Hi all,
I just got myself a Sapphire Pulse 7900xt to replace a RTX 2060. I DDU'd the nvidia stuff. Installed the card in, installed AMD driver. All is well, no crashes, no issues except for this weird one:
- When playing back bitstream audio from VLC / MPC-BE or Netflix app (from the MS store), the audio drops randomly every so often. Very random.
My setup is detailed below but I run an HDMI (certified 48 Gbps capable) cable from the card to an AVR (Yamaha) and another from the AVR to a TV (1080p).
Facts:
Audio was fine with the exact same setup with the RTX 2060
All HDMI cables are certified to carry the full 48 Gbps of HDMI 2.1a signal
The audio is perfect when using PCM (in games for example)
The issue occurs no matter what format is being bitstreamed, can be Dolby digital, can be DTS... no matter)
System specs:
Gigabyte B550i AX rev 1.0 running BIOS F18, the onboard audio is disabled in the BIOS
Ryzen 5700x with negative curve -30 on all cores, rest is stock
1To NVMe PCIe 4.0 storage
32 Corsair DDR4 1800 Mhz
Sapphire Pulse 7900XT
AVR: Yamaha RX-V6a firmware 1.63
TV/Display: Sony EX500 (1080p 60Hz)
Troubleshooting so far:
- DDU the AMD driver once more in safe mode and reinstall with the minimal install option
- used the AMD cleanup utility and reinstall drivers
- DDU again in safe mode to install latest version (23.8.1 both full and minimal)
- tried connecting to the TV and use ARC but that is not satisfactory as TV doesn't support eARC which limits greatly the use of the setup - I have plans to upgrade the unit soon so maybe that'll work around the problem (which is why i got this GPU in the first place)
- used a Display port to HDMI cable (as suggested elsewhere on this forum and reddit) which did NOT work at all
HDMI audio seems to be an ongoing issue with AMD cards and AVRs ever since the RX 5000 series (as per different entries I could find in this forum and / or reddit), this should be addressed. We're not a vast majority to be using GPUs with these setups but it's been years now, do something.
