I installed Manjaro KDE on my laptop alongside Windows on a seperate SSD, and the sound output flat-out doesn’t work, neither from the speakers or the headphone jack. I check the audio devices, and I see the “GP107GL High Definition Audio Controller” listed under “Inactive Cards”, and a “Dummy Output” was created in its place. The built in microphone also doesn’t show up, but my external USB ones do.
I’ve tried doing plenty of troubleshooting here on the forums, such as upgrading and downgrading the kernel (currently on 5.15.2-2), disabling PipeWare because it allegedly interferes with PulseAudio, reinstalling sof, and nothing has worked.
My inxi Fazy’s audio section:
Edit (12/11/2021): I have upgraded the kernel to 5.15.6-2, but my audio issues persist.
Welcome to Manjaro forum
Audio device NVIDIA GP107GL is usually set to profile Off because most users do not use HDMI digital audio output to an external monitor
Device Intel Cannon Lake PCH should support the internal digital microphone array; analog built-in speakers and analog audio to the headphone/headset/microphone jacksof-audio-pci-intel-cnl is in use
Please post more information about audio devices and drivers in ALSA

There are no errors or anything unexpected for this device showing in ALSA so this is probably an issue with PulseAudio

You should consider updating system BIOSHP Pavilion Gaming 15-cx0000 Laptop PC Software and Driver Downloads | HP® Customer Support
Then Unplug the USB audio devices and clear user settings for PulseAudio
rm ~/.config/pulse/cookie ~/.config/pulse/*.tdb
and reboot system
If audio is still not working, please post the full response for system information

ALSA data is showing the same errors as before & fails to detect any playback or capture devices for the onboard audio
Arch Wiki page for this laptop suggests audio should work without problemsHP Pavilion 15-cx0xxx - ArchWiki
Linux hardware scans for this laptop model show some systems with older BIOS versions have similar problems with missing audio devices in ALSA
