Bug Description
On 22 March, 2020 I ran the latest update as requested by the computer. After rebooting, as requested, I no longer have sound & the only sound output is "Dummy Output".
No sound card is detected but i have a Multimedia Audio Controller Intel Corp Device 9dc8(rev30) installed.
After running Ubuntu-bug in terminal I get:
