Hi!
I just wanted to tell that 2.2.9-ac1,2,3 breaks sound in quake, which
isn't very nice. :-)
There's a small klick twice a second depending on the
selected sound-frequency. So I had a look in the patches and found this
bit of code beeing resposible for the damage:

So, is it wright to shorten the adress-range by one or is quake(glquake)
misbehaving? :-)
