I have been trying to set up a Minisforum HX90[1] with Debian stable with backports. Most of the stuff works out of the box except sound, bluetooth, and Wi-Fi. I'll focus on the sound card issue here and use a new thread for the latter 2 items (which are related to the same MediaTek module.) I've enabled backports repo and installed the latest backport kernel. It looks like the system can detect the device according to inxi output: but note this line: "Device-2: AMD Raven/Raven2/FireFlight/Renoir Audio Processor driver: N/A" which seems to suggest that the driver is not available. I tried to list devices using "aplay -l" but got no sound card available: Volume: front-left: 65536 / 100% / 0.00 dB, front-right: 65536 / 100% / 0.00 dB I've googled around and tried to install some firmware including "firmware-sof-signed" but it didn't help. The "lspci output" looks like: 04:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD] Raven/Raven2/FireFlight/Renoir Audio Processor (rev 01) Subsystem: Advanced Micro Devices, Inc. [AMD] Raven/Raven2/FireFlight/Renoir Audio Processor Memory at fca80000 (32-bit, non-prefetchable) [size=256K] Capabilities: [48] Vendor Specific Information: Len=08 <?> Capabilities: [64] Express Endpoint, MSI 00 Capabilities: [100] Vendor Specific Information: ID=0001 Rev=1 Len=010 <?> 04:00.6 Audio device: Advanced Micro Devices, Inc.

Family 17h (Models 10h-1fh) HD Audio Controller Capabilities: [100] Vendor Specific Information: ID=0001 Rev=1 Len=010 <?> The "lsmod" output seems to show that everything is loaded, but it seems the acp3x related modules are not in use: snd_hda_core 110592 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_pcm 147456 5 snd_hda_codec_hdmi,snd_hda_intel,snd_usb_audio,snd_hda_codec,snd_hda_core snd 114688 16 snd_seq_device,snd_hda_codec_hdmi,snd_hwdep,snd_hda_intel,snd_usb_audio,snd_usbmidi_lib,snd_hda_codec,snd_timer,snd_pcm,snd_rawmidi usbcore 327680 6 xhci_hcd,snd_usb_audio,usbhid,snd_usbmidi_lib,btusb,xhci_pci I'm not sure what to do about this, and there isn't much result from Googling that are related to Debian. Any suggestions are appreciated! And if there's any more info needed I'd like to provide if that helps.
