I own a N4 with stock 4.4.4, rooted, with Xposed framework and CF.Lumen app. Everytime I try to mirror/screencast my phone to my chromecast (plugged directly to my TV), Google Play Services crashes with the "stopped unexpectedly" message, and the TV screen goes black.
I've tried lots of stuff, like:
using the mirror enabler app FC fix;
using the mirror enable app remaining options;
uninstalling and reinstalling chromecast app;
disabling HDMI-CEC on the TV (Anynet+, as it's a Samsung).
Even with mirror enabler quicksettings option turned on, the tile never appears, regardless of GravityBox being active or not.
Casting from Allcast, Play Movies, Netflix, Google+, Youtube, Remotecast or any other app works perfectly. No issue at all.
I never installed Viper Audio (found a thread with it being the reason for screencast not to work) and audio.r_submix file is present (it's the stock ROM).
I feel like I may be missing something really simple, but I'm really lost.
Chromecast app version 1.7.4
Google Play Services 5.0.89 (1307510-036)
Chromecast firmware 17977, powered by an USB power adapter, plugged directly into one of the TV's HDMI ports.
WiFi network is 802.11g/n
