Hey all!
Due to the sound problem via HDMI to LG TV
One thing I've seen, (but don't know if it has to do with the audio problem with LG via HDMI) is that in the "/etc/audio_policy.conf" file, a number of lines are Remarked (blocked, REM or what it's called) with # (See below).
In another forum I did found a solution to get sound via HDMI to LG TV, but it is not possible to change the stockroom for a regular user.
When I compare to the same file in Android 6 these lines are not blocked with #
I don't know if this is a solution to the audio problem via HDMI on 7.1.2.
This is the solution I found:
Solution below to get sound via HDMI in 7.1.2
global_configuration {
attached_output_devices AUDIO_DEVICE_OUT_EARPIECE|AUDIO_DEVICE_OUT_SPEAKER|AUDIO_DEVICE_OUT_WIRED_HEADPHONE|AUDIO_DEVICE_OUT_AUX_DIGITAL
default_output_device AUDIO_DEVICE_OUT_AUX_DIGITAL
attached_input_devices AUDIO_DEVICE_IN_BUILTIN_MIC|AUDIO_DEVICE_IN_BACK_MIC|AUDIO_DEVICE_IN_VOICE_CALL|AUDIO_DEVICE_IN_REMOTE_SUBMIX
}
And this is the REMMED lines and different audio output in 7.1.2 (They are not REMMED in 6.0)
#global_configuration {
# attached_output_devices AUDIO_DEVICE_OUT_SPEAKER
# default_output_device AUDIO_DEVICE_OUT_SPEAKER
# attached_input_devices AUDIO_DEVICE_IN_BUILTIN_MIC|AUDIO_DEVICE_IN_REMOTE_SUBMIX|AUDIO_DEVICE_IN_DIA_REMOTE
#}
Please, don't be angry to me, I do not know if this solution would help, only you experts know!
