I have a first generation Phillips TiVo box HDR312. Suddenly the only sound I'm getting from the TiVo box is static. If you crank the volume, you can hear sound mixed with the static but very faint. Picture still looks great, every thing else functions normally. When I bypass the TiVo (or put it on standby) and connect cable or DVD straight into the tv, I get perfect sound. I've tried it on two TV's. Weaknees suggested it might be the power source. Anyone know what else could be causing the loss of sound.
