[Q] Loud "pops" when using the Samsung vehicle dock

Hi there.
I just recently bought my SGSII, and even more recently received the Samsung vehicle dock/holder with charger and line out. It seems like a quality unit, and it sounds very well when playing music etc, but there is a huge annoyance: Every time android initializes some sound, whether it be when the music player plays the first song, the voice in the google navigation program, or a system sound, a loud "popping" sound can be heard. I tried turning all system sounds off, but it's very annoying when using the navigation program. Has anyone had this same problem?
Other than this, the output from the unit is loud and clear (no volume issues), and there is not much background noise. I considered the wiring on my 2008 VW touran, but that should be good. I also tried it on another car (Jeep with an aftermarket stereo). I have used an iPhone with a similar style dock (ie one that splits the USB/dock connector to a charger and aux) without these issues earlier.
So, has anyone else experienced the same problem, or should there be no pops? Could it be a defective unit? Otherwise, could it be due to some bug in the OS? I have the latest official build from Kies. (2.3.5, I9100XXKI4, GINGERBREAD.XWKI8).
Thanks in advance.

I have a Alpine indash monitor and when I use the USB connection and hook up my phone and mount the storage ( to play music over my stereo) it starts to play a loud popping noise till it finds all the music files on my phone. For example if I have 50 songs it pops 50 times. Really really annoying cause I I hear is popping noises before my music starts to play

So is this with the USB cable straight to the GS2 or thru the vehicle dock's USB?

Samsung Norway just got back to me after having tested their own devices, and it seems they also had the same problem. So they just told me that that's the way this thing works. Which is very strange, I can't imagine they don't get more complains. Surely, noone wants ear wrecking noise before any message from the navigation app or music player?
Are there no fellow vehicle dock users out there who can confirm if this is normal?

I'm using the desk dock and I have the same problem, never found a solution, I tried several roms and kernels

Thanks for your reply. Seems very odd, almost as if there is some firmware/software problem, something emitting an audio signal that shouldn't be there. Let me see, wasn't there a thread about making your own usb to charge/audio out here...

I received the car dock the other day and have encountered the same problem. Any time the android system "does" something other than just playing the music, terrible loud pops occur.
Between this and the fact that the call audio is not routed through the dock's 3.5" jack has me considering returning it! I wish this fact was better explained in the Samsung literature on the dock.

I also considered returning the unit, but I think it might be a software flaw. At least, it should be possible to make a software workaround (drivers/firmware) for this, as it seems to be caused by audio initialization in the phone. Is this something for the developers? Do any of you have experience with same kinds of accessories with other brands using a micro USB connector as dock?

this has got to be a bad ground. the only time i get a pop is when i place/remove the phone from my dock or plug/unplug the usb power and i blame that on a bad ground for the usb adapter in my cigarette lighter.
if it doesnt pop while off usb power than its the ground plain and simple
edit: sorry for hijacking this thread but could you post a screen shot of the car home or desk home app?

I can't imagine this being due to a bad ground. Its a 3 years old car, and i've also tested the unit in a brand new Citroen c5 with the exact same pops. In addition the Norwegian Samsung people say its the same with their units. Out of curiosity, what firmware are you running on yours? I'll see if I can arrange a screenshot.

Audio issue in car using Line Out input in BMW

Has anyone else out there connected their M8 to their car using 3.5mm and noticed a strange whining and hissing noise prior to any actual audio being played?
The noise is very apparent, but as soon as you start some audio (Spotify/Deezer/Google/HTC player) its fine, and that includes any quiet bits in a song. Its when there is no audio being pushed out there seems to be this problem,
I havent noticed it on my headphones, but cant confirm as I left them in the office last week. Anyone else had a similar issue?
M8 is stock with latest updates for UK version.

Your cable must be loose or bad

Try a better shielded cable. Also, turn volume to max on the phone to get a better signal and adjust desired volume in the car.

I have tried several cables (one pro series) and it makes no difference.
I have only just upgraded to this phone a week ago from my Galaxy Note 3, which did not have any issues at all.

Are you charging your phone while it's connected?
Try it without power or with an external battery.

Unfortunately not, I would expect some interference if I had connected it to the 12V charger, but its just playing as a phone with only the audio lead connected, nothing else!
Most annoying is that you have to pay £240 more to BMW for audio bluetooth.... grrrrrrr

I am an installer at a car audio shop. We like to hardwire bluetooth audio adapters to the factory aux. Your local reputable shop should be able to do it in your bmw no problem. Use this part, as cheaper ones tend to have noise. This has fm mod which you will not be using, but has true analog out that they can hardwire to the back of your aux jack where nothing is seen. At my shop, I charge $100 labor and $100 for the part.

Yes on some occasions i have experienced the same noise.
Its not a cable issue as i have checked grounding, used several cables, and tested with other devices.
It also clears up on its on once you use an app to play music.
I use siriusxm, play music, and pandora..

External Audio Issues on BNIB Nextbit Robin

Going to try and keep this as short as possible. My 2 new Robins arrived tonight. Mine is Midnight. Wifes is Mint. Mine works flawlessly. External Audio Out on the front facing speakers doesnt work on hers. While making voice calls via hangouts and phone I can hear through the earpiece. Mic works. Headphones work. BT AUDIO Out works via external speaker. But when I launch YOUTube or Play Music or anything sound related like ringtones nothing can be heard through the front facing speakers? Is this software related? Or hardware related? I already updated when turning on the phone. I already factory reset the device. I bought the phones from Newegg during the $25 masterpass promo code sale.
Any suggestions?

I flashed the previous firmware and rebooted to a functioning device

So the last firmware worked out then?

External audio out. Are you referring to Bluetooth or when it's plugged in? I can't get my bluetooth to work at all but if plugged in with an external speaker it work just fine.

Stereo audio stopped working with USB-C to audio jack adapter on latest Oreo ROM

Hi,
since updating to MIUI 9.5.6 (Oreo) ROM on my Mix 2 I have been facing some weird issues. I already posted about the lack of fast charging anymore (another thread on the forum - unfortunately it appears I'm the only one experiencing this).
Yesterday, after a long time I decided to plug in my earphones to listen to some music (using the OEM USB-C to audio jack adapter that came with the phone) and realized that the audio was only coming out of one of the earpieces.
I have tried un-plugging/re-plugging, inverting the USB C cable, restarting the phone even a different adapter, but in all cases the audio only comes out of one earpiece.
interestingly with the other adapter (which I have used only twice before) the earpiece that works is switched, so instead of getting audio in the right earpiece with the OEM adapter, when I use the other adapter the audio comes through the left earpiece.
just putting it out there in case someone else experienced any issues since their upgrade or have suggestions on how to fix this issue.
I would rather not try a factory reset … but willing to downgrade to Android 7.x if there is a way to do that without losing all data.

is there anyway to check if the USB-C port on the device is corrupted/messed up?

S20+ Bluetooth Earbuds Call Distortion

Hi all,
I wanted to see if anyone has experienced this same issue and/or has any suggestions on how to fix:
When I use my Master and Dynamic MW07+ earbuds to make phone calls (or even WhatsApp calls) with my S20+, the phone call almost immediately becomes significantly distorted and doesn't go away unless I turn off Bluetooth and turn it back on. The same thing will then happen a few minutes later.
Weirdly, this doesn't happen when I'm listening to music. I can listen for hours without issue.
I previously used these earbuds with a Pixel 2 and didn't have this issue. I also used these earbuds with my wife's iPhone 11 and again there were no issues. Interestingly, I also tried a phone call with my cheap Anker headphones and didn't have any issues with the S20+.
This seems to only happen with my S20+ and specifically with these earbuds (which I already replaced via warranty once). Any ideas what is going on and what to try?
