I'm not getting a subwoofer test tone to play from my new Sony SCD-CE775 SACD player through the 5.1 multi-channel input on my 950. I've verified that the player is producing the tone (by hooking the sub-amp directly to the player and hearing the tone), so I'm wondering if the ".1" analogue input on my 950 is "broken"?

Has anyone else has run into this?

Is it possible that the tone is being filtered out before making it to the sub-out on the 950? (When played directly through the sub-amp, the tone has a pretty high frequency for a subwoofer tone.)

Also, for the record, I've double-checked the cables involved, so the cables aren't the cause. And I have no problem getting the 950's built-in sub-tone to play, so that part of the 950 is ok as well. Thanks for your help.
