Linux 6.4-rc4 - audio doesn't work

All,

I updated my laptop to Linux 6.4-rc4 and audio stopped working. I haven't done any debugging yet since this is my primary system.

Here are the audio hardware details:

lspci | grep Audio 05:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Renoir Radeon High Definition Audio Controller 05:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD] ACP/ACP3X/ACP6x Audio Coprocessor (rev 01) 05:00.6 Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h/19h HD Audio Controller

I see just the Dummy Output device in sound settings. I will start poking around later on today.

thanks, -- Shuah
