Issue is not that it doesn't work once set up - it takes like 90 seconds to install drivers and hangs, giving you a message that Viper has stopped working before it finally installs. No other kernel I have seen does this.

[MENTION=3795148]neobuddy89[/MENTION] I have been meaning to ask, does your kernel (probably any kernel with an included ramdisk) edit the audio_policy.conf of a ROM when you flash it? Or is that something only the ROM touches? I'm having a hard time figuring out what's doing what throughout testing and at this point I've decided just to ask, as I have to go out to my car to connect to my auxiliary port after every flash to test - very difficult with my daughter here at the moment. I've been testing some other things to get Viper working on multiple ROMs and I have figured a lot out, but I am unclear on whether I need to make these changes anytime I flash a kernel, only when I flash a kernel that does not use the built in ramdisk, or only when I update ROMs. If you happen to know off hand, I would greatly appreciate it - if not, no worries, I will test it late tonight when I can go in and out freely.

Edit: yeah, tested and Hydra installs an audio_policy.conf that is not friendly to Viper4Android. In this post I compared two normal N6 audio_policy.confs from gits to one in which V4A works totally, auxiliary connectivity and Chromecast and all: http://xdaforums.com/showpost.php?p=59597521&postcount=17579

Odd, I get the hang on pretty much all of them, but it always completes without any error popups. I figured the hang had to do with 5.1 :confused:
[Nexus 6  Original Android Development] wrongway213:
Nope, Hydra always had that issue, been using it since the first 5.0 release.
[Nexus 6  Original Android Development] jiv101:
Today I flashed viper on Hydra and euphoria rom, after viper working I plugged in headphones then lost all sound
[Nexus 6  Original Android Development] neobuddy89:
I don't understand what v4a is trying to do.

However, hydra's audio_policy hack is scheduled to be removed in next build.. doesn't seem to work on 5.1.
[Nexus 6  Original Android Development] x0nar:
Hi Everything was working fine until today. Today I paired my Android Wear and since then the device is not going into deepsleep. Please help.

I'm currently on 11/3 Hydra Bliss 2.1
[Nexus 6  Original Android Development] otisman:
Try wiping cache and data in recovery and reboot
[Nexus 6  Original Android Development] x0nar:
Tried that but still getting it.
[Nexus 6  Original Android Development] wrongway213:
Normally it is forced to play through the phone speakers when V4A is plugged into an auxiliary port, instead of playing through the speakers I plugged it into. That modified audio_policy makes it play through the speakers you are plugged into normally instead. However, every time I upgrade Hydra. I have to flash V4A again, and it hangs and tries to close V4A before finally installs drivers. Once I'm rebooted with drivers installed, I see reflashing V4A again had changed my audio_policy.conf back to one that does not allow V4A to process through external speakers plugged into the auxiliary port.
[Nexus 6  Original Android Development] neobuddy89:
New nightly build available:

Hydra_v2.0-[03-22]-[17-35]

* Remove system audio blob modification (Reflash ROM + gapps + this build)

* Updated kernel audio driver

* SELinux tweaks for SuperSu.

I have tested V4A on above build using Play Music and Reflashed ROM.

It works but I will stick to PowerAmp's FX. :)

You are awesome! Thanks so much man! 100% fixed all V4A issues. Glad to be back on Hydra.

Hi there. I try to change the hotplug but I can't. I get this massage that you can see in the screenshot.

Have try to find a answer but didn't find anything.

Something that I'm doing wrong?

Here's a logcat.

Thanks for taking care of the issue with Viper, working great!
[Nexus 6  Original Android Development] neobuddy89:
It's synapse issue. Try exiting app by swiping out and then reopening synapse for changing hotplug.

Hey man, I've tried your two latest builds and am getting no UCI support detected. I've tried flashing UKM but with no luck. Any ideas?

Are there issues with this kernel and cm12? Every time I install it either bootloops or FC's stuff then reboots.
[Nexus 6  Original Android Development] jiv101:
I take it your on the newest Hydra kernel build, which isn't compatible with cm12 cause cm12.1 isn't out yet
[Nexus 6  Original Android Development] kevkid:
Correct, I'm using the latest, should I use the last v1 build?
[Nexus 6  Original Android Development] jiv101:
If you're on 5.0.2 you need to be using Hydra v1.0 [03-14]_[00-21]
[Nexus 6  Original Android Development] grv00711:
anybody using this with chroma 3/25 build ?
[Nexus 6  Original Android Development] kevkid:
Hrmm it actually still gave me problems, it goes to boot loop. I have tried completely wiping the system +data and still causes issues. To note I had multirom installed but am not injecting it to either ROM or kernel
[Nexus 6  Original Android Development] bleached45:
Is anybody running this on a 5.0.2 ROM (Blisspop here) with the 5.1 bootloader and radio? The kernel worked great until I updated those 2, now the boot animation plays then the screen goes black and display doesn't turn back on (but I can feel vibrations). I reflashed the ROM and gapps, and it booted fine. Then I flashed Hydra again and it did the same thing. I doubt the 5.1 kernel would boot the ROM, but I find it strange that the bootloader or radio would make that big of a difference. haha. Thanks.
[Nexus 6  Original Android Development] SaZh047:
Hi, I'm having a weird issue... Like I saw on previous post, my device would just freeze...

I'm running the latest Benzo ROM.

It happened: using camera app, Snapchat, g+ and chrome...

I really don't know why tho... Anyone has a fix for this?

Ty
[Nexus 6  Original Android Development] neobuddy89:
Let me download Benzo and check.

Tested on Chroma/Euphoria, works fine.
[Nexus 6  Original Android Development] wrongway213:
Look in the thread before you do.. your kernel is not the inline kernel for Benzo but it's used by a LOT of us, goes perfectly with that ROM. I can't replicate these issues and have not seen any other mention of them - may wanna ask around in the Benzo thread first (user with issue, not you)
[Nexus 6  Original Android Development] DutchDogg54:
Just FYI - I just had a freeze tonight after opening Google + while running latest benzo & hydra, so I can confirm something's up.
[Nexus 6  Original Android Development] wrongway213:
Well I stand corrected. No issues here, odd as so many of us use Hydra and its not being mentioned there
[Nexus 6  Original Android Development] SaZh047:
Thank you so much!!

I really LOVE benzo and your kerel! Bit its unusable with these freezes...

Hope you find something... I tweaked the kernel according to someone in the Benzo ROM BTW...

---------- Post added at 01:23 PM ---------- Previous post was at 01:20 PM ----------

Do you run any specific apps? Maybe we have something in common that make our phone freeze...

Really they find something...

I'm currently running vindicator kernel and don't have the freezing issue... So I'm quite sure it comes from Hydra :(
[Nexus 6  Original Android Development] sgloki77:
I'm having a couple freezes a day too with chrome beta browser and swipepad, google now is irresponsive sometimes

Benzo user with Hydra here. Only had one freeze and that was the first time I went to take a photo with Google Camera., once I tapped the shutter button the device froze for about 20-30 seconds. Been purring like a happy kitten ever since though.

[Nexus 6  Original Android Development] neobuddy89:
I will download ROM and check. Tested on CM12, works fine.
[Nexus 6  Original Android Development] wrongway213:
Thanks, will try later on and report back when I have a chance to flash again later in the day.

Edit: I see xenx had already beat me to it, seems that's the issue.
[Nexus 6  Original Android Development] cavalier11:
No issues here at all. Kernel is running great and very snappy. All the options offered by the Synapse app are a great addition. I can't say much about the battery life being that I just flashed the kernel last night, but so far the battery life has been good as well. No unusual draining and standby has been good. BTW, I'm running stock 5.0.1. Thanks :good:
[Nexus 6  Original Android Development] xenx:
I was specifically using resurrection remix 5.3.6. When I had updated to 5.3.6, I forgot to reinstall SuperSU. It was using the built in superuser for CM12. For testing, I formatted and installed the latest CM12. With the built in superuser, it gave the same error. After installing SuperSU, it worked. I restored the backup of RR 5.3.6 and installed SuperSU and it's working.
[Nexus 6  Original Android Development] chipstien:
I didn't realize that synapse was working on Nexus 6 yet?
[Nexus 6  Original Android Development] wrongway213:
Odd - I have been using SuperSu 2.46 all along on Dirty Unicorns and getting that error.
[Nexus 6  Original Android Development] pantmunu:

[Nexus 6  Original Android Development] xenx:
Incidentally, Synapse stopped responding on me a few minutes ago. Now, I get the error message on open again.
[Nexus 6  Original Android Development] Circaflex:
been running the first release for almost 24 hours now, very nice kernel and very smooth, deep sleeps like a baby. I enjoy all of the tweaking possibilities offered. thanks neo
[Nexus 6  Original Android Development] wrongway213:
OK, not happy you're having issues, but good to know I'm not the only one, lol. I suppose we wait and see what neobuddy89's instructions are, as apparently your results so far have been the same as mine.
[Nexus 6  Original Android Development] Circaflex:
in your supersu settings do you have enable su on boot checked? I noticed a lot of my superuser issues went away with all kernel apps after selecting that option
[Nexus 6  Original Android Development] wrongway213:
Lifesaver! Normally ALWAYS checked - dunno what happened during TiBu/last ROM flash/SuperSU update, but that was unchecked... whether or not that was my issue, glad to have that set right as I'm sure it'll cause/has quite possibly been causing me issues.. thanks man

---------- Post added at 08:05 PM ---------- Previous post was at 07:15 PM ----------

Things have only gotten way more bizarre since following another suggestion of enabling SuperSU on boot. Now I get the same error... and I am in enforcing and Xposed is running and the modules are working. Not a clue what is going on, gonna bring that to another thread when I figure out what even is happening and if I can recreate - that should be impossible I thought. I did set permissive in Synapse, so I dunno if that is relevant or not as it is not appearing to be working.

Regardless, back on topic, when I run the terminal command I get the following:

mkdir failed for /tmp, File exists

ln: /sbin/uci: File exists

Checked in ES and the file is indeed there. let me know if anything I can do to help diagnose - dunno if a logcat, dmesg, kmesg, etc will help for this particular issue as I genuinely have no clue what it is.
[Nexus 6  Original Android Development] xenx:
In my case I have Busybox Pro. It was set to wipe Busybox from /sbin on boot, as it was set to install Busybox to /system/xbin. I have unchecked that option and so far, Synapse is working.
[Nexus 6  Original Android Development] wrongway213:
Busybox Pro.. that would explain it, forgot to uninstall.
[Nexus 6  Original Android Development] Circaflex:
so busybox needs to be in sbin rather than sxbin?
[Nexus 6  Original Android Development] neobuddy89:
Hydra kernel will auto install busybox in system/xbin

Please do not install external busybox.

[Nexus 6  Original Android Development] boynamedstacy:
I flashed the latest build from the link in the op and it forced encryption!? I see where it says this kernel has that disabled. So that's wrong?
[Nexus 6  Original Android Development] jiv101:
Sure you weren't before the flash, cause I'm decrypted still
[Nexus 6  Original Android Development] wrongway213:
This kernel is just floatin, thanks neo! Best performance I've seen out of my phone yet I think.
[Nexus 6  Original Android Development] michmeister:
I just started using this kernel. I have a question. Can I just use as is? I noticed only one core is online a lot. Is that normal? Phone definitely smoother and faster.
[Nexus 6  Original Android Development] wrongway213:
As is is nice, I tweak very few things on this kernel. The write-up in the Benzo thread is great if you want insane battery life, but I get amazing battery and smother just using defaults. Personal preferences: fiops scheduler, turn off gentle fair sleepers, enable USB fast charge, use FB notifiers, DT2W. Other than that all defaults here.
[Nexus 6  Original Android Development] Skripka:
Normal for this kernel. Franco (among others) I believe use the more recent hotplug logic that Google defaults to in the 5.1 stock images of not offlining any cores.
[Nexus 6  Original Android Development] michmeister:
Thanks for suggestions I'll give them a try:)
[Nexus 6  Original Android Development] boynamedstacy:
I'm positive. I've made it a point only to decrypt once, back when the phone first came out and haven't gone through the encryption boot since today. Pretty bummed
[Nexus 6  Original Android Development] michmeister:
I applied settings and restarted synapse after saving and I got popup saying no UCI support detected.
[Nexus 6  Original Android Development] jiv101:
Did you create a backup in twrp?
[Nexus 6  Original Android Development] boynamedstacy:
I did. Resorting backup will not decrypt unfortunately. Only a factory reset/wipe userdata can decrypt at this point.
[Nexus 6  Original Android Development] neobuddy89:
Restarted synapse? If any1 get No UCI support, pls swipe out synapse from recents and open again. Seems synapse issue on some ROMs.
[Nexus 6  Original Android Development] jiv101:
Wow that's weird
[Nexus 6  Original Android Development] neobuddy89:
I am sure it's not kernel.. Check attached pic there is no forceencrypt in our fstab. View attachment 3233723
[Nexus 6  Original Android Development] boynamedstacy:
It appears I flashed the 2/27 build from the link in the op. That one I assume is force encrypt
[Nexus 6  Original Android Development] neobuddy89:
You can keep all cores online by just setting min cpus online = 4 via Synapse. [emoji106] though i dont think that's required..
[Nexus 6  Original Android Development] neobuddy89:
The very first build for 5.0.2 was forceencrypt.
[Nexus 6  Original Android Development] boynamedstacy:
Well I'm an idiot then. Thanks

Now that the Kexec Hardboot patch has been released by Tassadar, could you add it to your kernel ?

[Nexus 6  Original Android Development] neopolotin75:
Question peeps.....

This is my 1st time using this kernel(heard the hype wanted to see) and so far its pretty awesome. I downloaded the synapse app and noticed the color corrections stuff like saturation, contrast and values start in the 250 range but every other app and reference info I could find has them starting at 120 or there abouts. What setting is everyone using or how do I convert 250 to the 126 that's being used elsewhere as a reference? Thx!
[Nexus 6  Original Android Development] SaZh047:
Same here ! I was having freeze and the previous build, and it seems to be gone now!

So happy! This kernel is dope :D

Ty :)
[Nexus 6  Original Android Development] papikev:
I hate to break up the positivity, but I did have a reboot this morning. It may have been a rogue one as a watchdog reboot, but nonetheless here are some details on my set up:

Rom: Chroma's latest

Kernel: latest Hydra

Layer installed: yes.

UV: stock settings

OC: stock settings

Xposed modules: absolutely not

The only settings I tweaked are:

Scheduler: Fiops

Read ahead: 1024

Congestion control: Westwood

Sound: loud

DT2W: enabled

Hotplug: Bricked

All other settings are stock. What I was doing when it froze and rebooted was that I was inside ES file explorer. When I finished, I exited by pressing nav bar back several times and that is when it froze and rebooted. Again, this may have been a random reboot as all others seem not to have reported this behavior on the latest build. I grabbed a dmesg and pstore log of which is attached. No doubt that I will keep this as my daily as I dig it. Thanks man.
[Nexus 6  Original Android Development] neobuddy89:
The error seems to be initiated in android binder which is extensively used by userspace to allocate memory and error doesn't make sense to me since tracing of mem allocation caused error.

I have cleaned up binder ioctl and synced up with 4.0 and CAF upstream in below build, please share logs if issue persist. I need to test with your settings - definitely didn't had any issue with stock settings. (I suspect FIOPs)

@all:

Before installing below build, I would recommend to flash your ROM first.

The system partition modification done by previous builds is now removed since we can now prevent freq scaling by 5.1 stock mpdecision and stock power hal.

So, previously added custom power hal and mpdecision binary are now removed from installation zip.

Hydra_v2.0-[03-30]-[00-18]

* Added MultiROM. (Get compatible recovery, installing zip and app from HERE first.)

* 'Cyanogenmod' hotplug within Synapse is now 'Stock'. It will bring all CPUs online (as in stock. Reinstall ROM and then this kernel build if you are on previous build of this kernel.)

[Nexus 6  Original Android Development] michmeister:
Do we have to download multirom or can we just update kernel?
[Nexus 6  Original Android Development] SaZh047:
Hey I have a question which is not really related to this kernel. Its more a general battery related question :).

Why do I have 35 minutes of sot when I go from 100% to 95% and then 25 minutes of sot when I go from 95% to 90% even though I do the exact same thing... Kinda weird to me [emoji14]

You can remove this post if its too irrelevant :D
[Nexus 6  Original Android Development] wrongway213:
Just update kernel if you're not gonna use MultiROM
[Nexus 6  Original Android Development] Skripka:
Nice update! MultiROM works fine here. One bug...I select "Stock" in Hotplug driver, and the SoC is still parking CPUs 2 and 3 when idle rather than onlining them always (was just playing with configurations, I know I could manually set the min CPUs online)

[MENTION=3795148]neobuddy89[/MENTION] is something different about busybox on 03-30 nightly? Busybox appears to be installed but I've never got this message before on your kernel.
[Nexus 6  Original Android Development] Skripka:
Yea I tried rolling the dice and not reflashing ROM (it hadn't been necessary before). Unsurprisingly, you're right. :o
[Nexus 6  Original Android Development] neobuddy89:
Last busybox update was 03/22 build. Also Hydra installs busybox at /sbin/*

V4A might require proper busybox at /system/xbin/ - something dependent on ROM.

Try Stericson bb?
[Nexus 6  Original Android Development] wrongway213:
Ah, I thought it conflicted installing external Busybox while using your kernel so I had not been doing so. Glad to know I am able to use Stericson's on here.
