I believe my sound card is not being detected by Ubuntu. I checked the serial number and via BIOS (which I've upgraded to the latest version) according to the specs (https://topics-cdn.dell.com/pdf/latitude-15-9510-2-in-1-laptop_owners-manual5_en-us.pdf) the sound controller/speaker should be Realtek ALC711-CG / Realtek ALC1309D. However, when I run lspci only the following device appears: 00:1f.3 Multimedia audio controller [0401]: Intel Corporation Device [8086:02c8] In alsamixer, only the HDMI port appears. alsa-info output: http://alsa- project.org/db/?f=f2b70f6eb1a237378bf563cacb6f192ce0a677c3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1895422/+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
