A100 Audio/Sound Stereo Problem

Hi Everyone,
I recently purchased iconia a100 for the following purpose:
1. To be the GPS in my car
2. SHow me over ODB interface (ELM 327 BT) all that i want about my car.
3. To be my car entertainment (Audio / Video )
In terms of first 2 : everything is great and works great (gps signal was real sh*t until i flashed flex rom).
The 3rd point is also great with one exception:
When connected to car amp (via car radio) or (for the testing purposes) any other expernal speakers or headphones the sound is only good on one channel.
The other channel is VEEERRRYYYY low. almost no sound there.
I actually bought Acer dock station thinking that this might fix the issue but.. no....
Its the same thing even via the dock station same channel is very low.
Anyone has similar problem ? anyone heard of a similar problem ?
(from what i can tell when the sound comes out of the internal speaker both channels work just fine.... yeah just checked with stereo test and its all good when on internal speakers)

What do you mean by channel?

He means left and right channels. I was going to say a hardware issue with the jack but the dock also shows the issue, and it does it with anything else? Headphones different cables etc?

and yes again, tried it with docking station and without and with both tried with my logitech speakers headphones and othe rheadphones
i listened for a bit more and realized that the sound comes form both channels one (left) lower then the other and on top of that its mono.
I've taken the tablet apart : back cover the battery and the volume controls pcb with the headphone port the latter wat disconnected during the test to make sure that the port is not affectin the sound (factory diffect during soldering and there is an semi shortcircuit between the channels) and it did not make any difference.
One other thing that it could be a something wrong on the board (soldering mistake ? ) right after separation for internal speakers and headphones/doc.
if it cant be fixed easily i think ill just simply remove the speakers and use that output (i dont really need the speakers when its in my car )

Mine works perfect in my car .
Are you sure its not a setting in your music player ? Sure its plugged in fully ?
Is your jack dirty or clogged ?
Is Dolby on ?
How are you connecting it to your deck ?

[Q] Issue With Headphone Jack

Hi, I've been having a weird issue with my headphone jack that I was hoping someone might be knowledgeable enough to help with.
Long story short, I haven't been able to use headphones for a while. Any time I plug in a set of headphones, music will, most of the time, come out of the external speaker as if there was nothing plugged in. Every once in a while I am able to get music through the headphones, but it is extremely distorted, almost as if some of the frequencies are missing and you're only getting part of the range.
Now, the weird thing is that my phone works perfectly in my car using an aux cable. Just plug everything in and music runs through the car's speakers as if there was no issue to begin with. This gave me the idea of trying to use a female-female connector to plug the aux cable into the phone and the connector, and headphones into the connector. This does not work at all.
I'm completely at a loss as to why this is acting up. I really don't want to take it in to a repair place, and would be willing to try fixing it myself if someone was able to isolate the problem.
Thanks in advance.

Check your headphones first. It may just be a short in your headphones

Unfortunately it's not the headphones, the same issue persists over 5+ different pairs of all types.

Well, it took a while, but after updating there is no difference from before. It seems like it's having trouble detecting that headphones are attached, but no issue with the AUX input.

[Q] Finicky connection with car audio jack

*Edit:*
Just so those who just joined in this converstation don't get too dragged into it, I've resolved this issue simply by buying what is called a ground loop noise isolator adapter. It's main purpose is to remove the static and whining noise you hear from your speakers when you plug your phone to the car charger while connected to the speakers. But at the same time, it is keeping the signal from the aux cable of your car on "hot" so that when you plug in the phone, the phone immediately picks up the aux signal and stays connected. I basically killed two birds with one stone by getting the adapter. Here is the adapter I purchased:
http://www.amazon.com/gp/aw/d/B001EAQTRI
I will make it clear here that this aux connectivity problem has nothing to do with how cheap or expensive your aux cable is. You can use the most expensive cable or the cheapest penny cable out there and if the problem exists between your phone and your car's aux, then it won't resolve it. Either change your car's head unit (which is a stupid thing to do) or simply get the adapter. Don't return the phone over this problem, its just a dumb move. The phone is amazing. LG will have a patch for it or someone will make a ROM that tackles the problem.
*end edit*
Hello all,
was wondering if anyone else with the G3 (not sure if it matters, but I have the 851 variant) is having a hard time getting their phone working with the audio jack coming from their car. I drive a 2007 Scion tC and never had any problem of weird issues connecting any of my previous phones (Moto Atrix 4G, LG Nitro HD, GSIII, Nexus 5 just to name a few) to the audio jack in my car. I'll just plug it in and it connects just fine.
But for some odd reason, the G3 is having tons of issues. When I plug in the audio jack to the phone, I see the audio jack icon pop up up top next to the clock, but then some times it will just disappear on its own. Other times, it will stay there, but when I play a media, may it be music, or video from any app, the sound will play out of the speaker on the phone and not the car speakers. Unplugging it while the media is playing and replugging it again will not change anything, but if I stop the media playback, unplug it and then plug it back in, and the icon reappears and then I tap play immediately, the audio will then come out from the car speakers. Some times I have to do this multiple times to finally get it to work.
The strangest thing is, this does not happen if I plug anything else to the G3, such as a headset or an external speaker or any other devices, only in my car. It even works fine in any other car as far as I know. I've tried different audio cables in my car but it still does the same thing, so it doesn't seem to be the cable.
Is there some kind of sensor in the phone that detects connectivity of the phone to another device? I realize that when I plug in the phone to my car, the car speakers makes a couple of whining noises before it goes quiet, sort of sending or receiving a signal from the phone.
Can anybody please help me? I want to say that the phone is defective, but I can't proof so since it works just fine with any other devices. Could it be the head unit in my car is incompatible with the phone? Any advice is appreciated. Thanks!

Thanks bfranklin, I didn't realize there was another thread about it. Wish all the G3 are under the same group.

I noticed i get some crackling feedback when i hit play on a track.. but then it works fine and even with moving the aux jack it doesn't keep cracking... just on initial play/loading of the music player

I have to plug the cable in very slow or it won't work.

That was my trick initially but eventually even that didn't work. Someone mentioned to try plugging in a charger first and then plug in the aux cable and that worked. But now I bought a ground loop noise isolator and that has resolved the problem completely. I also don't get so much popping noise and no whining noise when I charge the phone while the car is running. Here's what I bought:

If you use low quality Audio cables like Monster sells it will be higher resistance than a quality cable and should register without issue. The phone struggles with discovering the connection.

I'm gonna disagree here bc I'm using a cable from a Wal-Mart discount bin, which is I'm thinking the cheapest kind available, and it doesn't work right.

I was not saying that. If you use Griffen cable at 14 . or monster cable at 20. Or rocketfish at 18. They all work the same. Just not buying that it is a cable issue. Hardware more like it. I actually just order a eBay cable for .99 cents to prove this totally wrong.

This has nothing to do with cables. I literally tried over 6 different cables and nothing worked between my phone and my car's aux port. Yet I used the same cables in my friend's car (old Nissan sentra) that has an aux port and they all worked fine with the phone. Also used a cassette aux adapter kit in my gf's sister's old SUV and it works fine with it.
This is purely hardware compatibility issue. Some head unit's aux port stays hot at all times, others don't. Some probably reacts faster than others and connects immediately so the phone doesn't drop connectivity before engaging. Again, like I've mentioned, you can either circumvent the issue by using the "charge phone first then plug in aux cable" trick, or simply buy a ground loop isolator adapter which keeps the connection hot. LG will fix the problem eventually. It was an annoyance, but a minor one, and i can't be any happier with this phone despite of the connection issue.

Static noise when headphones are plugged-in

Hello,
So I have my Zenfone 2 since some months now and since the start, my phone has a problem:
When I plug earphones or headphones, there's a static noise on the left earphone (or on the left side of the headphone).
I contacted Asus, they told me to update my firmware, which I did (I even updated to MM today), but it didn't fix the issue. So they told me to RMA it.
I'm just posting this to know if someone here got the same problem and if he fixed it. I saw a post on a forum which said to deactivate every single sound (notification, etc) and only activate multimedia sounds. For some reason, it worked, and I didn't ear the static noise again but some days later. I tried to do this operation again but it doesn't seem to work.
Thanks for your help,
Best regards,

Hello!
I tried to see if there was some dust in it but couldn't find anything. I, however, used the pin but the problem still persists
I noticed that when I was plugging in my earphone, if I plug in "at the middle" of the jack, there will be sound on the left earphone but not on the right. If I plug it in completely (when you hear the "click" sound), then there'll be sound on the right but not on the left earphone, like I first said on the first post. Maybe this can help you.. I'd like to not send it but if I really have to, I will ._.

You can clean it with a compressed air can, the kind that is used to clean computers. I have one at home to clean my keyboard from tieme to time and have also used it to clean the headphone jack, since it doesn't use any liquid. You can get one at the local computer store or online from Amazon and similar sites

Hello,
Fortunately, I had a compressed air can at home. I tried to clean it with that but the problem is still here
Thanks for your help though, I really appreciate it.

So I "resolved" my problem.
Since I think my jack is broken, I bought this on Amazon. So I did a little setup so I can properly hear music/sounds:
I have a Logitech G430. When I want to listen to music on my phone, I plug my earphones on the G430 adapter, then I plug the USB cable into the USB-microUSB adapter I just bought, and I plug the microUSB cable to my phone. And it works perfectly!
Some may say It's a pretty rough setup, but for me, as long as it works, that's perfect.

I'm sure a pair of cheap BT headphones is cheaper than that setup. Anyway, if you want to keep using your 3.5mm headphones (I would since mine are very nice and were expensive) you can also try a 3.5 to BT adapter, which is also a cheap and nice option. Music through BT is usually of less quality than through the audio jack, but it¡s better than nothing and you don't need so many cables.
Something like this: https://www.amazon.com/dp/B00UUDZSKE
That one is $19, but you can probably get a cheaper one from a Chinese store such as Dealextreme, GearBest, etc. I have one which I got on eBay years ago and I think it was worth something around €10

Heavy static using aux cable

So I've been using my tablet in the car to watch Netflix and Amazon Prime videos during various appointments for my wife and kids. Has worked great with headphones, but figured it would be even better with my car's audio system. So I ordered a decent quality aux cable off Amazon, a 2-pack actually, but it doesn't work! I get really heavy static with the audio barely audible in the background. It also only plays out of the left channel. Tried the other cable with the same result. Plugged that cable into my Galaxy S9 and it worked perfectly.
I've searched around for the past half hour with no luck. Seems some fixed similar issues with other Samsung devices by turning on the UHQ upscaler, or by holding Vol+ while cycling the power, but neither worked for me.
Any thoughts?

Sounds like a faulty jack have you tried twisting the jack ? As sometimes that clears the static ? if not then you will need to get your Tab S4 replaced via Samsung!

I did rotate the plug, but it didn't resolve the issue. I don't think the jack is faulty, though, since headphones work perfectly. Thank you for your response, though.

I may be totally off but...
I have been using an MP3 player (Archos Jukebox Recorder) in my car for years. Recently I thought to go modern and downloaded some music on my Samsung A3 (2017) phone. Connected the cable... and all I got was a lot of static noise with hardly audible (and bearable) music.
Of course, the MP3 player using the same cable still plays ok. Anything plugged into the A3 also plays fine.
I haven't yet sorted out what could have been the problem but it sounds awfully like yours.

Sure does!

Cables make a huge difference getting a cheaper cable often out preforms the pricey one! (That's no joke) Disconnecting the FM/AM radio cable gets rid of the static (Here in the UK that has done trick in the past) Also can you try switching over the plugs on the back of your head unit right into left, and left into right. Vice versa see if that fix it ?

Switched the cable and the static seems gone... Strange that the Archos didn't have this problem. But I needed to increase the volume to a surprisingly high level[*] to get a decent sound.
