Release Notes:

New function added:
1. Removed XML and dtscs files and other configuration files that may be possibly customized frequently from INF file. The benifit of this is that any change to them will not break WHQL'ed driver any more, so save potential WHQL process time and have faster response. 


Bug fixed:
1. Per guides from DTS, if provide given 6ch noise pink sound, those DTS modes Movie/Music/Game can tell obvious effect difference. When provide the given 2ch noise pink sound, Stereo wide/front modes can tell obvious effect difference. But no effect difference with Movie/Music/Game modes if provided 2ch pink noise. And no effect difference with Stereo wide/front modes if provided 6ch pink noise. So if current effect is good enough to Turblebeach, it will up to TB further evaluation and potential tuning.

SW Package version: V1.0.3.4
Release Date: 2015-06-17

Cnxt USB driver version: V1.32.23.5

Applications included:
DTS APO DLL - V3.4.32.0
DTS HPX DLL - V3.4.32.0
Cnxt generic setup - V7.48.0.1
Cnxt HPX property page DLL -V1.0.3.4

Cnxt APO Configure Service - v1.0.1.0
UIU - V7.48.0.0
UCI - V7.93.0.0
TB SSH Lib: V1.0.4

Release Notes:

Overview:
1. The V1.0.3.4-20150617-Win81 SW package can support almost all functions in Win8.1 English system, except two known issues:
   1). Sound there is no difference between Movie/Music/Game/Stereo Wide modes. 
   2). In Win8.1 Chinese system, modes cannot be returned from DTS SDK and resulted in empty drop list. 

2. The V1.0.3.4-20150617-Win7 SW package can support almost all functions in Win7 system (both English and Chinese versions), except one known issue:
   1). Sound there is no difference between Movie/Music/Game/Stereo Wide modes. 

Reason for two different SW package for Win7 and Win8.1 seperated:
1. Existing DTS SDK has two different get_Opmode and set_mode API sets. One API set can work in Win7 and another one can work in Win8.1. There is no an unified API set that can work for both Win7 and Win8.1 systems. So we have to release two different SW packages for Win7 and Win8.1 seperatedly. 
 

New Functions added:
1. Added DTS TM label on property page. 

2. Removed 4ch for playback EP in driver INF.



Bug Fixed:
1. Updated to new DTS APO SW (V3.4.32.0) in the SW package, which fixed "DTS Default Stereo Wide" or "DTS Default Stereo Front" models cannot support 8ch audio sources in Win8.1 (English) system. 

2. With the latest TurtleBeach V1.0.4 SSH lib, SSH function was supported and verified in Win7/Win8.1 English/Chinese systems.

SW Package version: V1.0.3.3
Release Date: 2015-06-15

Cnxt USB driver version: V1.32.23.5

Applications included:
DTS APO DLL - V3.4.30.0
DTS HPX DLL - V3.4.30.0
Cnxt generic setup - V7.48.0.1

UIU - V7.48.0.0
UCI - V7.93.0.0

Release Notes:

New Functions added:
1. Added new dtscs and xml files in the SW package which can support 5 room models now. 



Bug Fixed:
1. Updated to new DTS APO SW (V3.4.30.0) in the SW package, which fixed crash issue and HPX enable ON/OFF out of control issue. 


Known issues:
1. In Win8.1 system, playing a 8ch audio source file with "DTS Default Stereo Wide" or "DTS Default Stereo Front" modes, there is no sound output, while Movie/Music/Game modes can play 8ch audio sources correctly always. Note: when playing 2/4/6ch audio sources, all can be played correctly with all existing 5 DTS modes. 
   Reproduce procedure:
  1). Playback a 8ch audio test file with WMP. 
  2). Open Target Speaker properties->"Turtle Beach Audio Settings", select those five modes in turn. 
  3). We can find that the top 3 Movie/Music/Game modes can output 8ch sound correctly with different effects, but when turn to "DTS Default Stereo Wide" or "DTS Default Stereo Front" modes, speaker is silent. 

2. In Win7 x64 system, only first mode "Movie H5.1/7.1" can output sound. When turn to other 4 modes, speaker is silent. This is different from Win8.1 test result. 

3. The DTS TM label is not supported.

However, Windows Media Player cannot negotiate with the DTS automatically to provide multi-channel audio streams to DTS APO, which always provide 2ch audio to DTS APO.  
5. To verify the multi-channel audio processing feature of DTS APO, please follow below procedure:
  1). Run debugview tool(which can be downloaded from this link: https://technet.microsoft.com/en-us/sysinternals/bb896647) with administrator privilege, Open "Capture" menu, enable "Capture Global Win32" sub menu. 
  2). Use TTplayer to playback a 5.1ch or 7.1ch audio file. 
  3). Check the debug info in debugview tool, there should be a line like this:
  "SRSTech UtilHPX.cpp(63): SRSTech HPX::Init SRSTech HPX::Init(): m_Channel=6, m_SampleRate=48000"
  4). If the "m_Channel" value was 6 or 8, it indicates the 5.1ch or 7.1ch audio stream were provided to the APO correctly. Otherwise, the value will be 2ch, to indicate only 2ch audio were provided to the APO for surround processing. 
6. With current license from DTS, there will be a short "Beep" sound periodically. This is due to it is a test license from DTS. There will no such "Beep" if install the SW with official DTS license. 
7. To turn on/off the DTS surround DSP processing, please goto the playback Endpoint property page and click the button "Surround ON/Off". 
8. Verified OS so far: Win8.1 x64, Win7 x86 and x64. 

To be implemented in coming releases:
1. Multi-languages support in property page. 
2. Turtle Beach Supper Human Hearing DSP processing & property page control. 
3. Wrapper APO for multi-channel support to all media player applications.
