Have connected an Apple TV to a Sanyo flat screen TV 32 Connection is via the HDMI cable. When in TV mode, sound out via the RCA video ports located at the rear of the TV works fine. However when mode is switched to HDMI sound is only from the TV speakers. Have tried to fix this via the TV menu to no avail. Note have been testing the sound out using surround speakers and also Headphones. Also form time to time when in HDMI mode the sound from the TV speakers stops. Sound can then be restored by changing the mode to TV and then back again to HDVI mode.
