I've searched, but none of the sound problems I've seen match this in any way.
Okay, so here's the story. I bought this TiVo in 2003 (February) brand new. It's a Series 2
40 hour unit. (Old style front - Not silver like the newer ones. Not sure what revision, where can I find that?)
It's been like a godsend to me. I love it. But sadly, since September, it's been a hell of a burden. Moreso lately. Sound problems. But unlike anything I've seen on this forum or TiVo's support forums or anywhere.
There are two symptoms. Sound input recording and sound output to the TV. Here's what happens.
The first symptom is output. Usually this one occurs when you first turn on the TV. What happens is the sound will be non-existant. Except for a few scattered crackles. As time goes on I can hear words and parts of the audio. But mostly silence. Obviously the TiVo keeps playing even when I'm not home. But strange thing is it eventually goes away, er comes back. The audio that is. It comes back after the TV has been on for a while. Usually. Sometimes within minutes, sometimes a few hours. This isn't the big problem. It only happens sometimes. The real problem is the next one..
The second symptom and real problem and the reason I have almost smashed the thing open with a sledgehammer is recorded sound problems. Video is no problem. Video is never distorted. It's never broken. The audio on the other hand is crap. Basically what happens is one of a few things..
First is no sound at all. I can tell it's recorded sound because of course I still get TiVo sound effects. Just no audio in the recording. Since it's recorded to the video file, there is no way to recover it as the sound was never recorded right. So no waiting it out.
Second is sound will be there, but broken to all get out. With crackling here and there it's like I hear snippets of the program audio interspersed with crackling and silence.
Third is sound is there for the most part, but occasionally throughout the day's recording the problems comes and goes. I could be watching what seems to be a perfect recording when all of a sudden it starts. Crackle...... crackle.... crackle.. crackle. crackle crackle crackle silence............ No audio for minutes. None at all. Then like it went out, it comes back. Crackling and all. But when it's back the audio is horribly crackly. Sometimes loud cracks. Sometimes silent. Like right now, I'm watching a Seinfeld episode. It sounds fine.. but I can hear very silent white noise. Silent crackling. Nothing bad and this is the best I can hope for with this 2 year TiVo. But the episode of The Munsters I recorded yesterday has crackling all through it.
Sometimes it happens on all shows, sometimes only certain channels.
Now, I am not mad. Seeing as I've never seen this problem before, I am thinking it is a fluke. Just my rotten luck. I actually am looking forward to getting a new TiVo. Probably an 80 hour Series 2 Revision 4 (Current). But I hate to think I could have fixed this one myself. I'm not against just replacing this one. Especially since I was hoping to wait until a better TiVo (Series 3) came along.
Now, the problems started in September. When it started, I had just rearranged furniture. The TiVo was moved. BUT, I am so careful with anything with a HD in it, I doubt it was movement. (I've moved it many times before with no problems.)
Second, it's near the heater/AC vent. But I've felt the air behind the TV, there's no warmth. And it's not really that close. In fact, I can feel the fan of the TiVo blowing nice cool air. And the TiVo's internal thermometer says it's a normal 32║. Which sucks as overheating was my only hope. In fact, back in September, I managed to make the problem less by putting the TiVo on TOP of the TV. But of course, that isn't working anymore. Also, the vents are not blocked. Not at all. In fact, for the 1.75 years I had it before this, it was on a shelf with not 2 inches of space above it and lots of wires behind it. It had LESS air flow before the problem started getting really bad. (Could it be um.. underheating??)
What I've done already is I've moved it to get better airflow. I've checked all the cables leading to my TiVo. (My TV has the least amount of splits than any of the other dozen TV's in the house.) All are high quality. I've rebooted many times. It used to solve the problem temporarily, but now it doesn't do a thing except waste time.
I hate to have typed all of this out, but I just had to get this out. Hoping someone else was familiar with this problem.
It's only 2 years old. It would be nice if I could keep it and fix it. Even if I end up giving it to someone else as a "gift".
Any suggestions, ideas?
