Describe the bug:
No audio output on an HP EliteBook (Intel Tiger Lake, PCI ID 8086:a0c8, "Tiger Lake-LP Smart Sound Technology Audio Controller"). The SOF driver fails to boot the onboard DSP entirely — no PCM device is ever created, so nothing shows up in pactl/wpctl/pavucontrol beyond a Dummy Output. System-wide, not app-specific.
Environment:
HP EliteBook, Intel Tiger Lake, PCI ID 8086:a0c8
Kernel driver in use: sof-audio-pci-intel-tgl
Kernel: 7.1.9-arch1-2
Distro: Omarchy (Arch-based)
Audio stack: PipeWire + WirePlumber
sof-firmware: 2025.12.2-1 (installed, confirmed current — not a missing-package issue)
dmesg output:

sof-audio-pci-intel-tgl 0000:00:1f.3: error: dsp core reset failed: core_mask 1
What I tried:
Confirmed sof-firmware was installed at a current version, and PipeWire/WirePlumber were running clean with no errors of their own — ruled those out before tracing it to the kernel log above.
Workaround that fixed it:
sudo mkdir -p /etc/modprobe.d
echo "options snd-intel-dspcfg dsp_driver=1" | sudo tee /etc/modprobe.d/no-sof.conf
sudo mkinitcpio -P
On Omarchy this also needs limine-mkinitcpio afterward to update the Limine boot entries — distro-specific, not relevant upstream.
Speaker output works after reboot. Not yet confirmed whether this disables the digital mic array, which other EliteBook reports say depends on SOF.
Additional context:
Same error signature (dsp init failed after 3 attempts with err: -110, cl_dsp_init: timeout with rom_status_reg) shows up in reports on other hardware sharing PCI ID 8086:a0c8 looks like a DSP boot timing issue on this controller generation broadly, not this specific laptop.
