My new Denon DVD-2900 arrived today and it seems fine except for one issue - there's no bass output from the analogue RCA jack. I've tried using it with a digital connection to the amp and everything is as it should be. But when feeding the analogue outputs from the player into the amp (a Denon AVC-A1) I get all the channels EXCEPT the LFE, both with the player's own test tones and source material. I've used a Millennium DTS decoder through those same inputs for a few years and I've confirmed that they're working fine. The problem seems to lie with the player - it's just not passing the sub channel out. I've also tried fiddling with the various speaker configurations but to no avail. Any ideas before I take it back as faulty?
