There is an issue with the LG OS with my smart tv UM7290. When i mute the Channels having 5.1 audio from dth remote and then unmute it, the sound is getting mute permanently. Only when i change the channel and come back to the same channel then i can hear the audio. I have dishTV as dth. My sony 4k smart tv is not having the same issue and working fine. Hence i am assuming the issue is only with LG one. steps: Mute a 5.1 audio channel for more then 5 seconds from dth remote-> then unmute. Unable to hear the sound
