On a Microsoft Windows CE 5.0-based device, you run a kernel that supports Remote Desktop Protocol (RDP) and the Ensoniq Model Device Driver/Platform Dependent Driver (MDD/PDD) audio driver.
You enable the software mixer in the Platform.reg file.
You connect the Windows CE 5.0-based device to a Windows XP-based computer by using
RDP.
You play an MP3 file or a Microsoft Windows Media Audio (WMA) file by using Microsoft Windows Media
Player.
In this scenario, you cannot hear the MP3
file or the WMA file if the
volume on the Windows XP-based computer is lower
than 50 percent.
This problem occurs because the volume control of the software mixer in Window CE 5.0 is fixed from 0 to -100
decibels (dB).
This range
is too large for a usable volume range.
A supported software update is now available from Microsoft as Windows CE 5.0 Platform Builder Monthly Update (February 2008). You can confirm this by scrolling to the "File information" section of this article. The package file name contains the product version, date, Knowledge Base article number, and processor type.
