I have a Premiere XL connected to an older Sony rear projection TV (KDS 60A2000) via HDMI which has worked pretty well.
I just purchased a Zvox sound bar for my TV. My Sony TV won't pass through the digital sound from my Tivo (a design limitation of the TV), so I have connected my Tivo directly to my new soundbar via a Toslink optical cable.
Usually it works fine. But sometimes I lose the sound. After a while - many minutes - it usually comes back. Troubleshooting is difficult since the problem is intermittent, but it seems to be an issue with the Tivo's toslink output, that does not affect the HDMI audio signal.
Anyone know of unresolved problems with the toslink output of a Tivo Premiere? What would the recommended audio setting on the tivo - Dolby or PCM audio?
