As a result, only HDMI audio devices are available (aplay -l shows NVIDIA/AMD HDMI outputs and USB devices, but no “Analog” outputs). This appears to be a missing quirk for this board revision. System information: Distro: Xubuntu 25.04 (development branch) Kernel version: $ uname -r 6.14.0-32-generic linux-firmware package: 20250317.git1d4c88ee-0ubuntu1.6 Audio controller (lspci): 10:00.6 Audio device [0403]: Advanced Micro Devices, Inc. [AMD] Family 17h/19h/1ah HD Audio Controller [1022:15e3] DeviceName: Realtek ALC1220 Subsystem: Micro-Star International Co., Ltd. [MSI] Device [1462:ed75] Kernel driver in use: snd_hda_intel ALSA modules: $ cat /proc/asound/modules 0 snd_hda_intel 1 snd_hda_intel 2 snd_hda_intel 3 snd_usb_audio 4 snd_usb_audio Relevant dmesg logs: snd_hda_intel 0000:10:00.6: enabling device (0000 -> 0002) snd_hda_intel 0000:10:00.6: no codecs found! Expected result: ALC1220 analog audio devices should appear in aplay -l and be available in PulseAudio/PipeWire. Actual result: No analog audio devices, only HDMI/USB audio cards are available. Steps to reproduce: Boot Ubuntu/Xubuntu 25.04 with MSI MAG B650 Tomahawk. Run aplay -l. Observe that ALC1220 analog devices are missing. Check dmesg | grep hda → “no codecs found!”. Additional notes: BIOS setting HD Audio Controller is enabled. No “Front Panel Type” option available in BIOS. Problem persists with kernel boot parameters: snd-intel-dspcfg.dsp_driver=1 snd_hda_intel.model=alc1220 Latest linux-firmware installed. Same behavior confirmed on Ubuntu mainline kernel 6.14. ✅ Call to action Please add a quirk for subsystem 1462:ed75 (MSI MAG B650 Tomahawk, ALC1220).
