1. Depending on your sound card and/or number of speakers, choose the best suited Speaker Environment by clicking from the drop-down menu and making your selection.
   • Headphones is mainly for notebook users who listen to their audio output on headphones.

   • 2 Speaker is the selection for most users playing DVD on their desktop/laptop who only have 2 speakers or a sound card that only outputs two channels. This selection utilizes DirectSound, Microsoft's application programming interface (API) and makes up the wave-audio component of the DirectX® API.

   • The Use SPDIF 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/DTS decoder along with a SPDIF-compliant sound card to make this selection available.

Note: If the SPDIF audio output is enabled, the volume control for PowerDVD will be disabled as your decoder assumes the task.

• The 4 Speaker selection is for computers equipped with sound cards which support 4-ch output.

• The 6 Speaker selection (a.k.a. 5.1 channels) is for computers equipped with sound cards which 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.

2. The following selections will only be available depending on your selection in the Speaker Environment section.
   • 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. For more information, see Miscellaneous.

   • 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 (Optional).

   • The 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 well-damped Living Room, a small Theater, or a large Stadium. For more information, see CL Headphone.

Note: This option does not appear in all versions of PowerDVD.

• The Dolby Virtual Speaker option allows you to experience virtual surround sound through 2 speakers. For more information, see Dolby Virtual Speaker (Optional).

• CyberLink Virtual Speaker is a virtual surround technology developed by CyberLink. For more information, see CyberLink Virtual Speaker.

• CLMEI-2 (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. For more information, see CLMEI-2.
