Public bug reported:
I’m using Ubuntu 26.10 (Stonking Stingray) on an HP OmniBook X
LaptopNGAI 14-ka0073cl with an Intel Core Ultra Series 3 processor. The
built-in speakers do not appear as an audio output. PipeWire shows only
“Dummy Output.”
The Intel audio controller is detected and uses sof-audio-pci-intel-ptl,
but ALSA lists only “Jack Out” and HDMI playback devices—no built-in
speakers. The kernel log reports that TAS2783 amplifier firmware files
are missing.
System details
Laptop: HP OmniBook X LaptopNGAI 14-ka0073cl
Ubuntu: 26.10 (Stonking Stingray)
Kernel: 7.3.0-9-generic
Audio controller: 8086:e428, HP subsystem `103c:8ea6
Driver: sof-audio-pci-intel-ptl
linux-firmware: 20260915.git1522c78a.1ubuntu
firmware-sof-signed: 2026.09-1
Relevant log messages
text
No SoundWire machine driver found for the ACPI-reported configuration
Use SoundWire default machine driver with function topologies
Topology: ABI 3:29:1 Kernel ABI 3:23:1
Direct firmware load for 8EA6-2-0x9.bin failed with error -2
Direct firmware load for 8EA6-2-9.bin failed with error -2
Direct firmware load for 8EA6-2-0xC.bin failed with error -2
Direct firmware load for 8EA6-2-C.bin failed with error -2
The files matching /lib/firmware/8EA6-2-* are not present. Both firmware
packages above are installed at the listed versions.
How to reproduce
Boot Ubuntu 26.10 on this laptop.
Open Settings → Sound, or run wpctl status.
Observe that no built-in speaker output is available; PipeWire reports
“Dummy Output.”
Expected result: The built-in speakers are detected and available as an
audio output.
Could you advise whether the required HP/TAS2783 firmware files and a
matching SOF topology/kernel configuration can be added or otherwise
supported?
