Configuring Audio Output Settings
After connecting Aspire iDea to your audio system, you can run Realtek HD Audio to set up and
adjust the audio.
1. Open Media Center.
2. Select More Programs > Realtek HD Audio.
3. Select Speaker configuration.
4. For analog audio output, select the option describing the number of speakers connected to your
system. For example, select 2 speakers if you have 2 speakers, 8 speakers if you have a 7.1
audio system and 6 speakers if you have a 5.1 audio system.
5. For digital audio output, the system default is to output audio source to both analog and digital.
No special setting is needed.
6. To setup special surround sound effect, with the Realtek HD Audio, you can use the Dolby Digital
Live or DTS connect to simulate 2-channel (stereo) sound into surround-sound effect.
T Select Dolby and enable Dolby Digital Live. Dolby Digital Live encodes audio signals
into a Dolby Digital 5.1 bitstream for multi-channel playback through surround sound
system.
T Select DTS and enable DTS Neo: PC or DTS interactive. DTS consists of DTS
interactive and Neo: PC, for both multi-channel and stereo content. DTS interactive
encodes audio signals into a DTS-compatible bitstream for multi-channel playback
through a surround sound system. Neo: PC transforms stereo content, such as MP3,
WMA, or CD audio, into 7.1-channel surround sound.
7. Press the OK button on the remote control or exit Media Center More Programs menu.
