There's still a "global disable", but it only affects SFX and MFX effects. EFX effects are "always on", even for RAW mode streams. Processing that previously went into an LFX should typically go into an SFX. Processing that previously went into a GFX should typically go into an MFX. Only certain specific kinds of processing should go into EFXs, such as encoding effects that talk to the Kernel Streaming pin factory in a compressed format, or speaker protection effects that are necessary to protect the hardware in the system from vibrations. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Tim Roberts Sent: Wednesday, March 26, 2014 1:40 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Effects APOs With GFX and LFX APOs, even if you didn't provide a property page, the APO could be bypassed using the "Enable Audio Enhancements" checkbox in the Microphone Properties dialog. I've now changed one of my LFX APOs into an EFX APO for Windows 8.1. It appears that the APO can no longer be controlled by the "Enable Audio Enhancements" checkbox -- the APO is always being called. Is that the expected behavior? Is there no longer a global "disable"? -- Tim Roberts, timr@xxxxxxxxx Providenza & Boekelheide, Inc. ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
