Package: linux-config-5.9
Version: 5.9.1-1
Severity: normal

Dear Maintainer,

My Lenovo T14 AMD laptop does not show a selectable microphone device. 
lspci -v shows a device without a driver attached and I assume that to be the related hardware:

07:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD] Raven/Raven2/FireFlight/Renoir Audio Processor (rev 01)
	Subsystem: Lenovo Raven/Raven2/FireFlight/Renoir Audio Processor
	Flags: fast devsel, IRQ 255, IOMMU group 8
	Memory at fd380000 (32-bit, non-prefetchable) [disabled] [size=256K]
	Capabilities: <access denied>

arch linux shows that the following requirements are needed though I am not well educated in Linux to know if this does apply:

"On the AMD version, the internal microphone requires a kernel version of at least 5.8-rc7 with CONFIG_SND_SOC_AMD_RENOIR=m and CONFIG_SND_SOC_AMD_RENOIR_MACH=m.
 4-pin jack plugs work with a linux kernel of 5.7."

I am currently on Bullseye 5.9 kernel.

Thank you
