Hi. I'm using BlackICE ROM and I came across one, major for me, issue. I mean, sound skipping during unlocking device, turning on the screen, opening maps. It happens randomly. Other roms are fine.
I'm using PowerAmp Beta3. But it happens also with MusicMod, GoogleMusic and many others.
Any sollutions yet? I really want to stick with this rom, cause it's the best so far for me.
The only time I have ever experienced similar issues is when I had the screen-off CPU frequency set too low. Increasing it a little stopped the skipping and made the device fast and snappy on wake / unlocking again.
What kernel and governor do you use, and do you use any scripts like Killersloth etc?
I used LordModUE V8 kernel and interactiveX governor. I used setCPU and set CPU to 1.5 ghz
Too bad, that music skipping was happening with screen-on, during normal use. I mean, reading text msgs, browsing. And it happened randomly. On hydrogenmod i haven't experienced anything like this. only on blackice.
Oops, I just hit thanks instead of quote so make sure you do something nice for someone today
Back to your issue... in that case I'm not sure. It shouldn't be happening with screen on that's for sure. Sometimes a full wipe and reflash of the ROM can fix any problems, so that would be my first suggestion. If that doesn't fix it then maybe try some different kernels... like older versions of LordMod or whatever other kernels are popular for CM7 based ROMs (I'm not really familiar myself as I use Sense based ROMs).
Edit to say you could also try Ondemand governor, I find that has best results
Tried many different governors. But the problem was swill there. But the problem is over since i started using unity rom thanx for help! and for thanks ;p
No problem! Glad you got it sorted
I have flashed the franco's kernel with viperx's rom now.
And I find that my phone's battery life does not improve mostly. As I was using ICE COLD JELLY AOKP's rom and with the ncx's kernel before, I find that the battery only fall 1% within 5 min's, but now after i flashed faux's kernel, it falls 1% every minutes!! Therefore, i came back to AOKP's rom and the ncx's kernel, but strangely , it falls 1% in 1~2 mins.. After that, whatever i used the other roms or kernels(such as i tried CM10 ,CM9 ,Android Revolution HD v9.4.1 (Sense 4.1) ), they also come with bad battery life..
One more thing make me confused.
I can't tweak the cpu or alter the governor, although i changed them by using setcpu or other similar apps, when i use cpu spy, I find that they do not change the governor or the mhz..
But when i use the franco Kernel updater, it works! What is the matter of that??
Well third party applications can have compatibility issues. Try flashing another kernel if your battery drains that much, or maybe its something you installed.

Sometimes a full wipe is helpful. However batteries seem to settle after a couple of charge cycles and that's what I would recommend before rushing to conclusions. Switching ROMs with the speed of light won't help you.

Hello, i guess i couldnt post in the actual Kernel or ROM forum because im a new member...
I was wondering if anyone tried or uses the Liquid Smooth JB rom with the KT747 kernel? I was using the liquid smooth rom with the kernel it came with, but the cpu freq kept maxing out even if i set it lower or set on boot, which resulted in horrible battery life for me. Has anyone tried it with kt747? if so, hows battery life? also, does the kt747 have an option to keep it between the min/max and never exceed it?
thank you!
Why don't you just try it. If you don't like it dirty flash the rom again to get the original kernel back. The kernel I use for d2att is imoysens leankernel its the only thing I will ever use. By far the best battery life and stability out of any kernel I used. I have used close to everything. Try it out. Even tho it says it's for tmo its still safe to use.
Give it a try.

Do I just flash the kernel in cwm and then clear cache, dalvik cache and fix permissions and reboot?

i tried this out twice, unfortunately it resulted in a blank screen both times. It worked with another rom tho. Anyone know why it wont work with liquid?
I'm running Liquid JB RC5 with the ktoonsez 10/9/12 release. This has been a very stable combination. I have it at 1.6 ghz, cfq and on demand. I actually got 1 day and 12 hours on my last charge, but that was lower usage than normal with 9% battery left. Hope this helps.
This post only pertains to Jellytime Sosei/BakedBean 4.1.2 and is for users experiencing problems with their A100, yours may not. This thread is not to debate or argue about the kernels, please keep that in mind
Hey guys, I was originally testing these ROMs for pio, and constantly am changing or tweaking things on the ROM to find what suits our A100 best. Pio was building these blind, so he has no way to thoroughly test the ROMs and such things as build.prop mods/tweaks as well as kernels.
Let me start by saying this, I AM IN NO WAY BASHING ANY DEVELOPER FOR THEIR WORK. I AM IN NO WAY BLAMING OR STATING THAT ANY BUGS/FLAWS ARE A DIRECT RESULT OF THEIR WORK. THE THINGS I AM LISTING ARE ISSUES/PROBLEMS/BUGS THAT I HAVE OBSERVED OR ENCOUNTERED, AND ALL BUGS/FLAWS WERE TESTED AGAINST THEIR EQUAL. EXAMPLE, USING THE godmachine81/linuxsociety KERNEL, THAN REPRODUCING THE SAME ENVIRONMENT, I WOULD RUN THE STOCK KERNEL FOR TESTING AND VERIFYING THE ERROR.
Kernel Observation:SODsEveryone, including myself, tend to automatically flash linuxsociety's GodMachine kernel v2.0, as it really is our only option for JellyBean/CM10/AOSP based ROMs. We do have ezTerry's kernel, but it has not "supposedly" been tweaked for 4.1.x systems. Although it is the base for GodMachine kernels. I've never used ezTerry's kernel,but I may test it like I've been testing GodMachine.
Anyways, for this ROM, I have found that the godmachine kernel performs poorly on Sosei ROM. With GodMachine kernel, I had tons of issues with constant BSOD/SOD. (Sleep of Death) The SODs were worse if you left wireless on, and the SODs were completely random, no matter what I did, if the tablet fell aslepp, it SOD'd on me. Using the stock kernel pio packed with the ROM, resolved much of this issue for me. The only time I have SOD on the stock kernel is when Wifi was left on, and the chances of this happening were 99% LESS LIKELY compared to GodMachine. You can combat this, by sacrificing battery life and using an app that's free on the playstore, WakeLock. If you choose to go this route, the "Partial_Wake_Lock" option consumes the least amount of battery while still preventing SOD. None of the 3 options for forcing wireless to stay on worked for stopping SOD.
RANDOM REBOOTS/CRASHING/FREEZINGI myself did not have many issues with random reboots, but I did have some issues with random app "force closes" and freezing to the point where you'd have the almost force close I call it, where you get an option to close or wait for the app. I have not had this issue using the stock kernel, unless related to the next topic...
GPU/VIDEO INSTABILITY/ODDITIESI, as well as a few others, have reported issues with display. Most users have noticed an issue with flashing lines, tearing, and artifacts on the desktop. I have also had issues when play a THD/HD game, for example Modern Combat 3: Fallen Nation HD, where anytime after about 20-30min, the display would become compltely distored, almost like when you were trying to pick up a TV station using rabbit ear antennas, and the game crashes/freezes, but you do not get an option to force close, so you have to use the Navigation bar HOME button to get yourself out of it, than you need to kill the game anyway you want, but if you don't kill it, it will load you back to that distorted, frozen image.
In the GodMachine kernel, the GPU is overclocked as well as being able to overclock your CPU, but you cannot adjust the GPU yourself with any application. Linuxsociety states: "Stable GPU Overclock @ 450mhz (scales from 300 - 450)"
I do not have these issues with video when using the stock kernel, nor do I notice any lack of GPU performance with lack of GPU overclocking.
In my honest opinion, I STRONGLY RECOMMEND the STOCK KERNEL. Yes it is lacking in some features, but it is capable of being overclocked as well if your interested in doing so. Using the interactive governor provides the smoothest performance and still retains some battery savings. Conservative, OnDemand, userspace, and Performance are offered as well. The I/O Scheduler only has NOOP available, but if you do some reading, NOOP is actually recommended for Flash Devices, like ours.
To get back to pio's stock kernel, you can boot into recovery, wipe cache and dalvik, and dirty flash the ROM.
BUILD.PROP EDITINGI cannot even begin to tell you the amount of hours I invested in testing and editing the build.prop to obtain what I find to be the most stable while still possibly enhancing performance/responsiveness and battery life. I will link you to my FINAL build.prop mod for you to download if you'd like. In all reality this consisted of just commenting out several lines in the original build.prop that our A100 did not like. This will also fix issues with the video camera recording if you have them, as well as improve certain app and system performance and functions. I've also had more reliability and just odd **** happen when I use the TCP/IP buffer enhancement code lines so those have been commented out as well to keep WiFi stable. I really see no performance gains with them other than SpeedTest and there is a reason, I am a Networking IT Student, and don't feel like explaining that now in this thread. lol
Download build.prop.sosei__tweaked
Using a FileExplorer with ROOT LEVEL ACCESS (I recommend ESFileExplorer),
Copy build.prop.sosei__tweaked into the /system folder
Rename current build.prop to build.prop.bak
Rename build.prop.sosei__tweaked to build.prop
Reboot into recovery (TWRP or CWM) and wipe dalvik cache & cache, reboot
make sure you wait ten, reboot and wait 5-10 before you start using your tablet
This is all in my observed, hands-on testing and experience, and everyone's results will vary based upon factors such as user setup, apps install, the way a user even uses their tablet etc
I hope this might help/inform some of you guys.
Very nice, thanks for taking the time to put this together for the users. How did that kernel I built for you do?

I hadn't flashed it yet as i had gotten my tablet into a perfect state, for me, with this ROM and stock kernel, lol
The changed prob won't stop sod, but in my theroy should correct the video glitches.
I'll try it soon and let you know.

I'm using/testing this rom along with gm's kernel. I have not had wake SOD issue. It sometime takes a couple if clicks on the power button for it to wake, not sure if this is the issue you're referring to as SOD. Everything seems to work great so far. Netflix, audio, headphone all work well. I have always wanted some aokp flavor on this tab, and now that wish is granted thanks to the awesome work of pio, bb devs and gm.

No, I had sod constantly. But not slow wake up. I get slow wake sometimes on stock, but atleast it will wake.
Everyone's tablet is not the same, some hate the GM kernel.
Mine seems to be one of those, but had I known how smooth and stable the stock kernel was, I prob would have stopped using GM awhile ago, I've had nothing but issues with it, if you've seen any of my old posts over last couple of months.
G2x-temasek CM7 Nightly 11/18/12 Build, Trinity ELP Kernel
Other than a couple of SOD's I haven't had any other issues with the gm kernel. I have since bumped up the minimum speed to 312 Mhz and that has seemed to fix the SOD issue but I still need more time to conclude that. I'm also getting some impressive quadrant scores with it too (3046) and that's with a fully loaded non-tweaked system. The only reason I like the gm kernel is the variety of I/O schedulers and governors...there is absolutely nothing wrong with the stock kernel. I'm still very happy with the JB ROM, I have it set up almost identical to my Samsung Nexus phone which makes it very convenient.
GM SOD Issue Resolved ( For Me)
I can now safely say after 4 days of testing that raising my minimum speed in the GM kernel to 312 Mhz has completely eliminated the SOD issues. I know that every device acts differently but this is working on mine!

I didn't want to do that myself and lose the extra battery juice.
The point is it should be able to UC down to 216 and hold there with no issues.
The stock kernel does it perfectly well with no ill effects.
I have a modified Godmachine kernel that is unreleased and I will be testing it soon.

thanks for the tweaks and info! buti have never encountered a SOD. what happens? it just wont wake up after sleeping? if it happens can you just turn off your tablet by holding the power button or do you have to wait for it to die?

SoD is just a failure to resume from sleep, reset button or hold power will reset it to normal. Some tegra2 devices have it, some don't, even among the same series, like a100s. The best way to combat it is to not sleep, but of course battery sucks.

I can understand not wanting to lose the extra battery juice, lots of what we do is to extend it. I did however undervolt the 315 slot to the same as the 216 (750 mV) so there's no addition battery drain. It's a win-win situation! Let us know how the unreleased version works out, I'm always looking for options.
Can you not dowloadd this from your tab? When I tried it said the download was unsuccessful

Try clearing the data on the 'download manager' in the settings > apps. Then retrying.

G2x-CM7 Nightly 11/18/12 Build, Trinity ELP Kernel
..
Current settings:
Kernel: 3.4.94-QuantumKernel-6/17
Rom: Carbon-kk-nightly-20140617-0002
Freqs range: 384MHz - 1512MHz
Governor: interactiveX
and before this rom and kernel install I was running Liquid smooth and it's kernel, Deathly. I've done several clean flashes of both Roms and just recently did a dirty flash of the QuantumKernel again.
So it's an odd situation, because everything runs great at first. Navigating through settings and everyday apps seem great, the cpu correctly runs at the rate it should. But as soon as I launch Clash of Clans, the phone just drops to 384MHz and everything from then on just crawls. Sometimes it will run fine for 30 seconds or so but then just goes back to 384 on both cores constantly. I've tried installing and using kernel tweaker and overriding some settings. superuser notifications make it seem like there are actual changes being made but then it eventually ignores all tweaks I've made and goes back to running at 384. Had this problem with Liquid smooth last week and posted, no replies. So I found Carbon and a recommended kernel in the designated thread and eventually fell into the same situation. I know there are certain triggers where the GPU overrides the cpu clock speeds, maybe it's something with that since it seems to be triggered from Clash of Clans which is a huge cpu hog. I don't know. Any ideas or suggestions?
Thanks in advance!

I'm not so sure why that happens but I would suggest you try KT747. I've been using his kernel for quite some time now and have no issue with CoC.

Thanks for responding! Just flashed this kernel and so far so good. Though I'm confident it'll stay that way. This kernel is amazing! So many options to consider tweaking but then not mess with in fear I'll break my phone. lol But seriously thanks, this is working great!

If you wanna make some tweaking, look at the scripts/profiles. There is a nice directory full of premade by users (as well as one from KT himself)!
