Troubleshooting an incomplete switch from pulseaudio to pipewire

Sometime around November or December of last year a program I had migrated it's audio dependency from pulse* to pipewire. I followed the arch manual to remove the collection of pulse packages and install / configure my pipewire service. At least to the best of my understanding, and I think it was partially successful. Ever since then I've been able to connect to the following audio devices 1) a USB headset; 2) my bluetooth headphones; 3) TV speakers accessible through an HDMI connection.  The other-side of the coin is that I've had no problems with USB based microphones.

The problem, is my speakers, connected to an audio jack directly connected to my motherboard aren't detected anymore. I've tested that the speakers and my onboard jack work by booting into an alternate OS. I use the BIOS to select my bootable drive when I'm not booting by default into my Arch system.

My arch system was installed in 2012, and I've rarely had significant problems, but I have experimented numerous times over the years with some program setups, that I may not have fully understood, to provide capabilities around midi, recording servers, self-hosted video conferencing etc., while I never got many of those working, I wouldn't be surprised if I have ended residual packages or conf files that could be interfering.

I revisit this problem usually about once a month and I've tried just about everything I can find from a google search, so I'm not sure where to start anymore. I've installed many parallel programs like firmware_utils and I've tried ensuring the systemd services were properly running. When I reopened the PipeWire ArchWiki  today the following section caught my eye:

3.1.9 Switching between device profiles
Some hardware audio devices, like snd_hda_intel, function differently depending on which profile the device is running in. In the case of snd_hda_intel, there are separate profiles for HDMI and analog output.

snd_hda_intel is something I think is relevant to my hardware and there was a post I tried following by adding it to the blacklist, but this didn't change anything so I reverted. I haven't tried customizing "profiles" as I'm not sure I have enough information to make an attempt for a hardware specific profile, and I'll admit to being a little cautious as I don't want to loose my current plug-and-play USB + HDMI audio capabilities.

The result of pactl info which is currently outputting (crackly) audio to a USB headset:

pactl info

Default Source: alsa_input.usb-DSEA_A_S_EPOS_ADAPT_1x5_A003640212601111_00-00.mono-fallback

Anyone have a similar issue and/or have any troubleshooting advice?  I've tried to post this a few times, but it appears I'm taking to long trying to add supporting outputs and this forum post-page times out. My apologies if in my haste this time to beat the expiration I've neglected information I previously had that I should have continued to prioritize. I'll provide any requested diagnostic output as soon as possible!

Re: Troubleshooting an incomplete switch from pulseaudio to pipewire

Please use code rather than quote tags for outputs. Adjust your OP in this regard and post the outputs of

sudo fuser -v /dev/snd/*
aplay -lL
pacman -Qs 'wire|pulse'
systemctl --user status pipewire{,-pulse} wireplumber pulseaudio
