Patch for Dapper on Acer

Here is a patch for Ubuntu 6.06 kernel (2.6.15 with Ubuntu patches) that makes my soundcard work on my laptop. I own Acer TravelMate 4222 WLMi which have Intel HDA soundcard with Realtek 883 chip. ALSA driver for this card had a bug which was fixed this month in ALSA 1.0.13rc2.

I was not able to compile these new ALSA drivers for my distribution kernel (though for vanillas worked fine) and I need Ubuntu kernel because of its patches (like driver for my wifi). So i cooked up my own patch that applies to 2.6.15 ubuntu kernel (with alsa 1.0.10rc3).

Apply this patch to sound/pci/hda/patch_realtek.c of your kernel source.
