Couple of things that I've found will muck up your sound: o ACPI, as you mentioned. Be glad that you can even get your system to boot with ACPI. Mine crashes within 10 seconds of hitting Enter at the boot menu. o Threading libraries. games/doomlegacy exhibits behaviour endemic of a sound buffering / channel issue (sound stuttering and playing slowly during periods of high activity, working better during periods of less activity) for me when it runs with libpthread. I spent *hours* (okay, I'm a Doom addict, I'll admit it) trying to diagnose the problem in the mindset that it was a buffering / channel problem, when all I had to do was set it to use libc_r in libmap.conf.

Unix is user friendly. However, it isn't idiot friendly.
