My issue is noise while charging. Happens in both my cars, completing different setups, using usb dac in 1 car and the 3.5mm in the other.
Really stuck on this, and not sure where to go to get it fixed

I've actually not had much noise while the tablet is charging. But im only using a car charger to charge mine and not a DC-DC since my tablet has constant power. are you using a DC-DC converter?
I've had some noise with music as per my previous postings. I decided to order the Rockford Fosgate BLD Balanced Line Driver which also has a filter in it. My reasoning was I know my DAC was outputting on the smaller side for what my amp could handle so we will see if the filter in conjunction with the voltage increase will make for better sound.
On another note, anyone made progress with backup cameras, preferably using the Febon Grabber?
I'm using a car charger in 1 car, and a pico psu in the other. Doesn't matter what i use, i have tried 2 different usb chargers, multiple cables, a dc dc converter. It doesn't matter, at this point I mm thinking it is my tablet.
Subaru:
Pico psu, uca 202 dac, alpine ktp445u, no head unit
Buick:
Palm usb charger ( best i've ever owned), 3.5mm output, pioneer 740mp, no amp. My note2 works flawlessly in this car.

Not sure if I should just order usb isolator like hifimediy sells or a new dac with one built in. Kinda sick of buying parts

Yea I would be interested to see if that fixes the issue.
Sent from my SM-N900P using Tapatalk
Im guessing it will, a normal ground loop isolator will fix it too, but it shifts the noise into distortion on my tweeters. So that really isn't fixed imho.
Sent from my SCH-I605 using Tapatalk
I also had some problems with ground loop, but i think i've fixed it.
After i have tested the DAC by plugging in a headphone, i noticed that the noise didn't come from the DAC itself, but from the analog part on the output.
I'am using an amplifier in the trunk that is very near my DAC, i just used an usb extension cable from the usb hub (near the nexus) to my amplifier in the trunk.
then i only use an 15 cm rca cable to connect the dac to the amp (high quality rca cable) and my noise is completely gone.
I just kept the analog part as short as possible and it worked for me.

I'm using a $15 power inverter and the stock Asus wall wart charger to power the tablet, joycon, hub, usb dac. No ground loop noise. :good:

I tried the drok converter, that wasn't the problem. The problem is in my lte nexus 7.
I don't remember noise when I had the wifi only, so it is probably something to do with the radio and the charging circuit, or I just happen to get a subpar charging circuit. Either way my noise is originating in the nexus internal circuitry.

Is any one using a HD tuner for their installs. Specifically the directedhd tuner? I saw a 2012 installation with the tuner but nothing of the 2013 version. I have one laying around.
Anyone looking for a cheap dac? I'm going to sell my uca202. It works great, sounds good, just want to try something different. Thinking 20.00 shipped, only 2 months old

Does anyone have issues with there tablet randomly restarting? I don't get it to often but just enough to be frustrating. I running Timur's kernel but don't think it is related to that. I am guessing it is the cheap power supply I am running it off of at the moment. Anyone run into this and figure out a fix?

Shouldn't be. I live in Minnesota and it's not to warm out yet. This morning it restarted after a minute or 2 of driving and it was only maybe 60 out.
What extras or what rom are you running?

Btw, figured out how to program my m3-atx the other day. It now shuts down after 7 seconds, i couldn't get it to go shorter than that, it allows my amp to turn off before my dac so no more popping on start or shutdown!
Just need my usb filter and i can finally mount everything. Hopefully it shows up before the weekend.
Last thing to do will be to program tasker and a few nfc tags.

Have you tried using a different charger or tried charging through your PC to eliminate potential problems with the plug and cable? Just a thought.

Try to jiggle the cable in certain directions such as up down left right and see if it starts to charge. If it doesn't, return the sucker.

I have found the N7 is picky with cables' the default one that comes with it works fine but doesn't seem to want to charge through my car charger.
My epic4g cable doesn't work and neither do any of my other USB cables.
Same with the charger, it has to have a dedicated live connection and no USB splitters with multiple ports.
I need like a good 4-5' USB cable to use tablet comfortably while charging.

I am now having similar problem on 16gig. It will not charge from the power adapter at all, but will charge from a PC using same cable.
Same behavior on my alternate cable that I use for phone.

My car charger doesn't work either but my computer/tv/printer/tivo/wall/everything else works just fine... it must be a voltage issue with the car charger.
I remember reading that the charging issue some of you guys r having is a confirmed hardware problem, due to poor quality control. Asus was in such a rush to get the first few batches out that certain faults made it into a select number of batches. Other people who have had this hardware problem either could only use the Asus adapter, or that might not even work. You should try to get it replaced by your seller. I'll post the source in the morning if everyone's too lazy to Google.
Cheers
possible fix
I've read on other forums that it is the usb port. I my experience it is a intermittent connectivity or the wall wort isn't putting out enough amps. I bought an iGo Green for the iPad, put the tablet in Airplane mode and it will work fine while using it. Last night I shut it all the way down, let it charge overnight and woke up with a full battery.
Seems like only high output chargers work. All my 2.1A chargers work with Nexus 7, but lower output ones do not charge even when Nexus 7 says it's charging.

My 8GB arrived Monday , 1/2 charged pluged in to the 2A charger it says its charging but the battery just drops. Turned off and left overnight and its still no more than 20% charged.
I need to find an app that shows charging
check output of charger, check cables, check charge on phone vs tab then send back to Google for a replacement grrrr
I have the same problem, how do I fix? I have the 16 gb version.
The N7 seems to be having a lot of problems with charging. A couple times when my battery has been completely dead, I have had a tough time getting it to begin the charging process. One time I watched it begin to charge, then boot up, stay on for about 20 seconds, turn off, and then not charge. I have no idea what's going on. I always eventually get it to work, but something doesn't seem right.
Remedy
Google Play telephone support had be factory reset my Nexus 7 8GB. After the reset, the battery began charging. A major nuisance having to redownload everything, but it does work. Good luck

I was wondering if anyone knows if a charger like this even exists.
I'm looking for one that can charge multiple USB devices both 1 amp and 2 amp (like the N7) without umm...sharing amps (for lack of a better phrase I guess).
From what I'm seeing there are a lot of these multiple USB chargers, BUT...they only support up to a combination of 2 amps. So if I plug in 2 cell phones and 2 tablets (of which both tablets are 2 amp), basically nothing will charge anytime soon.
Anyway, if anyone knows of one, that would be cool.
I was at walgreens the other day and I saw a charger with two outputs, top one being 2.1 amps and the bottom being 1.

That's the problem I'm finding. The multi port chargers only support *up to* 2.1 amps, so it really isn't very useful if you have 2 N7's for example.

Hello, I've built a USB Y-Cable myself, I plugged a USB stick in without powering it... So the nexus alone wasn't capable of powering it... I plugged the other site into the wall socket... The nexus crashed somehow and it showed a black screen... I immediately plugged it out and turned the nexus on. Still working and charging also works... Hopefully nothing was damaged. Does anybody know what went wrong?
Was there any kind of resistor preventing from pushing current back into the nexus thru the cable? Because that could've been what happened and if it was , you might want to be careful not to fry it! Why going thru all that trouble instead , If you want to power a HDD you might want to get a USB hub for that. There like 5 bucks on eBay.

No I dont think there was any resistor... It still works, what could be broken? Yeah I've got tons of them at home but lazy me...
OTG cables are supposed to be a bit special. A stick should be no problem to power from the Nexus. Even portable harddrives work. If the otg cable is correct the Nexus usb port should be put in host mode which then feed your stick with power. If it does not power the stick, host mode is probably not active and it probably will not work anyway. The kernel needs to be patched to allow host mode and possibility to charge at the same time. There is a patched kernel for Nexus 7 for Cm10. I have looked for this myself for my Nexus 10 since I want to power a portable harddrive and charge from my car charge.

Hello. Just a few days into my Nexus 4 experience with Straight Talk. Loving it!
However, I do have one problem. Whenever I plug my phone into the car stereo via cable (headphone out to aux. in), I get a lot of shrilly interference. It's a mixture of a hum and high pitched noise. I didn't have this problem when listening to music from my Milestone X. My friend doesn't have the same problem when plugging in his iPhone. Just my Nexus 4. I currently use both PowerAmp and Google Play Music players.
Any ideas?
I'm running stock 4.2.1, rooted and unlocked.
Regards.
No one else experiencing the same issue?
I had no issues with mine, maybe you should try another adapter and see if you run into the same issue.

I'm just using a cord that plugs into my headphone jack and into the AUX of the radio. There's no interference when I use my old phone or my friend uses his iPhone. It's just with my N4.
You have a ground loop that is causing the audio garbage. Is your phone charging at this same time? If so, try disconnecting it from the charger.
Ground loops can be lifted in a number of ways depending on where the problem lies. If it is charger related, getting an isolated power supply to charge your phone will be the best fix. I use a 2 amp model from DaqStuff.
If it happens without the charger, the simplest fix is an audio transformer coupled audio cable designed specifically for this purpose.
Maybe this is a dumb question...but I've been looking at getting an external DAC for some time now. But I've got some questions, specific to the moto x pure.
1.) Does anyone have anything to say about the quality of the Moto X P's internal DAC? I'm getting a 128GB microSD so I can listen to my FLAC collection in my car, (New car, got the 9 speaker high quality system :3 )
2.) Does an external DAC charge the phone since it is USB? Reason I am asking is I DO NOT WANT one that charges the phone all the time. I like to keep my batteries strong by not charging them but when I need to.
3.) I know Android 5.0 added USB Audio...but does anyone know if the Moto X P supports USB Audio? If so... is there anything I need to do setting wise for it to work? Or will the phone "detect" the DAC?
4.) On a side note...are their any music players that any of you would say is better/the best for using FLAC?
Thanks guys.
After I grab a DAC and get it all hooked up I will post a mini review of the experience as well for anyone else who wants to max out their moto.
Normally usb dacs drain battery, or use their internal battery of the dac to reduce drain from phone. The only dac I know which can charges the phone is the fiio e18.

The hifi usb cable should not charge the phone, but it's very expensive. Maybe there are cheaper versions. (Can take a look in the ifi Gemeni)
you can ask the ifi support to be sure, they are really quick and competent.
But with the usb hub I'm not sure, maybe one of your friends have one. I don't know if they supply power to the host device or not.
