A word of advice, make sure to turn off Accurate VBeam Emulation when using HLE audio. It doesn't seem to be very beneficial in this game with HLE audio, as I got audio blips as well; turning it off helped. When using LLE audio, Accurate VBeam Emulation seems to do alright however.
Also note that the latest stable version is 3.0 (not 3.0-XXX). The one you're using is an experimental GIT version; think bleeding edge. The next stable release will be 4.0, but the latest GIT releases will reflect a lot of the coming changes for that future release.
