Windows 10: Updated to Version 1803, HDMI audio on TV

Hey, sorry if this is in the wrong section.

Basically I use Windows 10 64-bit and I just got done with the update to Version 1803. I often hook my laptop up to my LG TV via HDMI but now the TV audio no longer works, though the PC speakers are fine.

My laptop is an HP Envy TouchSmart, I recently reinstalled the IDT Audio driver (sp63555.exe) and that has the speakers working fine but it won't detect the TV speakers. Tried looking online but couldn't find anything that worked.

Let me know if more details are needed or if this is in the wrong places.

Thanks in advance!

Microsoft Edge interferes with HDMI audio

I stream TV using a browser and connect to TV via HDMI output. Some resent update eliminated the HDMI audio from the output signal. There was no change in the audio driver and the HDMI audio controls seem unaffected but there is no audio output.

To check on whether it is a Microsoft Edge problem I downloaded and installed the Chrome broswer. The HDMI audio works well streaming under Chrome but not Microsoft Edge.

Is there a fix or workaround for HDMI audio under the latest version of Microsoft Edge?

This is very problematic for videostreaming. Thanks

 

Failed to Play Test Tone, after use of Netflix with HDMI to TV.

Windows 10 version 1709 (OS Build 16299.64)

HP ENVY x360 m6 Convertable PC

Yes this is the first time the Samsung TV was connected to this PC. Infact the HDMI audio to the TV did not work when first connected, but began functioning after rebooting with the HDMI cable connected to PC and TV.

After disconnecting the PC from the TV and HDMI and rebooting several times I was browsing YouTube and when trying to play a video there was no PC audio to the speakers or out the audio jack or USB port. Also no audio from Media Player when playing mp3s.

I was using Troubleshoot when I got the "Failed to Play Test Tone" message. No other errors reported. While trouble shooting found that the Intel Display Audio driver was out dated, and loaded the current. Some time later I heard a the Wins10 startup audio
but still not getting any more.

A similar situation happened to me earlier with Windows 10 on a different PC. The TV would need to be connected to the PC HDMI then reboot to get TV audio. After viewing the Netflix Movie, disconnect the HDMI and reboot the PC to get the audio back on the
PC. But this time on the current PC the audio did not return after multiple reboots and maybe a driver update.

I hope this is helpful.
