    Hi! Before May2020 update I used my external TV LG 19LE3308 for video/audio without any problem va HDMI.
    After the Update, I don't see the second screen as TV LG but now is "Intel AudioR Display Drivers - HDMI 1" and the audio doesn't work 99% of the time. I can't say 100% because at the startup, the audio works sometimes for some minutes, then it stops with a fuzzy sound from the LG speaker.
    I see volume indicator changing on playback during audio play without sounds from the speaker.

    The LG works perfectly with Linux and I tried without HDMI too antenna only not a TV issue.
    I also tried a Samsung TV but I have the same issue. I tried changing the HDMI cord without success.

    I opened a thread on Intel's forum. After checking my log, they made me install HP reccomended drivers from HP support webpage 20.19.15.5058 after uninstalling completely old drivers until I got 'Microsoft Basic Display Adapter' on Device manager.
    Same bugged behavior.
    I also upgraded LG TV firmware to 3.03.43 but the bug persists.

    I tried old Intel HD graphic drivers 15.40.42.5063 without success.

    Unfortunately I need to work with this laptop and at the moment restoring everything is not an feaseable option.


    Similar issues to mine found on reddit:

    How can I fix it or debug it?

    :)

    Audio lost to HDMI on LG smart tv.

    After the upgrade to 10 I no longer have HDMI audio on my LG Smart TV. I have tried several ways to restore it. I do have sound to the speakers plugged in to my sound card but prefer using the audio on the TV. Any suggestions?

    Okay, just tried this, Display Audio or anything mentioning the TV isn't on the list:

    HDMI audio output to Sony TV

    Hi,

    One possible reason why your HDMI audio output was not working due to outdated drivers. To isolate your issue, kindly answer the following questions:

    • Have you made any recent changes prior to this issue?
    • Did you get any error messages when you tried to connect your computer to your TV?
    • Have you tried updating your HDMI audio driver?
    • What troubleshooting steps have you done so far?

    We're looking forward to your response.
