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!
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!):
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).
Here are all of the previous releases: http://www.androidfilehost.com/?a=sh...les&flid=16506
- 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?
- Bug fix with sqlite3
- Added PurpleHoloLight Theme!
- Added an audio remote submix file check.
- Fixed critical bugs
- Added fix that may work for some
- Added " QuickSettings Mirror Tile" option
- Added preinstalled sqlite3 binaries
- Fixed critical bugs
- Initial release
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.

For those with audio issues after applying the Force-Close Fix:
DISABLE THE SECOND OPTION IN MIRRORENABLER FIRST!
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.
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.
