I don't see anything unusual with regard to video artifacts.

At least one version of this problem is heat (too cold) related I'm positive of that. My Series 2 box has had issues for a couple years now. I didn't realize at the time it was just during the winter. Lately during the cool nights, it's been happening again, blocking the fan in the back has prevented it from happening.

Try it, let me know if it helps...

Well, mine is cold related, I'm sure of it. This past time, to confirm, I checked the temps, it was < 39C and making the noises. Took about 15 minutes or so and eventually it started working again. I quickly checked the temps and it was at 39C.

I haven't had the problem since blocking off the fan, but I check the temps often and they have been in the 45C range.

I'm guessing it could be a connection that's loose too, if it gets too cold or hot the connection breaks, or something like that. I just know when it's colder out or cold in the house, I have trouble. I haven't purposely cooled the machine to see if I can force it to happen. I can say that a reboot doesn't help, it needs to "warm up" for the sound problem to go away.

You're talking about mechanical noises, though, right? My noises are definitely electronic, not mechanical.

No, it's electronic. It's tough to describe, but it seems to alternate on about a 1 or 2 second intervals between silence and then screeching/crackling. It's not always the same screeching noise, sometimes lower tones, sometimes higher. The break between the silence and noise is pretty abrupt.

Around the time it's going to come back to normal sound, I can hear some of the sound effects from Tivo along with the noise. I'm often clicking through the menus trying to find the system temp, so I can sometimes hear the Tivo select, etc along with the screeching, etc.

Okay, but that's not the kazoo sound. I'll try what you suggest, if I can figure out how, but I suspect that we have different problems.

Correct, I don't think this is the kazoo audio, but more the "intermittent squealy audio... All I did was tape a piece of paper over the fan port. I didn't cover it completely, but about 80% of it is now covered.

I can confirm I had the same symptoms as Kirky99. They only manifested late and night through around 11:30 AM, but went away over the summer months. I had hoped they were gone, but came back a week ago (frost warnings, etc. started up here in Ohio). I tried tried all types of configurations with DVD, VCR, Cable Box (timewarner>pioneer) and Tivo Series 2 and it only showed up when the Tivo was in the picture. Changed out coax for component cables and still no difference. Called Tivo support and they had me walk through everything I had already done earlier that morning. Of course, while on hold at 11:30 while they were trying to figure out what else to try, the symptoms went away just on schedule. They told me since there wasn't any problem right now ,there wasn't anything they could do.

The next morning, the problem was back. I remembered reading this thread so, on a lark, I put my hand behind the fan, covering about 80%. Within about 30 seconds, I had sound back! A small piece of duct tape applied and I'm still problem free several days later. I keep checking the unit temperature and it's staying in the low-to-mid 40's, so all seems ok there.

THANKS, KIRKY99! You saved a great deal of frustration!

kirky,

I think I'm having the same problem as you (Series2, non-DT). I just moved this box to a new TV and now for some reason the audio cuts in and out, but if you leave the TV on for 20 minutes or so the audio starts playing clearly again. (It seems to just be the TiVo output - after it's warmed-up even the old recordings play fine). It's already "warmed-up" now, so I'll try your tape trick in the morning to see if it works.

Thanks for the insight

It's baaack!

Wow. I haven't heard the "kazoo" sound on my TiVo for quite some time, but it reappeared last night. I had recorded the Tonight show, and it was there for about 1/2 hour during the show.

Coincidentally, the first time I recall having the kazoo sound was on the season finale of the first "American Idol" series. Just recently, I recorded the season finale episode of "American Idol Rewind" (I haven't watched it yet to see if it also had the kazoo sound ).

I have 8.3.

I found that the kazoo sound often recurs just after we dust the living room.

Well, no dusting going on here in the past week! The problem has continued to occur a few times for the past few days. It was occurring just a few moments ago. I was about to reboot, but it stopped.

Annoying. The TiVo temperature is showing 47c, not great, but not bad.

My Tivo S2 will drop audio and I get static. A restart works sometimes. I even got the audio drop while the welcome to Tivo was playing after a restart. I get the audio drop on video that played fine before. I have switched my cables around, connected the tivo to my TV with patch cables and coax sames issue. It is getting worse to the point that the Tivo is becoming useless. HELP!!

It looks like you might be headed for a hard drive replacement.

Came across this thread while looking for a lost audio thread (every once in a while my Tivo loses ALL audio, the only fix I've found so far is to reboot the Tivo) but to go back on topic for this thread, every once in a while my audio goes very squealy/screechy too, I don't know if it's the same problem as reported here because it's not the fan, it's the reciever the Tivo is hooked up to. Somehow the reciever goes out of whack with the Tivo, and I've got to pick a different audio mode. I've got a Harmon Karmon reciever, and it's normally set to the Dolby surround, but when this happens if I pick a 'faked' surround mode (called Logic 7 on my reciever) the squealy sound stops, and the reciever (which somehow detects the Dolby surround feed) switches itself back to the Dolby mode, problem solved till the next time.

My series 2 exhibited this tinny distortion yesterday. I've had it since the series 2 first came out and this is the first time the audio didn't work right. I even transferred a show over to my series 3 and the distortion was still there so it is in the encoding side of things. Live TV also sounded tinny. I cycled power on it and the problem seems to have gone away.

Audio sounds like kazoo intermittantly

After reading the comments on this problem and verifying that it did not exist if I bypassed the tivo set, I moved the tivo to the top of the tv where it got plenty of circulating air. The problem seems to be gone. It must be related to high temps.
