Update: I was able to get the speakers to make sound by installing linux-oem and by allowing updates from focal-proposed.
As expected, alsamixer now shows a lot of options. There are still a few issues: 1) The audio is stuttery, most playback is too fast (e.g. YouTube or MP3s), and other playback doesn't work at all (e.g. Zoom). 2) The microphone is not detected. Further, lspci still doesn't show the Realtek card. ** Summary changed: - Sound card not detected on Dell Latitude 9510 + Sound card not detected on Dell Latitude 9510 (Realtek ALC711) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1895422 Title: Sound card not detected on Dell Latitude 9510 (Realtek ALC711) Status in alsa-driver package in Ubuntu: New Bug description: I am running Ubuntu 20.04.01 LTS, kernel version 5.6.0-1027-oem (checked via uname -r). 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/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
