Thank you my dear friend @ckpv5 . I have issues with My Sony Android TV (Sony KD-49X8000G) due to the apps is not supported (but appear in the PLay Store, weird).
The com.tm.unifitv.mod-1.1.14.apk done the job perfectly, there is no issues so far. Everything is functioning well, change audio, subtitle and even picture quality.

Once again, thank you!
