    Four of the cables from Amazon have a cost of $17.88. My two sets of cables from TiVo, including shipping and tax cost me $42.27. So that would have saved me $24.39.

    Although that was before Amazon started charging tax in Virginia. As of 9/1 I have to pay tax on Amazon purchases so it would cost a little more for me to order from Amazon now.

    The colors are already set up for the audio cable. Red and white for right and left audio channels.

    Audio is from the connection that has the composite video output.

    Yes, but the breakout cable being used is intended for composite and so there is only 3 of them. So I'm guessing there's a 2nd breakout cable with the 2nd Mini analog output being used for audio.

    There are two output ports. One provides RGB from the three RCA cables(labeled component) and the other one(labeled A/V) provides stereo audio and composite video from the three RCA cables..

    I had an old Tivo breakout cable from years past that seems to work with the Mini.

    The colors are a bit off as White/Yellow seem to be swapped (or at least yellow is one of the audio's, dunno if it's R or L yet :)).

    Anyway, I have the two audio chans hooked up to my receiver's input (it's an old one w/o HDMI). For most TV channels, I get audio out of both speakers. When I'm in the Tivo menu though and clicking around, the Tivo ding/bong only comes to the right speaker though.

    Also, some shows/channels appear to only have sound in the right speaker.

    Any ideas? Is this normal...?

    A\V output only. Video to TV is via HDMI. I don't use the composit out.

    We used a Samsung LED TV Breakout Cable to make it work. Seemed ok.

    I'm getting the horrid buzz WITH the tivo branded breakout cable. BOOOOO. Any fix for this? If not I'll have to return the mini. ..

    I don't have their cable, but I used 2 from Amazon and they work fine. I did have to play around a bit to get them matched the right way, but mine have white, red and yellow for both of them. I currently have red to off red, white to blue and yellow to green, in case that helps. Everything is fine.

    If you still have problems it is likely a problem with the cable, mini or your TV. Get the right one replaced and it should work fine.

    Thanks for the reply.

    If I understand you correctly, you're saying that the horrid buzz you experienced was fixed by experimentally swapping where the plugs of the breakout cables were plugged into your TV until you found a configuration that worked?

    My understanding was your buzz was coming from the A/V plug (breaks out to left, right, and composite video), not the component video plug. The component video is working fine for me, but I am getting the horrible buzz from the A/V plug. I will try swapping the wires around but since I'm using the Tivo brand wires and taking red --> red and white --> white it seems like that should have worked. I'm getting stereo sound, but with a loud background buzz.

    I know it's not the A/V receiver because it plays other sources fine through that input. I do have another cable set because I accidentally bought two; I will try the other cable.

    If that doesn't work I guess I will return the mini for a replacement. Maybe something is shorted out internally.

    Here's another random factoid: in the course of troubleshooting, I tried plugging in a two-conductor (earphones) miniplug into the A/V Breakout jack, and there are positions of that plug (partial insertion) that yield clean mono or stereo sound with no buzzing. However, there is NO position or amount of manipulation of the Tivo-branded three-conductor plug that gives clean audio. (unfortunately, full insertion of the two-conductor plug leads to buzzing, so that is not a permanent solution).

    Thanks again for the help!

    I don't remember exactly what happened, I just remember that I had some big troubles until I got things plugged in right. YMMV of course.

    It could be that this does not apply to your situation. It would be nice to try a replacement audio cable in your case. Your description here does make it sound like either the cable or that port in the Mini is messed up.

    Does the TV have just the red/white/yellow connectors? Have you tried that? How does the sound work in that case? It would seem to imply the problem was outside the cable and Mini port if that worked.

    HUGE troubleshooting breakthrough - buzz goes away when coax (I'm using MoCA) is disconnected from the mini...

    off to the crawlspace now to see where the coax is coming from...

    I'm having the same issue. I wonder if it can be fixed at the TiVo end instead of somewhere else in my coax run.

    There is hope! I bought this at Radio Shack (stereo audio ground loop isolator):

    http://www.radioshack.com/product/i...&cagpspn=pla&gclid=CPHFo4K3mrwCFQt1QgodegUAjg

    And it worked! for the Audio. I am still getting some pretty severe banding (scrolling lines) on the component video. So I ordered this (coax ground loop isolator):

    http://www.amazon.com/gp/product/B0070Q6URO/

    I'm going to try hooking it up at the Tivo Mini (since this is the only place in my house where the ground loop is a problem). Don't know if it will work, or if it does whether it will kill MoCA.

    If that doesn't work, I think an HDMI -> DVI adapter should do it. I have a DVI in on the TV, and I've never had any banding with that input. And I have the audio sorted separately as explained above.

    I have learned a lot!

    Good luck

    hsawtelle, not to scare you, but your symptoms are likely caused by improper grounding... either in the cable system, or in your home's electrical system. The differences in the level of "ground" causes the hum.

    On the cable tv side, they used to drive a rod into the ground and attach it at the point of entry. More commonly these days, in residential settings I've seen a grounding wire run to a water pipe in the basement. (Google pictures of coax splitters and you'll find lots that have a ground screw on em.)

    Long-term, the current flowing through anything connected to the two systems probably isnt going to be super healthy for them.

    Google "ground loop" and "open ground"

    A friend of mine, a good number of years back, blew up lots of equipment until they diagnosed that his whole house mis-wired, was trying to dump a lot of power into ground, and wasn't grounded... *boom* goes the cable box, receiver, tv, poor cable installer guy who got zapped, etc.

    To quote wikipedia:
    "In an electrical system, a ground loop usually refers to a current, almost always unwanted, in a conductor connecting two points that are supposed to be at the same potential, often ground, but are actually at different potentials.

    Some of the most notorious effects of ground loops are the noise and interference that can become present in audio, video, and radio transmission systems. They can also create an electric shock hazard, since ostensibly "grounded" parts of the equipment, which are often accessible to users, are not at ground potential."

    Not scared. Thanks for the info.

    I've lived here 10 years with many devices hooked up to cable & power; nothing fried (or failed to work for that matter) yet, so I don't think my issue is as severe as what you've described.

    Swapping my Comcast box for this Tivo Mini is the first time the problem has come up in 10 years. I'm sure the problem is likely systemic, but if I can fix it at the one point it's causing trouble, I'm totes going for it.

    Final update: the cable ground loop isolator (Amazon link above) worked great and solved the audio buzzing AND video banding issues. I screwed it right into the back of the Mini and screwed the coax into the isolator. MoCA connection is still strong.

    Returned the audio GLI to Radio Shack.
