Speaker environment

PowerDVD note Audio Settings

Note: these settings are disabled in versions of CyberLink PowerDVD that use Dolby PCEE to optimize sound for media playback.

Depending on your sound card and/or number of speakers, select the speaker environment that matches the number of speakers you have:

  • Headphone is mainly for notebook users who listen to their audio output on headphones.
  • 2 Speaker is the selection for most users playing discs on their desktop/laptop who only have 2 speakers or a sound card that only outputs two channels.
  • The 4 Speaker selection is for computers equipped with sound cards that support 4-ch output.
  • The 6 Speaker selection (a.k.a. 5.1 channels) is for computers equipped with sound cards that support 6-ch output and is optimal for DVD Video titles that feature multichannels encoding such as Dolby Digital 5.1 or DTS 5.1.
  • The 7 Speaker and 8 Speaker options are available for users who have multiple speakers and wish to output audio to each of them.
  • The Use S/PDIF option is an advanced technological Digital InterFace, as opposed to transferring signals via conventional analog interfaces, designed by the Sony and Philips corporations. To enjoy true 6 speaker output quality, you must have an external Dolby Digital or DTS decoder along with a S/PDIF-compliant sound card to make this selection available.

Note: when the S/PDIF audio output is enabled and the output stream is not PCM, the volume control for CyberLink PowerDVD is disabled because your decoder assumes the task.

  • The HDMI output selection is for users who have their audio connected with an HDMI (High-Definition Multimedia Interface) connector.

Note: the selections that are available in the Output mode drop down menu are dependent on the selection made in Speaker Environment and the configuration of your computer.

  • The major difference between Dolby Surround* Compatible Downmix and Stereo is that Dolby Surround uses the Dolby Surround downmixing algorithm and the possibility exists of connecting an analogue Pro Logic decoder to the sound card so as to enable 4-ch surround sound (left, right, center, surround) for Dolby Surround. Otherwise, both are relatively similar in 2-channel output.
  • Dolby Headphone* is a post-processing effect designed to create a virtual surround sound experience particularly for a headphone environment, but is suitable also for both notebook and desktop environments. For more information, see Dolby Headphone.
  • The TrueTheater Surround* (CyberLink Headphone) option uses technology developed by CyberLink to improve the quality of audio output from a notebook over headphones. The Advanced options simulate the very different experiences of listening to sound in a living room, a small theater or a large stadium. For more information, see TrueTheater Surround (Headphone Mode) – Optional.
  • The Dolby Virtual Speaker* option allows you to experience virtual surround sound through 2 speakers. For more information, see Dolby Virtual Speaker.
  • TrueTheater Surround* (CyberLink Virtual Speaker): is a virtual surround technology developed by CyberLink. For more information, see TrueTheater Surround (Virtual Speaker Mode) – Optional.
  • TrueTheater Surround* (CyberLink Multi-channel Environment Impression technology 2): is an audio channel expansion technology developed by CyberLink that converts a stereo audio sound and outputs to multiple channels (converts a 2 channel source to 4, 6, 7, or 8 speakers or a 6 channel source to 7 or 8 speakers). For more information, see TrueTheater Surround.
  • Dolby Pro Logic IIx*: has three options. For more information, see Dolby Pro Logic IIx (Optional).

S/PDIF Output Modes

The following output modes are available during the playback of Blu-ray Disc titles when S/PDIF is selected as the speaker environment. The mode that you should select depends on the external decoder (AV Receiver) connected to your computer.

  • Only primary audio: this mode only outputs the audio from the primary video (e.g. no sound will be available for Picture-in-Picture, secondary video streams or director commentaries). The compressed audio format is passed-through to the external decoder unit (AV Receiver).

Note: if the primary audio format is another format besides Dolby Digital, DD+, DTS or DTS-HD, CyberLink PowerDVD will decode it and output both audio signals simultaneously.

  • Dolby Digital* mixing: this mode outputs both primary video sound and secondary video sound simultaneously by mixing both audio and encodes into a Dolby Digital bitstream. Select this option if your external decoder unit (AV Receiver) supports Dolby Digital.
  • DTS* mixing: this mode outputs both primary video sound and secondary video sound simultaneously by mixing both audio and encodes into a DTS bitstream. Select this option if your external decoder unit (AV Receiver) supports DTS.

HDMI Output Modes

The following output modes are available when an external decoder (AV Receiver) is connected with an HDMI connector under Windows Vista. The mode that you should select depends on the external decoder (AV Receiver) connected to your computer.

  • PCM decoded by PowerDVD: this mode creates a digital representation of an analog signal. Select this option if your external decoder (AV receiver) does not support Dolby Digital or DTS to produce a digital sounding output for your audio.
  • Non-decoded Dolby Digital/DTS audio to external device: this mode passes compressed audio through to your external decoder (AV receiver). Select this option if your amplifier/receiver supports Dolby Digital or DTS to enable either during playback, when available.
  • Non-decoded high-definition audio to external device (HDMI 1.3 only): this mode passes lossless audio through to your external decoder (AV receiver). Select this option if your amplifier/receiver supports high definition audio to enable either during playback, when available.
