I'm hearing from someone who ought to know that LFX APOs have been "deprecated" in Windows 8.1, now replaced by SFX, MFX, and EFX (stream, mode, and endpoint effects) APOs. There are no hits for those terms in MSDN. Is this true? Is there any documentation? -- 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/
