@Hui Wang I installed your package and rebooted. It seems to fix the issue, audio is working as expected again.
One thing I noticed is that when I mute the speakers or microphone via their media keys (F1 and F4) the LEDs on the keys don't light up. It may not be related to this issue though because when I activate the FnLock the LED on the Esc key also doesn't light up. -- 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/1901157 Title: [Raven/Raven2/FireFlight/Renoir AMD Ryzen] No Sound at all Status in alsa-driver package in Ubuntu: Confirmed Bug description: After Upgrading to Ubuntu 20.10 (From 20.04) I noticed, that my Audio Output didn't work anymore. Switching between different Kernel Versions (Mainline 5.8.16 and Ubuntu Stock 5.8.0-25, 5.4.0-52) doesn't change that. Even on a fresh 20.10 Livesystem i get the exact same problem (On 20.04 Livesystem it works) An Output of "$ lspci -nnk | grep -A2 Audio" shows that the Output device uses the wrong Kernel Module (Audio Input is working since it uses the correct kernel module and driver) 07:00.1 Audio device [0403]: Advanced Micro Devices, Inc.
