Subject: sound7(): properly support channel flags on client; reassign sound flags so FORCELOOP... 
X-Git-Tag: xonotic-v0.7.0~32
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=59c97fef1d587930b89a05445af93db05aecb93c;p=xonotic%2Fdarkplaces.git

sound7(): properly support channel flags on client; reassign sound flags so FORCELOOP is now 2 (and FULLVOLUME is 16); note that these flags only work on csqc for now
