I tried my hdmi out put yesterday and there were small interference lines running through the tv screen. I was using a converter box to switch the hdmi to rca because my tv isn't hd. The cable I was using was a cheaper version baught on amazon from the oem shop. I was figuring the lines were caused by the converter box, but couldn't rule out the cable or just a buggy phone. Has anyone else had similar results?

The problem is likely in your HDMI to RCA converter. HDMI is a digital signal, even a cheap cable will work fine for short cable runs. A bad HDMI cable will produce blocks and black spaces or else no picture at all. RCA cables are analog and cheap ones can lead to washed out colors or noise. The converter itself may be adding noise to the RCA output. Ive used cheap VGA to RCA converters before and they can be hit or miss. The one I bought was a cheap Chinese knockoff and it wasn't even set to NTSC.
You also should realize that even when working fine the video from RCA is only SD so everything will look blurry and it will probably only be usable for looking at videos and pictures.

I purchased a Seidio mini-usb to audio cable and I cannot get output in both ears no matter what headset or combination of stereo adapters I use. If I hold a stereo adapter half way in the audio cable I can hear in both ears, but that hardly suffices.
Does anybody else own one of these? Do I just have a defective one or is there some secret I don't know?
Thanks

I know that my room mate has a pair and they work fine. I would assume that it is just a defective pair, or your port is messed up.
I have 2 pair. One worked fine, but the cable is so cheap it started to break after 1 week, and only an hour or so of use. I bought another, and only get sound out of one ear. I think you might need to by one of the HTC remotes if you actually want something with quality.

I bought this one, and it works great. Problem is that it's a bit bulky, but the cable quality is great. I bought one that just outputted audio only and it was small and skinny. broke in 20 minutes of use...
Look for one with a REALLY thick cable. The one above probably has one. The ones with "normal" looking cables on ebay actually have thread-thin wires that will snap in a week.
i have Seidio's 2-in-1 isolators, and they work fine for me, but it does take some doing to make sure the jack is fully pushed in. it goes in farther than the usual sync/charger cables. the main problem is the way it bends out at the jack, which prevents me from taking out my stylus easily.
Sorry if someone else already posted this somewhere... Looks like they modded the Streak PDMI connector into a mini-USB adapter.

Good idea but would be nice to see the inside and what wires soldered to what
I checked out John's website over at http://www.linuxslate.com, and while I don't have time to look at everything now, it looks like there's a lot more info there, including pinouts and pictures the board.
I'll read through everything later, and may have to order another cable from Dell to give it a try.

Instead of cutting up dell cords, anyone have a clue where we could get raw pdmi connectors?
I don't really see the point - you've still got to plug in the PDMI connector so what's the advantage?

Well, you have a point.
If you plug in a mini USB to USB-A cable into the adapter I made, you end up with exactly what you had in the first place (With the Dell Cable): PDMI to USB.
Furthermore, There's the cost:
Their way: Dell Cable: $20
My way: Dell Cable to destroy + Something to get the mini Female USB + mini USB cable + labor = >> $20
But, there are 2 points:
1. I have shown that the Pin-out of the Dell implementation of PDMI is known. USB breakout is just a simple demonstration. Manufactures can built lots of different breakout cables and docks.
2. It is far easier to carry the tiny adapter that I made than it is to carry the Dell USB cable. When I already have standard mini USB cables at home, in each car, and a couple at work, I really don't want to have to buy half a dozen $20 Dell cables, just to have one at each location I might need it. I can connect the little adapter I made to my key chain, and always have it with me, while hardly knowing I am carrying it. My little adapter is far more durable than a cable (especially since the Dell cables seem rather stiff).
He's another what's the point question:
What's the point of having Audio on the PDMI when there is already audio on the 3.5mm jack?
If I had a Audio/USB breakout adapter, I can make both connections with one action (such as when getting in the car.), and I don't have wires sticking out of 2 sides of the device.
Perhaps if you wanted to use your Sony Walkman Cassette Player in your car instead of it's built-in 8-Track deck, such arrangements were acceptable, but I was under the impression we had made some progress since then.
(For the record, I'm not old enough to have actually done that.)
Just my opinion, but I'd rather carry around an adapter that I could plug any one of my numerous USB chargers into (wall, car, etc...), than buy new chargers from Dell (especially at the prices they're charging for them).
-ag
I also would much rather have one adapter as shown except perhaps a micro-usb on the other side in addition... If we are going to have an adapter, make it multifunctional.
If we want to get really crazy, put a micro switch between pins 2&3 on the USB (or whatever the pinout is for data in/out so we can use any USB power supply, but open it for syncing if necessary
Ok, point taken!
So put me on your advanced order list for a micro adaptor ... I left my cable at home today and was out of power by 1 pm.

Another advantage if you could actually buy just the raw pdmi connector form some kind of electronic component whole saler like digikey or newark or something, you'd probably be talking about something that costs 2 bucks to make instead of paying 20 for a cord.
I bought the slacker G2 dock and tested i with the streak. Initially, nothing would work, no charging, no audio output. So i decided to take it apart and check the pin out.
So opened it up, took the board out and checked the usb pins, it was correctly mapped to the right pdmi pins, was dumbfounded why it did not work.
Then I just plugged the board in to the streak and lo and behold it started charging. When it was in the dock, I think the streak was not getting seated properly on the pdmi connector, because of the thickness of the plastic top cover. The headphones and line out ports do not seem to work though, I will have to do some more trouble shooting.
Keep us up to date on this.
I am VERY interested in this for desktop charging.
this would be HUGE, since if you don't need the HDMI out, why pay for $70 at Dell?!!
If there was some way to create an adapter that slid in flush with the phone, that would be perfect. Nothing extra to carry, just snap it in and you can use any mini/micro USB cable.
Get on that and let me know how it's coming along.
So did I see somewhere that the Samsung Galaxy Tab will be PDMI? If so Here is an accessory from it to USB http://www.engadget.com/2010/08/30/samsung-galaxy-tab-accessories-may-include-bluetooth-stylus-and/

now that will be very handy... keep one of those handy and most cable issues will go away
I saw that and the accessory port looked like a PDMI - I hadn't read anything, tho.
Perhaps we will see more as more devices have the plug.
perhaps Dell is on the leading edge more than we thought!!!
PDMI has been around for a couple of years but no one has used it until now, the Samsung connector certainly looks like a PDMI but it hasn't even been released yet so there's no way to tell for sure.
I saw that accessory for the Tab on engadget.
They copied me !!
Raw PDMI connector Part No.

I asked the dude who made his own PDMI to USB adapter if he has seen some markings inside the connector he used, no reply.
Could it be the Molex (or whoever is the manufaturer) part no is mentioned in the official PDMI specs?
I checked DigiKey and Newark for "PDMI" and got zilch.
Any one tried this adapter?

iPod connector is different unfortunately, although they look similar the pin layout is totally different

OP knows that. Visit the link. It is a converter that creates a usb port and an adio in port from ipod dock. This will let you plug your streak usb cable and an audio cable into the converter and then into the ipod dock. Seems like a good solution for anyone who has a bunch of ipod or iphone accessories sitting around.

stole my idea! I was gonna make one myself and then see if i could get into mass producing them but been really busy lately.
I want to make a iPod female to PDMI male adapter thats small (about the size of a matchbox but skinnier) but $20 bucks for an extra cable from dell?!
That'll teachg me to read links properly...
But you'll have to have your pdmi cable going into the streak to power it AND a audio jack plugged ito the headphone port for audio.
Definitely not an elegant solution.
Finally a speaker dock for our tabs http://www.amazon.com/Philips-AS851-37-Fidelio-Docking/dp/B005HY4UH8/ref=pd_sim_sbs_e_2
While it is a great idea, the price is in no way feasible. This speaker cost more than I paid for my Tab, the problem lies with Samsung and their product releases. They push too many tabs into the market at a time. I would sell my current Tab, the OG, and save 200 and buy the 10.1 inch Tab, but that's just me.
I just tried this dock on Sunday at Best Buy with my Nexus S... the plug is rather flimsy and made me nervous about leaving my phone on it. But the worst thing is that connecting it via dock connector doesn't automatically play music through the speakers (like iPod dock connector speakers do). You have to connect via Bluetooth. Apparently Philips has an app that goes along with this speaker, but I don't know whether it gives you that functionality.
Are you certain that speaker dock will accommodate the samsung connector? It's pictured with a micro usb connector.

No it has nothing to do with the samsung connector. This is a Bluetooth connection and streams the audio over A2DP profile.
This is pretty expensive for the price. You're better off finding another Bluetooth streaming speaker. I think Jawbone just came out with a wireless speaker for like $99.
Hello guys,
Somehow my brother messed up the cable and the little things that make it "click" when it's connected are gonne. It works but sometimes it doesn't
I was wondering if any of you has used it succesfully with another USB cable, I know it's gonna work since it's just a mico usb cable but I'm a little concerned since the original has something like a resistance in there that spherical thing along the cable.
Thanks

The casing around part of the cable is a ferrite core. It is used to reduce magnetic interference on cables. In the case of the Chromecast, they probably included it to reduce any chance of interference in your HDMI devices from the power to the Chromecast.
I wouldn't worry too much about getting one with a ferrite core, but Monoprice sells good quality cables and offers micro USB with the ferrite core.

They are good quality cables and also have a lifetime guarantee, but they're cheap enough it's probably easier to just buy a backup or two.

Thanks you so much for your well informed response, really appreciate it.
@raptir , do you think it's gonna be some trouble using a normal micro usb cable if the original cable doesnt work anymore? I'm thinking on getting one of these but I'm not sure if they ship to chile, need to find that out.
Without a ferrite choke you *might* get some audio or video interference. No damage, just the digital equivalent of static. So try it. If you get a bad signal then get the fancy cable.

I have a semi non related question. Would a cable with a ferrite core eliminate the interference you get charging your phone and playing music out the 3.5mm jack at the same time?
The ferrite choke, er, chokes, some types of interference from being transmitted on the cable it is on.
Thus if you've a junky 3rd party power supply it could well be spewing all kinds of noise on the line. Then a choke can help. However if the em noise is coming from within the handset then no, the choke will have no effect.
My advice would be to use the proper charger, from the OEM, and seeing if that makes a difference. If that corrects the problem you'll not only be able to power 'n play but also extend the life of the battery by charging it as it was intended.
