From b75550e1bc6b3b2c80b628e68628fca015634071 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sat, 16 Apr 2005 15:24:31 -0700 Subject: [PATCH] pmac: sound support for latest laptops This patch hacks the current Alsa snd-powermac driver to add support for recent machine models with the tas3004 chip, that is basically new laptop models. The Mac Mini is _NOT_ yet supported by this patch (soon soon ...). The G5s (iMac or Desktop) will need the rewritten sound driver on which I'm working on (I _might_ get a hack for analog only on some G5s on the current driver, but no promise).
