Hi there!
Looking at the "connectors" page, it seems possible to me, to tinker a cable/plug for external line in; for example for a microphone - or, which I intend to do, for a guitar pickup, so the tuner software I bought (which works very well) will also do it's job fine under "real" circumstances (before a gig, when the surrounding always is pretty noisy).
But there are some questions:
- which way to go, with a large or with a headphone connector?
- for the second, there will the internal speaker be off?
- for the first, there's also just the possibility to switch off both, internal mic *and* speaker? Or will line in also work, if CAR_ON# is not on +6V? But then the internal mic will be on and catching all noise, too?
- what means "Audio needs to be capacitively coupled in" on that page?
- which other pins have to be connected somehow, to somewhere?
- ah, and if going with the (easier to realize?) headphone connector - where to get one?
sorry for silly questions,
thanks,
Manfred J.W.

Can anyone help me with this:
I have always used my PPC's in my car connected to an external audio jack via a 3.5mm headphone connection. Not only did I use this for music, but it also allowed me use my car stereo to hear my callers much louder than the speakerphone was capable and still let me to use the built-in mic of the PPC to talk back.
Enter my Artemis and it's proprietary mini-usb audio jack...
I purchased the HTC mini-usb to 3.5mm adapter from expansys so that I could continue to use my in-car 3.5mm connection. Works great for music and TomTom (Austin Powers is scary loud now when he tells me to turn left!) BUT the built-in microphone in the Artemis seems to be disabled whenever the adapter is inserted in the mini-usb jack! I can't use Voicecommand with it inserted and my callers can't hear me until I pull out the adapter - which then takes away my nice loud car stereo to hear them!!!
Presumably, the disabling of the mic is because the mic in the included headset is expected to be used for calls when the audio jack is occupied. I know my configuration is not "standard," but it works (or worked) great for me and I would love to be able to continue to operate this way.
My question is: can anyone tell me which registry values control when the built-in mic is disabled? There must be a value that tells the Artemis to shut off the built-in mic when the headset is plugged in. I would love to change this so that the configuration I described above will work for me again. I have some trepidation about tinkering with my registry too much when I don't have that much experience with it. I hope there is some registry guru out there that will take pity on me and take on this challenge (if it's even possible).
Thanks in advance!
You'll have problems with something like this... I'd assume that it'll work similarly to the headset antenna registry entry, where on connection of the headset a key relating to the FM Radio software is changed from a 0 to a 1 allowing the application to launch.
There are one of 2 outcomes for you though unless you want to get crafty with a button or something to make the changes for you....
1 - Although you'll be able to change the reg setting, plugin in the usb cable or disconnecting it will simply reset the key,
2 - You'll permanently change it and if you want to use anything other than the handset mic you'll need to undo the change.
I'd say more than likely if it a dymanic key though and triggered by connection or disconnection of the usb cable then option 1 will take effect. I'm guessing that you'll need a button (software or hardware assigned) to control this properly.
Good Luck!
I'm too lazy to read.
Check the state and notification broker. Otherwise you'll probably have to directly interface with the audio driver.

Me too...?
Hi all,
I too want this fix, using the microphone whilst drawing off the audio feed for my vehicle stereo. Can it not be done with a soldering iron & external mic wired into the dongle adaptor?
Thanks Paul

Here is an adapter with microphone...
I suggest hacking a handsfree and making your own jack for the car. this is my plan soon!
Hi All,
I have the same problem with my HTC Diamond. Did anyone have a fix for this yet? As i do not mind changing the registry or if someone wanted to make a little program that would do this i would be more then happy to donate for all your troubles.. I'm unable to hack my fm transmitter as it is a holder aswell... see picture
Anyone with a concrete solution?
This seems to be a hot topic! Are we really sure that adapters with mic are not readily available?
If you're au fait with hardware hacking, haret can probably tell you which interrupts are being used and you can write a solution to poll the irqs that way.

There is nothing to do with Registry Hacking or Softwares in your case...

There is so many ways of soldering of wires (Line IN & Line OUT) using a mini usb to made your PDA more compact...
The built-in microphone in the Artemis or Any other HTC Devices sure have to be disabled whenever the adapter is inserted in the mini-usb jack for the soldering of 2 Line-Out (Audio-Out Left & Right) and 1 Line-In (Audio-In/Microphone) Example: Headset that come with your PDA.
Unless HTC going to make one mini-usb to two cables,one for 3.5mm adapter for headphone and another to Mic.jack or a Microphone itself.
This is quite difficult for HTC to custom a cable or jack for individual need.
I think you have to DIY for your need in this case:
Use the headset that come with your Artemis, the one that have a Mic and mini-usb jack...
Cut away the left & right earphone, soldering the two cables into a 3.5 jack (male or female)
Both this jacks-Male or Female can be found in electronic spare-part shop anywhere.
I'm new in this forum... please cc this Thread to me 'thru Private Messages, so that i can give further help and keep track how the going you guys out there...
Hello everyone,
I am trying to understand what is the key fault of my HTC Desire. I since have changed to a HTC One X, due the fact that my Desire has lost both full phone networking and sound capabilities. The rest of the device works like a charm, currently with Paranoid's Jelly Bean rom, even on heavy load.
The phone has gone through three accidental falls (bad luck serie), that required me to change the amoled screen only three times up to now. The original digitizer is still like new. After the last fall, it started to develop some sound issues before the two ones I expose here. It started with the music only in one of the headset speakers thing (by compressing the left part of the phone, I could get back music in both ears).
Rapidly, I discovered my Desire could no longer catch the phone network, and so could no longer be used for calls, SMS or mobile Internet.
Additionally, no sound comes out from anywhere : front speaker, back loud speaker, headphone. The microphone appears muted as well. The volume settings are all at maximum, including using a more complete audio manager app from the Market. Headset detection plug/unplug works fine.
So apart from the other functionalities that all work (screen, digitizer, vibrator, Wi-Fi, Bluetooth, SDCard , Sim card (detected and activated), USB, heavy load from benchmarks and games, volume buttons, camera, etc...), the phone is rendered useless by not being able to catch phone networks and not produce any kind of sound.
I have replaced some parts of the phone since this issue has begun : the upper board with flex cable (that was tired) and the loud speaker (was tired as well). It has not solved these issues (it only solved appearing detection issues due to the tired flex cable and failing volume buttons).
I now use the Z-device test app to try to diagnose the issue. I am not sure I understand them, but they may give hints :
- He is detects the SIM card well and displays its information.
- He detects the phone as gsm type, but is unable to display the gsm cell id (blank space). He finds the device id (long number) and the software version (00).
- Data state is therefore set to disconnected.
- Multemedia chip is undetected (blank space)
- ALSA version is undetected (blank space)
- SCO for off-call use is set to true
- Microphone is set to muted
- Speaker phone and wired headset are, whatever happens, always set to false.
This is it. I haven't got further yet. I try to situate the possible hardware fault, since full wipe and reflash has not solved the issue. I only have those suspects :
- What is called the Wi-Fi cable, that is damaged (the thin cable can come out easily from one of it's metal end, while it is clipped properly).
- What is called the antenna cover (that looks like yet another plastic piece, with two metal pins on the left side), the cover being slighly cracked on the right side but still completely screwable.
- One of the motherboard's IC chips or component for an unknown reason.
The phone is in good state and works well now, aside of these two key features. It does not look like it has fallen down once, a shame. What is your opinion on this? Do you have ideas or suspicions?
I thank you by advance.
About your sound issues (speakers, headphone), sounds like your amplifier died.

Probably. I doubt the isseu would come from the so called Wi-Fi cable as it may not both transport sound and act as an Antenna.
I therefore need to see if it is possible to replace the amplifier chipset. Might require precision soldering though.
Still idea concerning the gsm fault...

you would probably need hot-air to do that
Hey, I'm looking for a way to use an external mic to record audio on my Nexus 7 2013 LTE. I did a quick search and didn't find anything so I apologize if I missed it. Looking for an app or possibly a rom that allows me to choose what apps see as the default mic. I'm willing to purchase a couple of minor accessories if needed.
Specifically, I'm trying to record sermons directly from the tape out on a mixer. I'm pretty sure this device has a trrs audio jack if I understand correctly and I already have a trss adapter that splits audio in and audio out, I just cant figure out a way to make an app use that mic input rather than the internal mic. I don't care what app is required as long as it's not outrageously priced as I'm paying for this myself.
It depends on what kind of microphone you're thinking of using. But so far as I know, plugging in a phone type external microphone would automatically cut off the internal and use the external instead, as in using app like skype or voice recorder. What do you need a special app for?

the "mic" would be a tape output from a mixer
Hi, I wanted to ask you to help me if it is possible with a problem.
I try to explain everything briefly.
I have a s160 for Kia Sportage model M537-1 with Canbus, but I'm not good at both sound quality and low volume.
After months of testing (I also changed the woofer and tweeter of the car) I realize there is a chance to make the sound almost perfect.
Entering the factory settings (## 0323) by clicking "Select External Power Amplifier", you will see 4 options:
- Built-in adjustable
- External adjustable
- Build-in Fixed
- External Fixed
(My car has as standard a small amplifier on the back made by Kia's mother house)
Using the "External Fixed" option, low audio and poor quality. By switching to "Built-in adjustable" the sound becomes perfect for quality and volume !!
The problem is just that, once I turn off the car and restart, the audio disappears.
Contact Roadnav and tell me that the only option I can use is "External Fixed," because "Built-in Adjustable" is an option that unlike Built-in Fixed and External Fixed does not send the power-on command to my amplifier Series, this is why the sound is "silent".
Now I wanted to ask you, there is a way to change the "Build-in adjustable" option in the firmware, maybe by taking that string or code from "External Fixed" which allows the amplifier to turn on when the car is switched on.
It would be a great thing for me, but also for all those who have this car for Kia Sportage. If you have other tips to improve the situation I would be happy. Thanks
I recently installed a Xtrons PQS90MTVL head unit in a skoda superb. I have a couple of questions on how to get it to work correctly when navigating.
1) It seems that you can set the navigation sounds to be a percentage of the radio volume but cannot set it to play at a given volume regardless. The problem is that the radio seems to be constantly on and there is no way to turn it off. The 'on/off' button simply mutes the radio - and the navigation sounds.
Often I am in an area where I cannot pick up a decent radio signal on the programme I want and just get static. In these situations I want to turn the radio off but still hear navigation sounds. I don't want to listen to loud static just so I can have the nav sounds play at a percentage of that static. Is there a way to turn the radio off but still get navigation sounds? (a workaround I have found is to play a media file instead of the radio and then pause playback. The nav sounds are then still a percentage of the - non existent - playback volume. However this should not be necessary)
2) It also seems that a Internet connection is needed for any navigation. even google maps won't do a search without it as it says I am offline. (is this true?)
I have bought the 4G wifi dongle but have a question about its use. Does the HU connect to the dongle, as far as data is concerned, via the USB socket that comes out of the back of the unit or is that socket simply powering the dongle and the HUI is actually connecting to it over wifi using the dongle as a hotspot? If so then I don't have to use the wired usb socket from the unit (which I suspect is underpowered) and can plug the dongle into an ordinary 2A USB socket that I have in the car, positioning the dongle near the roof for a better signal
Incidentally I did try using Android Auto with my phone using wired connection. That seems sort of OK but is not very reliable. Often when starting the car it hangs at the 'connected' screen, or even at the 'trying to connect' screen, although other times it seems OK
3) There is a small socket on the left hand side of the HU that looks like a slot for a small memory card or a sim card. It is labelled 'GPS'. What is that socket used for? it is not mentioned in the manual as far as I can see. - The manual is generally a bit hand waving though, excitedly telling you what you can do but not how to do it.
(I did try the xtrons forum but not only are the last posts there around January 2022 but there seems to be no way to register for it. Hence posting here)

All I know is the model is Xtrons PQS90MTVL so maybe its MTVL (whatever that is) I'm afraid I don't know what mcu means so cannot offer any version for it. Its possible I have posted this in the wrong section and have rep[osted in 'Android Head-Units'. If that is the right place and this is the wrong place, please can you delete this post
