Mockingboard sound is completely GONE

[ghedger]

The sound on the Apple II was not great; the Mockingboard made it marginally better and had its own charm. I did extensive work some time ago to perfect the Mockingboard emulation as I worked on the real thing back in the day, debugging timing issues on the looping circular buffers. Now the Mockingboard emulation is totally GONE.

Would you mind checking out older versions to find which commit broke it?

[ghedger]

Sure -- though looking at the log I have an idea. Might be a couple of days before I can get to it.

[ghedger]

Okay, found it.

1a5a1bd works
4dc7f6b fails

[ghedger]

I don't have time to investigate it right now but did find the commit that broke it.

[maxolasersquad]

Thank you for that. Looking at that changeset, it is not obvious to me why that would cause such a change.

[ghedger]

...which leads me to suspect it's something to do with the configuration settings, either the location/contents of the linapple.conf or something downstream of that. The change, if I'm not mistaken, was adding support for a clock.

[maxolasersquad]

Hmmm. Your config hunch sounds like the right direction. Yes, the commit adds hardware support for a prodos clock.

[ghedger]

I don't remember if there was any hardware contention between ProDOS clock and Mockingboard because I never had a ProDOS clock in my Apple IIe. I do know that the Mockingboard worked in the Apple IIGS which had the clock built in (sample implementation as ProDOS clock I do not know).
