I made a small modification to Ron Fries' venerable TIA sound emulation code (TIASOUND), which is currently used it every Atari 2600/7800 emulator around (I think). This is just a notice in case someone's interested.

It originally supported sample rates up to 34,100 samples per second. I think most emulators set the sound card sample rate to match, so this is sufficient. For the MESS emulator, I wanted/needed to support sample rates higher than the TIA clock, especially 44,100. So, I added support for that in the same way it already supported lower rates.

This also fixes a bug which affects anyone who tries to use higher sample rates with the current library.

The source code will be part of the next MESS release - feel free to email me if someone needs it before that.
