AMD HDMI Audio crackling

PC is connected to a TV via HDMI. There's crackling for a couple of seconds whenever audio starts playing. It doesn't matter if is it's a game, startup movie or Firefox playing a YT video. I've tried several "fixes" for crackling/popping audio with Pipewire and nothing seems to fix the issue. Bazzite running on Ryzen 5800X3D and Radeon RX 6800XT.

I have the same issue, 7900xtx and 5800X3D. I've tried the launch option parameter, editing pipewire config and grub parameters. I have also tried using the motherboard hdmi port to my audio reciever instead of the GPU, but i still get constant audio cut-out, crackling and stutters.

I have almost the exact same setup except for a 7800X3D processor and I have the same crackling audio for a few seconds after everything has been silent for a while. It does go away completely as long as there is some audio coming from the speakers but returns after a period of no audio.

Seem to have fixed it. I changed a few things so i'm not sure exactly what did it. Make sure /etc/system76-scheduler/config.kdl is unmodified. Install pavucontrol and disable USB audio. Copy /usr/share/pipewire/pipewire.conf to /etc/pipewire/pipewire.conf Play around with the these parameters (this is what i currently have set and working): default.clock.rate = 192000 default.clock.quantum = 512 default.clock.min-quantum = 32 default.clock.max-quantum = 4096 Make sure to restart the system76 scheduler after modifying pipewire.conf systemctl restart com.system76.Scheduler.service Run: ps -e -o pid,uid,pri,nice,rtprio,vsz,rss,tty,stat,start,time,comm | grep -E 'PID|pipewire' And make sure RTPRIO is set to 49 like so: PID UID PRI NI RTPRIO VSZ RSS TT STAT STARTED TIME COMMAND 5728 1000 89 - 49 431708 42652 ?
