I have no sound effects with Dolby Digital Audio. How do I resolve this?
If your Series3 or Premiere series box is set up with a digital audio connection to your TV or A/V receiver (HDMI or optical cable), you will not hear TiVo sound effects while watching live TV or recorded programs that include a Dolby Digital audio track. With Premiere series boxes, you will also not hear TiVo sound effects while watching Live TV or a recorded program in the Video Window as you navigate through TiVo menus with HD if the program has a Dolby Digital audio track.
This is normal. The box automatically selects the Dolby Digital track, if present, to record the highest quality sound possible. To conserve memory and disk space, TiVo software does not include sound effects that are compatible with these tracks.
If you are viewing a program that does not include a Dolby Digital audio track, you will hear TiVo sound effects while navigating through the TiVo menus and screens.
