It turns out that after following the below guide, I found that another package called timidity is conflicting with PulseAudio and causing it to fail detecting my audio devices. So I uninstalled it and PulseAudio is now working fine.
sudo apt-get remove timidity https://wiki.archlinux.org/title/PulseAudio/Troubleshooting#The_only_device_shown_is_%22dummy_output%22_or_newly_connected_cards_are_not_detected I ran this command: HP-Pavilion-dv6-Notebook-PC:~$ sudo fuser -v /dev/snd/* USER PID ACCESS COMMAND /dev/snd/controlC0: timidity 852 F.... timidity /dev/snd/controlC1: rana 7346 F.... pulseaudio /dev/snd/pcmC0D0p: timidity 852 F...m timidity /dev/snd/seq: timidity 852 F.... timidity /dev/snd/timer: timidity 852 f.... timidity ** Changed in: pulseaudio (Ubuntu) Status: New => Invalid ** Converted to question: https://answers.launchpad.net/ubuntu/+source/pulseaudio/+question/699628 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1952154 Title: [HP Pavilion dv6 Notebook PC, IDT 92HD75B3X5, Speaker, Internal] Pulseaudio fails to detect card Status in pulseaudio package in Ubuntu: Invalid Bug description: [HP Pavilion dv6 Notebook PC, IDT 92HD75B3X5, Speaker, Internal] Pulseaudio fails to detect card ProblemType: Bug DistroRelease: Ubuntu 21.10 Package: pulseaudio 1:15.0+dfsg1-1ubuntu2 ProcVersionSignature: Ubuntu 5.13.0-21.21-generic 5.13.18 Uname: Linux 5.13.0-21-generic x86_64 ApportVersion: 2.20.11-0ubuntu71 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: rana 1031 F.... pulseaudio CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Thu Nov 25 03:08:15 2021 InstallationDate: Installed on 2021-11-16 (8 days ago) InstallationMedia: Ubuntu 21.10 "Impish Indri" - Release amd64 (20211012) SourcePackage: pulseaudio Symptom: audio Symptom_Card: HDA-Intel - HDA Intel MID Symptom_Jack: Speaker, Internal Title: [HP Pavilion dv6 Notebook PC, IDT 92HD75B3X5, Speaker, Internal] Pulseaudio fails to detect card UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 05/17/2010 dmi.bios.release: 15.28 dmi.bios.vendor: Hewlett-Packard dmi.bios.version: F.1C dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 3659 dmi.board.vendor: Hewlett-Packard dmi.board.version: 32.25 dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: N/A dmi.ec.firmware.release: 50.37 dmi.modalias: dmi:bvnHewlett-Packard:bvrF.1C:bd05/17/2010:br15.28:efr50.37:svnHewlett-Packard:pnHPPaviliondv6NotebookPC:pvr049D210000241210000020000:rvnHewlett-Packard:rn3659:rvr32.25:cvnHewlett-Packard:ct10:cvrN/A:skuWE049EA#ABV: dmi.product.family: 103C_5335KV dmi.product.name: HP Pavilion dv6 Notebook PC dmi.product.sku: WE049EA#ABV dmi.product.version: 049D210000241210000020000 dmi.sys.vendor: Hewlett-Packard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1952154/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
