I upgraded my XDA IIi Alpine with the Deathnoise ROM. All works well but now there is a strange sound problem.
If anything is connected into the bottom socket then there is no sound from the main speaker, only from the headphone socket.
Even if the other end is not plugged in to anything there is still no sound. As soon as I take it out he sound returns to the main speaker.
I've tried it with a USB sync cable and a mains charger. Sound worked with both before the Deathnoise ROM update.
The update and sound problem may not be linked at all!
I wouldn't be that bothered but not I can't run TomTom in my car and plug it in to the power socket at the same time!
The most likely explanation is a wire has shorted or moved in your power supply cable or the socket and the set now the set thinks it is connected to a car kit. Search the Alpine section of the forum as there is a good reply I remember seeing about the socket wiring.
Its definitely something with the socket on the XDA. I need to open it up for a good look.
Its a pretty annoying problem though. If it had a separate power in socket then I wouldn't to be bothered

That seems to be a charging and syncing station, rather than a full docking station (with its USB passthrough ports etc). Having said that, if it charges from the mains while connected with PC, as description implies, it will be exactly what I'm after. Not a bad price either. If it's the same one I saw a few weeks ago, the price has halved since then. Hmmm, might get two (home and work)...
EDIT:
No, the one I saw before was this:
http://www.gpsforless.co.uk/product_details.php?id=7558
With second battery slot. Doesn't seem to be available though. The other probably replaced it.
What is the function of earphone jack holes of station?
On the left side of Athena, there are three jack holes, i.e., earphone, miniusb, and vga out. However, the docking station only plugs into miniusb and vga out. It does not plug into earphone. However, there is a earphone jackhole on the right side of the docking station, but when I plug into that earphone jack hole, I did not get any sound from it. I can not use the original earphone jack hole either, because it was blocked when you set Athena into the docking station. I have a question that What is the function of earphone jack holes on the docking station if no sound coming out from it?
The audio output is also available from the mini USB connection on the Ameo, connection of a correctly wired addapter to the Ameo will mute the onboard speakers thus routing the audio to the addapter cable/ port etc. Either your unit is faulty or the dock unit is incorrectly wired -
When you dock the device try playing some music etc. on the unit and does it emmit any sound from its onboard speakers ? - Mike
I *DID* get two of the cheaper cradles for my Advantage. They plug into the mains with a supplied adapter (5V 1A) and the PC's USB.
The trouble is, the charging time seems to be as if it were charging from USB only - ie sloooow. This is despite the power light coming on when mains is connected (or when USB is connected). Does the USB charging override the mains charging? I've tried disabling the USB charging with a registry addition as described elsewhere, to no effect.
If I unplug the adapter the LED on the adapter remains lit for a very long time - several minutes at least. Even unplugging the USB and the adapter at the same time doesn't affect that - the LED on the adapter itself and the cradle remain lit, but the charging light on the Advantage goes out. Very peculiar.
For someone with a full docking station - how quickly does it charge? If it's at full mains speed I may upgrade to one or two of them (when finances permit) for syncing, and use these cheap ones as mere mains-only charging stations dotted around the house.

The Athena mini-USB also provides Audio-out like all other new HTC devices. This would explain why the dock only connects to the mini-USB jack. However then, you should get some audio noise out of the dock's jack... this seems not to work...
I've got a problem when I plug my phone into my car stereo as well as cigarette adapter.
I'm also got a kind of custom setup.
Audio
Honda Civic Stock Stereo -> CD Changer to Aux Input Adapter -> 3.5mm to 2.5mm adapter -> 2.5mm input on HTC Y adapter.
Power
Belkin Cig. Lighter to USB Female Port (From old iPaq) -> HTC Stock Sync/Charge USB cable -> MiniUSB input on HTC Y adapter.
So, when both the power and audio are plugged in, I hear a horrible hiss on my car stereo, not to mention a sound that varies in pitch to my throttle. When I unplug the power, the audio is completely clean. To me this seems like some kind of a grounding issue - to say that the Audio and Power both have seperate grounds, and bridging the two creates a potential difference in the form of noise on my Sound. Also to note: I only hear the noise when the Y adapter is plugged into the phone. With the audio and power plugged into the Y adapter, but the Y adapter not plugged into the phone, It's perfectly clean. I'm kind of baffeled.
The only solution I can think of is to gut the Belkin Power->USB adapter, and providing it from 12VDC elsewhere. I've got a tap directly below my passenger seat where I have a big power inverter tied to my battery. I don't know if I'd hear the same sound by grabbing my power from there.
Anyone with an engineering mindset have an idea? I'm open to suggestions.
If it was a grounding issue I would expect a buzz not a hiss...
Does it go away when you unplug the power and just leave the audio?
Go away or stay when the phone is unplugged?
It could be a bad adapter so maybe try another...
It goes away when I unplug the power, or unplug the phone. It's only present with audio+power both plugged into the phone.
I've tried powering it using the AC adapter and a power inverter - that sounds clean.
Fix?
I have the same problem and went out and bought a ground loop isolator from Radio Shack. It ran about 12.00 and it definitely got rid of the noise but unfortunately it noticeably affected the sound quality of my music and made it sound high pitched.
Perhaps buying a higher quality one will solve the problem. In the meantime, I've returned the isolator and just run on battery when listening to music. Perhaps I'll hit Ebay and see if there's a higher quality ground loop isolator.
Definitely a ground loop problem.
As devoe said, you can get a ground isolator and put in the audio line, but those are typically a simple transformer, and they often don't pass low frequencies very well.
You may be able to simply cut the ground going to the audio jack input. Not a perfect solution, but it sometimes works. But it usually requires a blocking cap in each channel. An experiment for sure.
A different power adapter might help. Or not.
You may also be able to add in a power plug that is wired directly to the radios ground and power. Then your power adapter plugged into that might have a ground that is close enough to the radio ground to not have a problem.
Me, I would open up the power adapter, and if it is a switcher supply with a transformer, see if I could isolate the ground.
I had the exact same issue. I believe it is called alternator noise.
01 Nissan Maxima with Eclipse AVN 5435 RCA hook up. When cigarette lighter and audio are both on, it makes the noise. I dont think it happened in the beginning but definitely happens now....
Luckily my Kicker 12L7 overwhelms the noise and allows me to tolerate it...somewhat.
When the audio wire and power wire are close to each other, this problem happens. Intead of using an isolator for audio wire reducing quality, try shielding your power wire instead. Might work but not very sure..

What he said. The fact it alters in pitch with engine speed says it's alternator wine, which is related to grounding issues. I have a similar problem, but it's not a wine that follows RPMs, just a static like hiss. I need to dink around with the ground and see if I can get it.
I had a similar problem. I hadn't used my car audio for a while and when I started it up again, it was making horrible noises. I bought a new charger and had significant improvements. I'd recommend buying a charger from radio shack. If that doesn't fix it (or if you find it cheaper online), then you can return it.
If you can, verify the grounding cable on your cigarette lighter. Best thing you could do it to cut it and look for the nearest solid metal ground point in the lighter's general vicinity and ground it to that. Could be the stock ground on the plug.
I'm a car audio buff and my previous car, a 01' Camry had that issue when I charged my Creative Zen touch and played audio through it as well... Fixed it by re-grounding my lighter plug directly to the chassy, its just a matter of finding the right spot nearby to ground it with a good sized gauge wire, like 12 or 14 AWG.
I had a similar problem. I discovered that my problem was that the Mogul's CPU noise was conducting out the USB DC power cable and then coupling back through to my FM transmitter on it's DC power cable. I never was able to completely get ride of the noise. However, I was able to reduce it substantially by using a different USB 12VDC power source. USB hubs normally contain low pass filters on the USB power lines, so your mileage may vary.
The tick to solving your problem is to try different configurations by moving and disconnect wires. Often you can here noise variations that will indicate whether the noise is external to your system.
EMI is either conducted (ground loops) or radiated. Since audio is below 1MHz it is best if there is only a single ground point. Since you normally have multiple wires, ground loops are common, so keep your wires short and your devices close together.
Same trouble here, but on a Touch Pro...
I play music all other times and when it is charging in the house no problems right threw the phone speaker. But when its charging in the car no sound threw the phone speaker..
Any help?
Chris
are you using a USB splitter in the car that has a headphone jack on it?
No but i have a splitter with the usb charger slot and the usb headphone slot and when i use that it also does not work with the car charger and the headphones plugged in it charges but no music... And with no splitter and just the car charger plugged in and charging no music threw the phone speaker.. But at home when it is plugged in to the charger i get music threw the phone speaker
What make and model car charger?
I'd imagine since most people want to listen to music from the phone over the cars speakers (rather than out of the phones tinny speaker), your car charger has some means of hooking up the TyTN Is audio output to your cars speakers and so takes away it's audio but just currently doesn't have anywhere to send it. If you read the instructions for your car charger or have a look on the manufacturers website, that may help. As you haven't listed the charger make and model people with experience of your exact situation with the same item wont be able to chime in with how they sorted it but I'm surprised you dont want the better sound quality that comes from using your cars speakers
With the headphones plugged in directly (not via the splitter) do you get sound through the headphones as expected?
Yes headphones plugged in direct work fine.
I will check out the chargers website
Well it works now but i didnt do nothing i woke up and plugged into car charger and worked lol.. oh well
thanks all for the help.
I purchase the i.trek mini usb headphone adapter. This one:
http://www.amazon.com/i-Trek-Stereo...1?ie=UTF8&s=electronics&qid=1229612945&sr=8-1
I only get sound out of my right headphone from it. Tried messing with some settings but no luck. I am running PPCultimate ROM. Any suggestions? Thanks.
try plugging the usb part in really really hard. sometimes when mine gets a little lose, it becomes mono
I have the same issue.
Stereo works great with my BT headphones, but hardwired through the USB port = only one channel.
I've wiggled and jiggled the USB plug to no avail.
No problem charging or synchronizing via USB.
I found a pinout for the HTC 11-pin USB at tracyandmatt.co.uk that shows which pins are for audio. From the battery compartment, with the battery out, I can see where the USB connector is soldered to the main board and it looks like the previous owner had a battery leak or an overvoltage. The trace for "pin 6" looks to be toast.
My microsoldering skills are untested and I don't think I trust anyone else enough to do it.
I've got some problem with this cradle,
its strange cause if the delivered charger is put into the mini usb its loads the HD2 only if I use the "charge on usb" option in power settings but if I plug in the normal Leo charger on micro usb port (which normaly is for data) its loading like usual... are there any wires wrong ?
no one out there?
Do you have a spare battery in there? I thought mine wasn't charging at first too, but that was because my second battery was charging. I only have the supplied charger plugged into the mini-USB port.
I haven't tried what happens if i connect both micro and mini USB to the cradle and i don't have the chance to do that anytime soon, might be an idea though?
Annoyingly, the HD2 sounds were played to the 3.5mm jack when plugged in (which i don't have connected to anything yet), so my alarm wouldn't sound. I found the setting where to route the systemsounds (either to device or external), so that's no problem anymore

i found someone here in forum who has build a switch to change between sync and charge mode with the cradle delivered charger, but he doesnt answer my question how he did it....
nickname is Donald24
hi,
the hd2 recognise a 'real' charger at the fact that pin 2&3 (the data pins) are shortend. so it can achive more then the 500mA that it can get from a (PC)usb port. at least at my charger things are handeld that way.
regards mad

okay I managed to change my car charger this way but I'm not shure if I shorten the pins in the cradle with a switch to change between fast charge and USB connection if there will be some trouble with a connected PC...
