Re: RX5700 and HDMI sound problem

Do note that on my system after a boot I had to set it again on the Dolby Atmos for Home Theater. If I don't it is stuck on 7.1. So if it was after a reboot that it stopped working check that! I don't have the solution yet for keeping it on Dolby Atmos after a boot .

No problems yesterday while gaming, even multiple screens on and video playing in one of them. Before that I couldn't do that without weird audio drops or screen issues.

Edit:

Nope, unless my config is wrong somewhere it didn't work. Had after 5 hours artifacts and no audio, switching on receiver on/off solves it for a few hours though. It might be better than before but it is hard to tell.

Conclusion, the AMD HDMI driver sucks.

AMD Starts Rolling Out AGESA 1.0.0.5 BIOS Firmware 

  • Updated AMD AGESA ComboAm4PI 1.0.0.5
  • Fix HDMI audio lost issue when use AMD RX570 vga card.

I suppose "AMD RX570" its a typo and they actually meant RX5700.

Re: RX5700 and HDMI sound problem

Out of curiosity is anyone having these problems with an Intel MB? I'll test the new BIOS as soon as it's available for the B450 Tomahawk (non max)

Re: RX5700 and HDMI sound problem

The problem does not seem to be motherboard related, the problem comes from the graphics card.

Re: RX5700 and HDMI sound problem

I have check your workaround. unfortunately when I try to do bitstream with 5.1 format, the pc send PCM 2 channels to the AVR. In the sound information, it's seems the driver indicate the AVR can not support 5.1 format. I have try using mpcbe + lavfilters.

Bistreaming conf was working well before

Re: RX5700 and HDMI sound problem

I solved the audio cut out stuttering problem by using an older HDMI driver.
That's version 10.0.1.07.

Included in Radeon ™ Software Adrenalin Edition 18.10.1 

It is located in the package \ drivers \ audio \ hdmi \ WT64A folder.

https://www.amd.com/en/support/kb/release-notes/rn-rad-win-18-10-1

Please overwrite the driver via manual update and restart

i dont know why maybe audio cut out again 

try driver overwrite again restart

Re: RX5700 and HDMI sound problem

You should report the issue and how you fixed it with the older file to AMD. It may aid them in isolating why the current drivers are an issue. 

Send your results to AMD: https://www.amd.com/en/support/contact-email-form

Re: RX5700 and HDMI sound problem

Unfortunately this didn’t work for me. I’ve had these issues since day one when I got the card in October. Some games it’s fine but mostly it’s not. I originally had Windows in Dolby Atmos for Home Theater and that would make the audio go out indefinitely until you hit mute and then un-mute. Then it would just go out again after a few seconds. It was constant. But if I put Windows in 5.1, the audio cuts in and out constantly. I hate it. I tried downloading those old drivers and only installed the HDMI audio drivers but that didn’t work for me.
