No Speaker Audio on HP Dragonfly Pro One (Headphone & Bluetooth audio work fine)

Sorry if this is missing any critical information; I was not able to find the issues & assistance template. If I need to provide any more info please let me know.

I’ve used Cachy on desktop for over a year now and I’ve also used it on a few laptops with no major issues.

I just got a used HP Dragonfly Pro One and I have no output from the built-in speakers at all. I’ve tried everything I’ve been able to find and had no success.

I’m only allowed 2 links per post so I’ll drop the options in alsamixer in a comment. As best I can tell, all these HD-Audio outputs are the HDMI outputs for the USBC ports on the laptop. They are all recognized and if selected receive audio. Bluetooth and USBC-to-3.5mm adapters all work as well (the laptop has no dedicated 3.5mm port).

The other sound card option in alsamixer, “acp6x”, only shows “This sound device does not have any controls.” My hw-probe output is here. It shows the snd_hda_intel sound driver as “detected,” not “working,” but other drivers that show “detected” like the touchpad work fine so I’m not sure if that’s even relevant.

I found this info about configuring the acp6x driver, but frankly I do not understand what to do with that information. If that’s my solution, could someone please help me to impliment it?

Here is my output for

>dmidecode -t baseboard

>cat /proc/asound/modules

and

>wpctl status

❯ sudo dmidecode -t baseboard

I think this is everything I’ve been able to find so far. If anyone is able to help I would appreciate it so much!

edit: I know that the speakers work because when I got the laptop it had Windows 11 on it and the speakers worked great. Also in my troubleshooting I loaded a Linux Mint live environment to see if that made a difference, and no it did not. My only audio output in Mint was a “dummy output” and it did nothing.

I also found this post on the Manjaro forum from someone who had a similar issue involving the acp6x driver with a microphone on an Asus laptop. Apparently they solved it by patching the kernel. If that is a potential solution for my issue, I may need a little more guidance because i read though that post and it was a bit over my head.
