sprint touch pro cant charge n use headphone simultaniously anymore! Please help!

hello all,
I have a sprint touch pro, and i use the HTC adapter that came in the box.
just recently I tried plugging in the charger while i was using the 3.5mm jack on the adapter and what endded up happening was that the audio out got disconnected (the physical cable was still in place, but the phone thought that the headphones were disconnected)
this has never happened before, I've been able to use the audio out(3.5mm) jack and have been able to charge simultaniously.
I just installed .977 radio app and the pandora app.
I also tried this with the htc headphones and the htc charger on the adapter and the same thing... no luck. the phone cannot charge and perform audio out at the same time anymore. i have tried multiple adapters butt no luck. Please help!
How can I fix this? any of you having this problem?
there has to be a registry string to fix this issue.
thanks in advance!
I'm having the same issue but i'm using a BT Motorola headphone. Even though the phone is plugged in to the wall jack. The battery drains to 0 and then shuts off. Not at all sure what's happening either.
wow, thats not good.
has this been happening since day one or did it just started doing that?
Also, do you have the pandora and/or .977 radio app installed?
Well, I just bought the new bluetooth headphones and tried listening to the streamed radio while still having it plugged in, so this is new behavior to me.

My phone shows me that I'm on headset

Hi!
That's a funny thing with my p500 - it's showing me that I'm on headset even when the headset isn't plugged in. As a result I can't use my phone's speaker.
My ROM is mik-os' CM7 and I noticed my issue after changing some options in DSPManager and now I can't say for sure if this is a hardware or software problem.
Phone shows headset mode
Hi
as i think that its not your issue of ur rom, its usually occurs when the headset detection switch stucks ON which is present in 3.5mm female jack. try your headset plugged in n out twice or thrice its solves. or it remains same then apply a little bit alcohol over the male jack(as its seems to be slightly wet not more) and then plugged in and rotate it in clock wise and anti clockwise direction, then its working ok.

[Q] S3 auxiliary audio issue - any suggestions?

Hi ,
I recently upgraded to the Samsung Galaxy S3 ( UK ) , and for the first time today have connected it to the auxiliary input in my car stereo.
Before this phone I had the Galaxy S1 and all worked fine with no problem.
There are a few concerns I`d like the answer to and hoping that someone here can shed some light on it.
First of all, the battery on the phone was low when I left home, so I plugged the phone into the car charger ( one that accepts a USB cable, and was charging through that ). My first dissapointment was that I STILL got interference from the charger when playing audio , i had hoped this may have gone away since I was charging via a USB cable, but I still get a hiss in the background that is more apparent during quiet moments of songs - this is not such a major issue as I was used to it with the S1. Still, if anyone knows how to prevent this I would be grateful.
Anyways, the noise was becoming irritating so once the phone had ample charge to see me into work I disconnected the charger.
When I did this, the audio level dropped noticably and seemed to become more `tinny`. Why would disconnecting the charger cause this to happen?
Also, some tracks seemed to almost totally lose vocals , for example when Foo Fighters `The One` started playing it almost sounded like an instrumental. When I plugged the charger back in the audio level increased but still sounded odd.
When I got into work I plugged my PC speakers into the phone and it sounded fine through that. This would indicate the problem lies in the car somewhere, however I never had this problem with the S1.
When I plug the 3.5mm cable in , the phone detects `headphones` rather than auxiliary, I am sure the S1 used to notice accurately if the device attached was headphones or auxiliary. However, anything plugged into the S3 shows as headphones.
I am using the Android Poweramp app, which i absolutely love, so I would rather not change that as a solution - but I will try a different player later for diagnostic purposes.
Short version of this post -
1) How can I get the phone to detect auxiliary is attached and NOT headphones - I`m sure this affects the output level.
2) Why does the volume level change when the charger is disconnected?
3) Why would the audio sound like the vocals have been muted in the car when its fine on headphones and PC speakers?
4) Is there a way to get rid of the annoying interference hiss when charging whilst playing?
If anyone can help with this I would be most grateful
Many thanks
Ade
Guess I should have done a little more fiddling before posting!
The problem was a faulty audio cable , it just threw me how the volume levels changed when the phone was been charged. I still find that odd.
Anyway, sound quality and volume levels are fine now. I also learnt that you can disable the headphone notification along with the app suggestions in the notification window. This was in Accessory in the phones system settings , just uncheck the Audio Applications box under Earphones. I expect everyone here knew that already though!
The only issue I have left is the interference noise from playing audio while charging, I suspect I may need a more shielded charger or cable?

Google now popping up upon plugged in headset

Nearly every time I plug in my headphones (there's no mic on them), this thing pops up. It was a "meh" at first, but now it's plain annoying. Does anyone know how to stop this screen from popping up?
I had this problem on the LG G3 and G4 -- Google Now or Voice Control pops up intermittently when using headphones or an audio cable. Purchase a set of headphones with a mic. I also had to buy an audio cable / mic for my car. This solved the problem. Cheers.
I'm having same problem when plug it to my car using aux cable. But never has this issue when plug it to my bose via aux.. Probably because my bose aux cable has mic?
Same thing happens for me.
It acts like there is some static when the cable plugs in as I can get the same effect if I spin the plug and get static.
Settings --> Smart Settings --> Accessory --> "When earphones plugged in".....
I hope this helps.
I have that setting turned off and I still see where google now pops up when I plug/static with my headphones.
Hello, I have the same problem with Google Now opening everytime I plug in my earphones. Is there anyway to stop this happening? I have Smart Settings turned off. Thanks.
Try touching the end to something metal to ground it. Worked for me.
It seems it has something to do with cheap aux cable? My aux cable in my car is pretty cheap one, the other one that i use with bose soundlink, bought in Japan.

USB Dac in Car Tablet strange problem

I have an Android Tablet with Android 6.0 installed in my car. My car has a aux input in the factory stereo so I've connected the USB dac (pictured in the attachment) in the DC power USB hub that connects to the tablet using the OTG cable. I further split the output of the dac to seperate the Mic and Audio. Every time the tablet wakes up from sleep the DAC is detected but there is no sound i get a buzzing like sound. If i disconnect the USB completely and plug it back in then it works perfectly. I left it unplugged and plugged it in after the tablet wakes up then it works fine. But for some reason if it's plugged in to the USB before the tablet wakes up then it gives that problem. Does anyone know what the problem can be? I forgot to mention it's connect via a short USB extension. One thing I can possibly do as a work-around is cut the power to the USB extension and have some kind of delay on it so it doesn't start up straight away when tablet wakes up.
Also, I have a high gain car mic connected to the mic side of the splitter but the mic just doesn't seem to work although the mic works when i try the DAC and same setup on my Samsung S20+.
Any help and suggestions would be great. Thanks
