- s_scaleDownAndClamp CVar so the clamping and scaling down of all sounds (that is done to prevent clipping) can be disabled (enabled by default) - s_alOutputLimiter CVar to allow configuring ALC_SOFT_output_limiter which (if enabled) reduces the overall volume if it gets too loud, to avoid clipping (defaults to -1 = "let OpenAL decide") - s_alHRTF to allow enabling or disabling HRTF, requires ALC_SOFT_HRTF (defaults to -1 = "let OpenAL decide") Those CVars can be changed at runtime and are applied immediately (in case of s_alHRTF and s_alOutputLimiter by resetting the OpenAL device, just like we do when a disconnect is detected)
