Today's Mini vMac Development source snapshot has a few more tweaks to sound for Macintosh II emulation. It now clears the FIFO buffer when changing the enable mode to FIFO, or when changing mono/stereo mode when in FIFO mode. In addition, one ReportAbnormal message is now suppressed, about a word sized write to VIA1 that occurs on shutdown in System 6.

There is a new Mini vMac Development source snapshot, with much improved sound in the Macintosh II emulation. It is not perfect, but good enough that sound is now enabled by default for Macintosh II in the build system. Variations 5358 and 5359 on the Latest Variations page have this Macintosh II emulation for Intel OS X and Windows. Calls to “ReportAbnormal” are now strewn throughout the code emulating the Apple Sound Chip, so it will tend to give warnings when ever it strays from states that have been tested.
Besides lots of experimentation and debugging, the asc.cpp source file of the MESS emulator was helpful. MESS has lately been merged with MAME, and now under GPL and BSD licenses.
There is also news about new software hosted at the site, but I'll let everyone click through to find that on their own.

As of August 28:
Mini vMac 3.4.1 is out of beta! I presume that means the 3.5 branch has now moved from alpha to beta.
This means that the stable Mac II build with audio is now in the official release stream (although the Plus is still the default download).
Also, there's now a port for the 3DS, ImportFL has been upgraded with bugfixes, Paul released some of his MPW tools for public use, and SDL2 builds in the development branch are improved (especially on OS X).
