:-) I meant the new TiBook :-) If the iBook2 has tumbler as well, then try rsync'ing today from Ben's tree. It has a functional tumbler driver that works quite well (I've been working on it so that Ben can concentrate on other things :-P). I'd be interested in hearing from iBook2 owners as to how well it works on their hardware. On my to-do list for the "Texas"/tumbler/TAS driver: * Enable DRC since the TiBook speakers are less than good * Enable control over input line 2 (is this connected?) * Play with the dual six-stage cascading biquad filtering to see how we can use it to our advantage (currently not implemented) * Fix balance control * Reorganise/rewrite most of the driver to make it easier to work with I have filter settings for the TiBook2's built-in speakers, but need to rewrite a large part of the driver anyway (otherwise, DRC usage won't be reflected in mixer sliders, etc), so I'm holding off on enabling the biquad filtering. Already working bits include: * Volume control consistant now * Added bass/treble adjustments * PCM level (for wav/CD playing) is adjustable seperately from master volume
