MicSelect=1 ; 1=Microphone #1 (Default) ; 2=Microphone #2 LineMap=1 ; 1=CD (default) ; 2=Video ; 3=Aux ; 4=Line ; 5=Reserved ; 6=Reserved ; 7=Phone ; Output mutes: ; These values can be set to force a given output path ; to be muted, always. ; Note: AltOut is normally connected to headphone jack. AltOutMute=0 ; 0=Audible(Default), 1=Mute MonoOutMute=0 ; 0=Audible(Default), 1=Mute ; Set default volumes for 3 mixer "master" volumes. ; These settings are usually overridden by MMPM/2 master volume application. MasterVolume = 50 ; Master volume default (0..100, default 50) AltVolume = 50 ; Headphone volume default MonoOutVolume = 50 ; Mono out volume default ; Set default volume for various mixer inputs. ; These settings effect what you "hear", not what you record. ; ; For example, adjusting "CDVolume" will change the listening volume ; of the CD-ROM playback signal. ; It will not effect the loudness of the signal recorded when an ; application records from CD. ; To effect recording level, use "ADCGain" and "ADCGainSkew" MonoInVolume = 50 ; Range 0..100 PhoneVolume = 50 MicVolume = 0 ; Default mic muted. Change to 50 to enable karoke. ; Note: This setting does not effect Mic record. ; Setting this value too high will produce a ; feedback loop. LineVolume = 75 ; Range 0..100 CDVolume = 75 VideoVolume = 50 AuxVolume = 50 ; Default record settings. ; These settings are normally overwritten by MMPM/2 APIs. ADCGain = 50 ; Default record gain MuxSelect = 1 ; Default record source (Use values from LineMap) MicBoost = 0 ; Default setting for +20dB microphone boost ; Microphone volume during monitor is managed separately from non-monitor. ; The microphone input is normally muted, but needs to be un-muted ; during monitor. For this reason, there are separate entries for ; microphone volume during idle time ("karoke", normally muted) and ; microphone volume at record preparation time ("monitor", normally audible). ; ; This loudness of the the microphone during "monitor" does not effect ; the loudness of recorded signal. It effects only the loudness of "monitor". ; To effect recorded microphone signal level, use "gain" setting from ; application. After exhausing application options (including gain and boost), ; the ADCGainSkew setting in this file can be used to effect a global change ; to recored volume. MicVolumeMon = 50 ; Mic volume during monitor. Range 0..100, default 50. ;---------------------------------------------------------------------- ; LOGICAL to PHYSICAL VOLUME TABLES ; ; Master volume tables (64 entries in each table). ; ; Each entry is a BYTE: ; D7 D6 D5 D4 D3 D2 D1 D0 ; 0 0 MR5 MR4 MR3 MR2 MR1 MR0 ; ; MR5..MR0 range 0..63 (decimal) which corresponds to ; audio range of 0dB thru -94.5dB in -1.5dB steps. ; 0x3F => Most quiet (-94.5dB) ; 0x00 => Most loud (0dB) ; ; Note: While titled as volume tables, the tables are more accurately ; described as attenuation tables as signals can only be made quieter.

WaveSkewPercent = 66 ; 100 means no adjustment. 66 means 34% quieter.Download Driver Pack
