Hello, fellow XDA members!
Some of you may have heard of me before, and for the ones that haven't, let this be a warm introduction.
After hearing of the new Chromecast app with Beta support for mirroring, I decided to see if it's possible to enable for all devices. Apparently it is! :D
I assumed that some devices just wouldn't stream well, so I decided to mark this as [EXPERIMENTAL]. Please note that I did not make the feature, just the method to enable it.
Please alsenote that you need the latest version of the Chromecast companion app and root access on your device (not your chromecast) for this to work properly. The mirroring functionality requires KitKat 4.4.2 or higher.

Please note that under certain circumstances, some Samsung tabs may bootloop due to this modification. To be safe, do not enable the second option unless you ABSOLUTELY need to.

If this worked for you and you want to send some money my way (Keep in mind that I didn't make the mirroring, only the hack to enable it), feel free to visit my PayPal donation link in my signature. :)


For those STILL having issues,
Check /system/lib/hw directory for the file "audio.r_submix.default.so".
If it doesn't exist, ask your device maintainer to add audio.r_submix.default to
the product_packages in the device.mk file. (You may not know what it means, but they will.)
EXAMPLE (Thanks, @runandhide05!):
http://review.teameos.org/#/c/389/

(Thanks, @hwong96.)

What exactly is required for this to work?
(This is the technical aspect of getting mirroring to work)

(Straight from Google)
* The WiFi radio must support WiFi P2P.
* The WiFi radio must support concurrent connections to the WiFi display and to an access point.
* The Audio Flinger audio_policy.conf file must specify a rule for the "r_submix" remote submix module. This module is used to record and stream system audio output to the WiFi display encoder in the media server.
* The remote submix module "audio.r_submix.default" must be installed on the device.
* The device must be provisioned with HDCP keys (for protected content).

https://www.androidfilehost.com/?fid=95784891001616583

Here are all of the previous releases: http://www.androidfilehost.com/?a=show&w=files&flid=16506

Changelog:

v7
- Lollipop support
- Bug fixes
- This modification now works on ALL devices KitKat and up. (Including x86, hopefully)
- Mirroring might work better on Lollipop. We only learn by testing, right?

v6
- Bug fix with sqlite3

v5
- Added PurpleHoloLight Theme!
- Added an audio remote submix file check.

v4
- Fixed critical bugs

v3
- Added fix that may work for some
- Added " QuickSettings Mirror Tile" option

v2
- Added preinstalled sqlite3 binaries

v1

Please note that I tried to provide a safe, universal fix, but unfortunately, this may STILL not work on some devices. If it does not work for you, let me know and I will try to fix it (again). :)
Please note that this has the potential to mess up audio on your device, but it creates a backup that you can restore from by "Disabling" the fix.

Sadly, you may add the Asus ft700t running 4.4.4 (CROMBi-kk/CM11) to the list of not working devices. It appears in the settings menu and launches the Chromecast but immediately closes without casting.

v7 of #MirrorEnabler is now out!
What's new in this version?
- Lollipop support!
- x86 support (haven't tested, I need someone to test for me)
- Many bug fixes

If you are running any previous version (including the v7 betas), I highly recommend updating to this release. If you have any problems, grab a logcat immediately and send me a PM. :)

And, the updated source code can be found on my Github, too. :D

First off, thank you for your effort.

Just tried this on my S3 (International) and Asus Transformer Tf300t, no joy.

It seems to install on the S3, but I don't see the option for cast screen, as for my Asus, it won't even install. :(

Maybe I'm doing something wrong, or I've missed something, I just got the Chrome Cast yesterday.

Cast from Quick Settings work on Galaxy S4 with Lollipop 5.0 CyanogenMod12.

The screen casts normally. But if I try to play music from any music app, the casting freezes, and the music is played on the phone.
Any fix? Probably a Media cast block in Lollipop??

Tried MirrorEnabler on my rooted SM-T900 (Tab Pro 12.2) but can not get to work. I do see there is a workaround for samsung devices but I just cant find system/etc/wfdconfig.xml. Did a search in ES File Explorer but still cant find it....

I still get only a quick connect and then casting ends, same with V 6 or 7 and despite installing the binaries suggested here. Running Temasek V1.3, N9005. Could my GAPPS (gapps-lp-20141109-signed.zip) be a factor? If so, how can I change, as I tried to flash pa_gapps-micro-5.0-ALPHA1-20141117a-signed (1).zip last time I installed, but got an error msg that it was incompatible??

I'm not sure what device that is. You should point the device maintainer (the person that made the ROM you're on) to the OP and ask them to add the remote submix audio module to the device tree as well as add a few other changes (those are in the OP, too).

    DISABLE THE SECOND OPTION IN MIRRORENABLER FIRST!
    hwong96 said:
    I'll explain it in a way so you can edit the audio_policy.conf file yourself. The audio_policy.conf file is unique to each model in a manufacturer's lineup and between manufacturers. That is due to the different audio hardware installed on the device. It is more prevalent in older devices, not so much in newer devices. The force close fix option #2 in MirrorEnabler is more of a generic fix.

    If you are up to the challenge, here are the steps to edit your own audio_policy.conf file-
    1. If you applied option #2 in MirrorEnabler, de-select and reboot device to reset the manufacturer audio_policy.conf file.
    2. Make a backup of the manufacturer's audio_policy.conf file in the event you need to restore it.
    3. Open your audio_policy.conf file.
    4. Open the this pdf file and copy the red highlighted words from the global configuration section. Paste into your global configuration section as shown. Make sure to include the pipe.
    5. Copy the r_submix section highlighted in red and paste into your file as shown. You should have 4 }s at the end. Sampling rate should be 48000.
    6. Save your file.
    7. Reboot.

    Use MirrorEnabler without selecting option #2. You no longer need it if you edit your own audio_policy.conf file.

    You now have your device manufacturer's audio_policy.conf file with the audio.r_submix module added. You still need to make sure the audio.r_submix.default.so is baked into the rom. Look in /system/lib/hw. On newer devices look in /system/lib for libaudio.r_submix.default.so.

    Not much more I can say.

    For the curious: a fix is incoming soon(v3), it will not work on the HTC One M8 on stock (it will work on CM). It fixes the Google Play Services Force Close issues once and for all!
    Oh, it might also have a little surprise. :) Stay tuned.

    Unfortunately, it seems, even after all of the logcats and testers (thank you, by the way), fixing the Play Services force-close is beyond my current knowledge. To those with the Play Services force-close, I apologize for the inconvenience and hope you all get it resolved. :)
