Date: Fri, 29 Oct 2004 11:47:09 +0200 From: Patrice Mandin Subject: Reworked audio drivers for Atari platform These are reworked audio drivers for the Atari platform. Previous drivers were missing some features: - Test external clock plugged to DSP port on Atari Falcon 030. - Ability to select internal or external clock. So now, I generate a list of frequencies available, with the master clock and predivisor to use. One big caveat to this: I do not have an external clock, so I hope it works.
