the issue with an older build (which I had installed Nov 20, 2021) as well as with the latest build (version 2.5.2022.09.13). The sound issue may occur after running SheepShaver for less than 10 minutes, or after 30 minutes or 2 hours or more. Sometimes I have left SheepShaver running for hours in the background, in which case it may still be working when I return, but it is more likely that it will be frozen when I return, or will render graphics and cursor movements for a few seconds but then freeze as soon as I click. It's possible that a freeze may coincide with clicking on a button or performing another operation that would normally trigger a sound, based on the behaviour I have observed. One time, I went into the Sound control panel and confirmed that the sound had stopped for Mac OS 9 as well as the Mac OS 9 application I had been running. I did not notice the "flashing menu bar" effect that normally occurs in Mac OS Classic when the volume is muted. One time, when I selected a different "beep" sound, SheepShaver immediately froze. The applications I was running are a couple Mac OS 9 games (Imperialism and Heroes of Might and Magic III). After the sound issue, like I said, SheepShaver will appear to function normally for a while, though it seems to be more likely to crash imminently, even within 30 seconds, though sometimes it takes longer, and I am able to save files successfully. Thanks.
