Very strange behaviour. I attempted to replay a show recorded last night and there was no sound - also I noticed that the normal tivo sound effects for the UI didnt sound correct (but they were working).

I rebooted tivo and it came up OK, but still no sound from live tv source. Sound did work (albeit a bit distorted) during the startup animation.

Plugging the STB directly into the receiver excluded it as a possible source of the problem. Just to be sure I swapped tivos audio cables as well but it made no difference.

Going back to a recording made a few days ago tivo had sound working OK.

Today tivo has no sound output at all. Not even the sound effects from the UI. I have rebooted tivo several times and still no sound. Powering off makes no difference either.

Does anyone have a suggestion - or are my worst fears likely to be realised that it is a hardware problem and I need to replace/repair my tivo?

BTW my tivo is a Phillips US model HDR112 with a 160Gb hard drive and a Turbonet Cache card with 512Mb.

Thanks in advance for your help.

Peter.
