V.r 1.8

January 25, 2021
Prerequisite Upgrades

Windows Vista/XP support removed - This release does NOT support Windows Vista/XP due to the .Net Framework 4.8 upgrade. Windows 10/8/7 are supported. Matrix Mic V.r 1.7 will remain available for customers on Windows Vista/XP. Contact Support for information.
Prerequisite .Net Framework 4.8 Upgrade - This release upgrades to .Net Framework 4.8 which contains some .Net improvements (performance, high DPI display support, more) and bug fixes. This version of .Net should have been installed via Windows Update on most systems. If for some reason it was not installed, see this page for the .Net 4.8 download link (free).
NAudio V1.10 Library Upgrade - This Library is the primary code behind the Windows Audio driver. This upgrade includes performance improvements and bug fixes.

Output Groups and Devices Redesign

This is a recommended release upgrade for all customers.
Bug fixed - Output Groups were sometimes not playing audio to the expected target device(s). The Output Groups feature was redesigned to fix this issue.
Enhancement - The redesign now auto-detects when USB soundcards are added or removed (while Matrix Mic is running, no restart required). It also auto-detects when changes are made to the Windows audio subsystem (ex. Windows Default Playback Device changed, etc.)
Unfortunately migration of your old Output Groups is not possible due to new design controls. It requires a Reset of all Output Groups and Devices which will be done automatically when you install and run this release.
Recommend that users save a listing of their current Output Groups setup as a guide BEFORE installing this release. Click Tools > Outputs/Devices > View Output Groups and Devices.
Editing and setup of Output Groups remains basically the same. (Learn more )
Removed - Device Volume settings - This setting was redundant with the existing Windows Taskbar Speakers icon that allows you to set the Device Volume for individual devices. Simplifies Matrix Mic volume settings and operation.
Note - Importing Output Groups - DO NOT import any old, saved Output Groups. After the redesign, old Output Groups will likely produce errors.
