TVTime and no sound/sound


the sound is available if tvtime is selected then the external tv source is powered after a pause of about 10 seconds

if the external tv source is powered before tvtime is selected, the sound lasts for 2 seconds then mutes

this is repeatable

any ideas anyone why this happens? any proposed remedy?
(this is using analog tv card, external SatRx and pulseaudio)
