[FIX] Music Playback Crackling/Clicking Issue

First of all, id like to thank Gokhanmoral and Simone for the support... Special mention to TotallydubbedHD and Studiominal for the great contribution and to all who tested and helped...
The idea was first toasted by Gokhanmoral via PM, that it has something to do with idle status and not with hot-plug issue. Then Simone201 also posted about this on "official sound quality thread" which leads me to test dif configurations and combos... Then i came up with this little Fix:
1. You have to be rooted of course...
2. Flash Siyah Kernel (Sorry for this, since i only tested it with Siyah 1.3.3b and 1.3.7b)
3. Download & Install exTweak by Darek.Xan from the Playstore (Free one will do)
4. Grant Superuser
5. Navigate through the CPU Tab and set the CPU idle mode to; IDLE ONLY
6. Reboot
It was first tested with Siyah kernel 1.3.3b and was confirmed by Studiominal thru his "sinewave" that there were no crackling found in the graph. It has also been confirmed that it also work with 1.3.7b... I cant comment on other kernel since the test was thoroughly done with Siyah...
Hope this help... ENJOY!!!

Evidence provided
It seems like something in IDLE + LPA, AFTR + LPA, AFTR only causes the audio codec to suffer from power shortage that leads to turning the codec on and off really fast.
And.. to clarify, I only changed the cpu idle mode to IDLE ONLY, and disabled all the audio options that come pre-enabled both to see whether the idle mode is the culprit and wait for the new Voodoo Sound.

Thanks for the graph Pal...

Thanks guys for sticking with this and finding the problem.

Now that the culprit has become more obvious(likely the DAC being not able to perform properly with that low current set by stock setting), we'll see more developers here digging down the kernel with power profiles

Changed the setting to see what the impact on battery life is, i am not sure what lpe and aftr does, so not sure what effect we will see. Probably someone with more insight could clear this up...

but this is not the solution, it is a crutch

more of a temporary fix...

Iv never come across this problem but I use player pro and have never tried using the stock player, also, I use it with the lock screen player on which keeps a partial wake lock, perhaps this is what stops me having the problem.
I know the phone is awake because my nfc works when screen is off and player is playing.

Does this only effect Siyah Kernel?
Cause if its across the board on all current kernel sources what would be the solution to any any other kernel besides Siyah and using exTweak? A Script?
Also, I get choppy audio on almost all games and the same clicks on other audio related apps, could this be the same issue? This behavior almost sounds like latency problems of a low default audio pre-buffer...

According to Andreilux
LPA causes the CPU to be clock-gated, meaning the clock to the CPU is cut-off. I imagine that when power resumes, or actually is cut, it either causes a drop or spike in the power supply which interferes with the DAC and amplifier. This is inherently a hardware problem; they could have prevented it if they had put adequate filters on the PMIC, or whatever is in-between them which causes the interference. LPA is idiotically power-efficient and turning it off can cause worse idle battery life, so turning it off it in my opinion not a very viable option. The only options to fix it are already available to everybody already through changing of the idle states. If there's something to be done on the DAC-level itself, I don't know. CPU noise is a pain in the ass and wide-spread (Think about on-board sound on computers) and sadly there's not much to do about it if it's badly designed.

See where it starts going down in 25mV intervals, do that all the way to the bottom (the app there is Kernel Tuner). The top two frequencies can be dropped by 25, but from there and any lower on the top two and you'll get an undervolt forced reboot. Some of the low end freqs might be able to go a bit lower than what my scale gives, you'll just have to test yourself since every phone is different in the undervolt department. And do not set it to activate on boot until you've pushed your phone a bit and know those voltages work. It is possible to undervolt brick a phone forcing you to do a factory reset to remove the saved undervolt values (or a full rom install if you save bad undervolt settings in an init.d script).

Guessing at the rom....probably PAC 4.4, but like Techno said, that really doesn't matter. And those are lowered.

[Q] AHD custom kernel and settings

Hey guys and gals,
I've been searching AHD forums for a while now and I could find zip zero result on custom kernels even though I'm sure that I've read people write about Aaargh kernel before... [his user name's spelling ain't really helping either....]
So here I ask: where can I find it (or other custom kernels?), read what people have to say about it and what results are to be expected?
Lastly, what are you guys settings? I mean what voltages are you guys using? I understand that no phone/cpu reacts the same to undervolting, but I'd like to get an idea on how low I could expect to go...
I'm not really after overclocking as I find my AHD's performances acceptable at stock values; I'm just after better battery performance really.
Thanks in advance for your replies; I will be offline for the next few days, but will sure give thanks hits upon my return.
Cheers

Ok thanks for the link.
I wasn't searching at the right place and on the wrong device forum...
So in an attempt to make this thread useful, I'd ask again: anybody wants to share their experience with that kernel on AHD?
I mean other than getting a phone that can basically now running up to 2GHz and down to 96 MHz, what did you get from it?
- How (and how much) undervolting did you do?;
- Any noticeable and verifiable battery saving doing so?;
- Any before/after benchmark results to share?
- any observations, bugs or just general opinion on the subject?
Personally, I've noticed once or twice that the phone had a hard time waking up when I used 144MHz (forgot the exact value) as min cpu frequency (no undervolting). The screen would not turn on with either volume rocker or power button...it only did after a lot of insisting... And that was just within a couple hours of testing.
I've since reverted to CM11 kernel since I was eager to find out if a semi-dirty (no stock rom reflashing first) nand backup restore would switch the kernel back. And it did, but then I've also re-installed CM11-M8 for other reason/issues... (that too brought back CM kernel - at least that's what the "about phone" is giving).
Anyhow, the debate is open on the usefulness of that custom kernel. If no one dare to pitch in here, I'll just ask a moderator to delete the thread...
But I'm still eager to find out about how to undervolt as I always did on my Defy.
Cheers

I'm also curious about any battery-saving benefits that can be gained with Kernel adjustments; especially when screen is on (since I drive a lot with the screen on all the time). I have no interest in Overclocking, and would rather have the phone last as long as possible and still be useable.
Currently using arrrghhh's kernel (May 23 version) with:
1. Min 384000 (default)
2. Max 1458000
3. Scheduler: deadline
4. Governor: smartassV2
5. App: Trickster MOD
Also, the only way I've been successful in changing anything is by using the Trickster MOD app. Between CarbonROM and the CM11 (epinter) that I'm using now, I've never been able to get the kernel changes to stick. Didn't matter whether I used the default kernel or arrrghhh's, any modifications in my settings always reverted back at some later time.
Trickster MOD uses some workarounds to get it to stay, and I haven't had any issues since.

No. "CLICK TO SHOW CONTENT", then download the latest version (May 23) that doesn't use SaberMod. Only reason I was using that was because arrrghhh mentioned that SaberMod thing was experimental and may have issues. So I just chose the safe option.

Since you're a new xda member, I'll remind you that there is a button specially made to thank people... Look at the bottom left of the post useful to you...
As far as the undervolting goes, I found that the free app called "Trickster Mod" can do voltage changes. So I've done a bit more testing with the May 23rd anykernel and my results weren't that great....
First, I went too aggressively and try to lower the voltage by 150mV for every cpu frequency and that made the phone reboot as soon I applied it. I mention this because the lesson here is to
*** NEVER SET THE "apply settings on boot" OPTION UNTIL YOU ARE ABSOLUTELY SURE THAT YOUR NUMBERS WORK FINE. ***
Not doing so might make your phone unbootable and you might not even be able to boot to recovery/bootloader mode to revert kernel/settings....
Ok, that being said and since I'm after battery saving while the phone is in use*, I then went ahead and lowered by a more reasonable 50mV for each frequency (the app let's us move by 25mV steps). That 'worked' fine and I've experienced no sudden reboot. BUT, after some time (30 minutes), I've noticed some slowdowns and I've also had issues with an app that stopped creating video thumbnails. So all in all, that called for the end of my testing and I restore my CM11-M8 nandroid as I'm not going to live with such drawbacks for some slight (still yet to be proven) battery improvements.
So no custom kernel for me afterall.
.... Should this thread be deleted???
You guys tell me.

*: hence I see no point of lowering the minimum cpu frequency: my phone does not take excessive power when on iddle, it deepsleeps fine and I use airplane mode at night..
*': some have argued that increasing the max cpu frequency allows the phone to complete tasks faster and return to a low power state sooner resulting in a lower overall battery use. I have my doubts on this and I'm pretty sure that it depends on what kind of task the phone is mainly doing. Anyhow, this is not something worth testing at this time... My AHD does its job just fine at the stock max cpu f.

I've been experimenting with dynamic stune boost from @joshuous with good results. Seems to be some improvement in battery. If you want to try it, I've put all the necessary settings into one place in the latest version of EX Kernel Manager (version 3.56 and later).
Go to the CPU screen and select "Boost Settings" to open the Boost Settings screen
-Disable MSM Touchboost
-Change Dynamic stune boost to 15 (or somewhere between 10 and 20)
-Set all Input boost frequencies to 0 MHz (i.e. disabled)
-Change Input boost milliseconds to 1500 (might be unecessary, feel free to experiment)

I can't believe you stuck with the m9 that long. I still like HTC, but I'm not getting the U12+ this year. There are a lot more users on the OnePlus and Pixel forums these days.

I've just updated EX Kernel Manager to support the OnePlus 6. EXKM version 3.51 adds speaker, headphone, earpiece and mice gain adjustments, HBM, CPU frequency adjustment and kernel downloads for this phone
https://play.google.com/store/apps/details?id=flar2.exkernelmanager
And, I also updated High Brightness Mode to support the OnePlus 6. This phone does not automatically use high brightness mode, it's now a hidden hardware setting. I've updated High Brightness Mode app to support the OnePlus 6. You will need root to unlock brightness about 10% higher than the max stock setting. You can use this app to enable HBM automatically in the sun, using a widget or with quick settings.

Question What does the Galaxy App Booster in Good Guardians really do behind the scenes?

Has anyone been able to figure this out?
What does this app do to "boost" performance?

Use a lot of cpu cycles, heat up the phone... that's about it.
Useful for burn in when you first get the phone, you know help get the cpu heatsink properly seated
My stock 10+ OS load is over a year old, still fast and stable without using that app.
SD Maid, using the old Device Care cleaner (firewall blocked) and clearing the system cache occasionally is all I do.

It seems that it may be compiling the app for your target device.

This might shed some light...TL;DR of TL;DR: not much if you're patient, the OS would do the same things in a few days.
“Magic Trick” of Galaxy App Booster
I happened to try an app called Galaxy App Booster that is a part of Galaxy Labs released by Samsung. It claims that it can optimize all apps on device and boost the overall performance by 5% to 15%…

Interesting. Perhaps mine was already optimized although I ran it the first or second day after reloading.
On my 10+/Pie I didn't notice any difference the couple times after I ran it.
It's usefulness seems limited to being a hand warmer in the winter.
I have also noticed that turning on any power management tends to create issues and not help battery life. Problem apps are best addressed directly. About all I do otherwise is close apps when done with them.
In the end Android Pie on this device manages its self very well (after heavy reconfiguration).
My current OS load has seen heavy usage but doesn't show it... I'm impressed to the point where a reload seems like it be a waste of time even after over a year.

Snake oil?

It actually runs the shell command in the picture below to compile the apps in speed-profile mode.

You can also manually compile the apps you need via adb:
adb shell cmd package compile -m <MODE> -f <PACKAGE>
In fact, I think that using the speed mode will have better performance than the speed-profile mode, but it will take up more storage space.
More about the compile mode, see:

I guess it should be similar to the Clear dalvik-cache option in the previous version of recovery, which will "undo" the optimization of all apps so that the apps can be re-optimized after reboot, just like a FOTA did.
