RME and other pro soundcard suppliers have software drivers that installs a mixer process. These cannot be uninstalled or removed (without having other problems). During playback, mixing is not needed but interferes with sound quality. RME's mixer process creates some 30-70 context switches per second!
To prevent this interference, suspend Mixer process on foobar startup and resume on exit. Here are updated .bat files that do this for RME based cards (see rem #2 of both .bat files). For other soundcards, replace HDSP32.EXE (configuration process) & HDSPMIX.EXE with correct soundcard mixer's process name. Test and confirm which version you prefer.
