Public bug reported: [Impact] HP systems with TI TAS2783 SoundWire speaker amplifiers (subsystem ID 8F6D) have no sound from the built-in speakers on Ubuntu 26.04 (resolute).
The tas2783 driver needs a tuning/calibration binary for each amplifier. These are the ti/audio/tas2783/8F6D-0-0x*.bin files. linux-firmware in resolute does not ship them, so the amplifier does not initialize. Affected: HP ZBook Ultra 16-inch workstation. [Fix] Cherry-pick the upstream linux-firmware commit that adds the TAS2783A firmware files and their WHENCE entries: 2f90f4fe5c67 ASoC: tas2783: Add Firmware files for tas2783A projects Upstream linux-firmware in 20260519. Mailing list: https://lore.kernel.org/lkml/[email protected]/ The commit adds 8F6D-0-0x9, 0xA, 0xC and 0xD .bin files. It also adds files for other TAS2783A projects and reworks the tas2783 section of WHENCE. [Test Plan] Install the updated linux-firmware on an affected HP system. The kernel must have the tas2783 driver patches. Then: $ ls /lib/firmware/ti/audio/tas2783/8F6D-0-0x.bin $ sudo reboot $ dmesg | grep -i tas2783 $ speaker-test -c 2 -t wav Without patch: the 8F6D-0-0x*.bin files are missing. dmesg shows a firmware load failure for tas2783. No sound from the built-in speakers. With patch: the files exist, dmesg shows no firmware load error, and sound plays from the built-in speakers. [Where problems could occur] This could break firmware loading for other tas2783 systems. The commit also changes WHENCE entries (some Link: lines are removed and rewritten).If a link is wrong, tas2783 would fail to find its file on those systems. Audio would be silent and dmesg would show a firmware load error. The package build checks WHENCE. A bad WHENCE entry could fail the linux-firmware build or leave files out of the package. The change adds binary files only, so no other firmware is touched. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux-firmware (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: linux-firmware (Ubuntu Resolute) Importance: Undecided Assignee: AceLan Kao (acelankao) Status: In Progress ** Affects: linux-firmware (Ubuntu Stonking) Importance: Undecided Status: Fix Released ** Tags: jira-stella-4236 oem-priority stella ** Also affects: linux-firmware (Ubuntu Stonking) Importance: Undecided Status: New ** Also affects: linux-firmware (Ubuntu Resolute) Importance: Undecided Status: New ** Changed in: linux-firmware (Ubuntu Resolute) Status: New => In Progress ** Changed in: linux-firmware (Ubuntu Resolute) Assignee: (unassigned) => AceLan Kao (acelankao) ** Changed in: linux-firmware (Ubuntu Stonking) Status: New => Fix Released ** Tags added: jira-stella-4236 oem-priority stella -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2169111 Title: No built-in speaker audio on HP systems with TI TAS2783 amplifiers To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2169111/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
