Hi.
I using a Dragonfly DAC via OTG and when the screen turns off I random interference which is only resolved by switching the screen on.
I have set it to performance mode in the battery settings and allowed Neutron player to be protected but it doesn't make a difference.
My guess is its some sort of cpu throttling down maybe who knows.
Any help on this would be great.

Am I correct that if the screen "sleeps" then the music player turns off even when plugged into headphone jacks. I really hope I just have some setting not enabled or something. Cause on a long road trip, it would be ridiculous to have to have the screen stay on the entire time for music to come out. Android 1.5 music player did not work that way. the screen could sleep all it wanted to, the music would continue.......oh, and I enabled the setting that says "keep screen on when plugged in" and it doesn't seem to work. my screen still turned off thus turning off my music player. also happened after a notification (SMS) was finished processing. screen went off.
no, music is not supposed to turn off when the screen sleeps.
makes sure you do not have automatic task killer or some other similar application that terminates the music.
it's in the ignore list of my task killer app.
Hi guys, I had been playing with my nexus for around a week. Everything are very smooth and overall I'm satisfied with it, but there're 2 things that have been bugging me for a while.
First is the automatic brightness, if I put me device in the well lit area the screen bright up which is normal. But then if I bring it back to dark room it just stay there with the very high brightness and doesn't go down. I need to turn the screen off then on or toggle the auto brightness checkbox to make it back to normal. Is it normal behavior?
Second is the headphone jack, if I plug my phone's headset in (the one with built-in mic and a button to answer the call), the sound from my headset is very weird. It likes you ripped off the vocal and the bass from it, but if I hold the answer button it is normal again until I release it. I tried both headset from Xperia Neo and Nokia C3, it still the same. But this isn't happen with a headphone without mic, it works fine.
So I wanna ask if anyone have the same problems as mine and found a way to fix it.
Thanks for reading.

Automatic brightness is clearly a software issue. I think they only increase the brightness in this setting, never decrease (unless you turn off the screen or change brightness settings). This is done to avoid screen flicker (brightness keeps going up and down when the amount of light falling on the sensor changes). This may happen a lot due to your own shadow.
CyanogenMod roms have an option to Allow brightness to decrease when setting brightness to automatic. This will be the solution to the problem.
The headphones may have different hardware setting (positions of Left / Right / Mic) on the 3.5mm jack. You can try by inserting the jack in the port not full but partially (keep some part in the air). I am talking about the 3 rings you see on the metal jack.
Some have it as Left/Right/Mic and some have it as Mic/Left/Right. Headphones without Mic will only have Left/Right and have last spot empty i.e. only 2 rings.
So try inserting headphone only 2 rings in. That may work.

I have tried CM10 before and it still have the same problem but I didn't dig into the advanced auto brightness option so I missed the "Allow brightness to decrease" setting you said. Now I'm using stock rom so I will take a look into that when I flash CM10 later.
About the headphone jack, you're right. Look like the mic and the ground pin are reverse in my headset and the nexus 7's jack. That's why when I press the button, the mic pin is connected to the ground so I can hear normal sound. Plug it in halfway doesn't work so I think I should find a new headphone without mic.
Anyway, thanks for your answer, it helped me a lot :good:
I have recently purchased a Verizon Galaxy S4 and love it. Initially I planned on loading a custom ROM but now that it is rooted and I have removed much of the bloatware, I realize I don't want to give up most of these Touchwiz features. However, there are two simple issues I have never had with an android device before that are bugging me.
First of all, as I'm sure many of you have noticed, when the battery reaches a certain level, the brightness dims to the lowest level possible and you lose the ability to manipulate the brightness. Generally this happens when my phone has at least a couple hours of battery life remaining. Granted, a bright screen will reduce this time but I'd rather have some usable time than none, as the brightness level reaches a point where the phone is completely unusable if you are exposed to any sunlight at all. I have tried going through the settings as well as overriding the brightness with an app I have called Screen Dim to no avail. Has anyone had success brightening the screen at low battery?
Additionally, every time you plug in a 3.5mm stereo jack into the phone, it drops down the volume and usually forces you to acknowledge a dialog box prior to permitting you to raise the volume. This is a wonderful feature if you are completely oblivious and all you ever use are low impedance headphones. However, I use this almost exclusively on loudspeaker stereos, 90% of the time it is my car stereo while I am driving. Occasionally I use bluetooth headphones but I'm not dumb enough to blast that on full volume so this feature is pointless to me. So now here is one more button I have to read and push while in the act of driving in order to get music playing which is unsafe. Is there any way to circumvent this annoyance?
Anyone else experiencing audio gaps while playing music with screen off?
App doesn't seem to matter (Play Music, N7, ...), Boeffla Sound enabled, Eargasm preset, no saturation prevention, no privacy mode, earphones and speaker boosted and optimised.
Any obvious suspects? Any hints anyone?
NB: Yes, I do use a custom kernel, but I can't tell who's the culprit, so I ask for others experiences to allow to find the cause of it.

Hi
I do not know if this is related but since I installed Omni (coming from latest AOKP); I have issues with my Samsung HS3000 Bluetooth receiver, i use poweramp and I experience a lot of skips when playing music (poweramp is set to automatically turn off the screen after a few seconds); I increased buffer size, poweramp priority, bluetooth priority but the skips remain... Playing thru headphones directly plugged in is ok
Hey guys,
I've been having this issue as well, and I've managed to narrow down what's wrong, but still haven't been able to fix it or find out what's causing it. I'm using stock kernel with the latest nightly on a GS4 i9505.
The issue seems to be that the device is constantly going into Deep Sleep mode. Go into the Performance tab in Settings (unlock Developer Mode first, I think) and have a look at the Time In State data. Right now, for 12h of uptime, my phone is showing 8h of Deep Sleep, despite me using it as GPS and listening to Audiobooks for most of the work day. Even more, it's been happening while I am actually USING the device.
Additionally, it's reporting that my Max CPU speed is 0 MHz, with Min at 486 MHz. Any time I put the slider up to full (or anything, really), it forgets it and goes back down to 0. I've changed Governer and Scheduler, and even used other tweaking apps to control the kernel, but nothing seems to stick.
On the whole, I'd really not mind too much except I listen to audio books while I'm working/driving, and having it skip and stutter because the phone is struggling to process the audio is exceedingly frustrating.
Going to take a closer look around for this, now that I know what the issue is. Putting it up here so you guys can look as well.
Cheers.

My S5 has constant issues with choppy bluetooth to the point were it is unusable in my car. The only way to get around it is to put "daydream" on which IIRC forces the phone to not sleep. Also, I've read it causes bluetooth to not go into low power mode. Is there a way to force this without daydream? Having my screen on while charging is a pain and having to keep my phone plugged in is also a pain.
My phone does this too. Even with the screen on and the car charger plugged the volume cuts in and out. I don't know what the cause of it is. Thought it was just me so I been living with it. Any insight with be appreciated.

I'm going to try cpu tuner and see if keeping my cpu normal when the screen off helps. this requires root. i would really like a solution that does not require my phone to be plugged in.
CPU tuner did not work.
i use to have this problem to, what i did was to change cpu governor manualy to performance and put max frecuency, but the important thing was cpu governor. Also but i'm not sure that i make any diference was to disable Samsung DVFS with xposed, but like i said i never test if this make any diference.
