Pipewire - Inconsistent volume and channel dropping after suspend

I have recently replaced pulseaudio with pipewire and wireplumber due to an issue with my sound devices disappearing when changing speaker profiles and have run into the following issues (that I think were also present with pulse). Pipewire is using the default configuration settings.

I have a SoundBlaster Z that works perfectly until my system resumes from suspend. I do not have any software equalizer installed or configured, just one of the hardware eq profiles selected in alsamixer. Once my system resumes from a suspended state, when playing any audio, the volume level fluctuates almost like there is volume normalization going on. The volume indicated in pavucontrol does not visually show the volume is being raised or lowered, but something is certainly going on in the background. At the same time this occurs, but not always, the right and left channels drop out at different intervals. Restarting pipewire, pipewire-pulse, and wireplumber do not have any effect on this issue. Audio is only restored to normal upon reboot.

I am running kernel 6.1 but this issue occurs under 6.0 as well.

I have an arch install that I have done some testing on separately and I do not have these same issues. I copied the config from that install to my manjaro installation (prompting a switch from pipewire-media-session to wireplumber) and it seemed to work better, but the issue has re-appeared after today’s update.

Any advice is greatly appreciated.

After reading everything I could find about the Sound Blaster Z and tweaking config files to no avail I ultimately decided to retire the Z and replace it with a Sound Blaster X4 usb dac. I hate to retire the Z since its a great card in Windows, but the issues I was facing were a deal breaker.

Going with a Creative device once again was a gamble and I was fully expecting to have to return it but I have been incredibly happy with the sound and performance of the X4. In typical Creative fashion, all of the features are not available to linux users, but sacrifices must be made I guess.
