After a Tumbleweed update to "20220402" (with kernel 5.17.1-1-default) the card is no longer generating any sound, even when I attempt to manually send a sound file to it (e.g. by playing one of the KDE notification sounds).

Could you give more detailed description? From which system did you update? If you have been running TW, can you try rollback? If the rollback can't be used, at least, can you try to boot with the older kernel that had worked, and see whether the same problem is seen? In anyway, please give alsa-info.sh outputs from both old and new kernels. Run the script with --no-upload option and attach the outputs to Bugzilla.

Examination of the systemd log shows that a firmware file failed to load for the sound device.

I've attached an extract of the systemd log relating to the sound card; it shows the error message when loading the firmware and the card being effectively disabled as a direct consequence.

Judging from the log, you have two sound cards, at least, one is an onboard audio and another a CA0132-based audio. Maybe both are onboard, but I can't check it. The error about the firmware error is for CA0132, and this must be present in the older kernel, too, unless you mistakenly uninstall the corresponding firmware package (kernel-firmware-sound and alsa-firmware). The onboard audio shows, OTOH, another problem, the codec communication. It went into a fallback mode, which works somehow but imperfectly (e.g. the jack detection won't work in this mode). You need to check with the status with the older kernel to see whether it's a new problem or not, too. -- You are receiving this mail because: You are on the CC list for the bug.

In anyway, it's a BIOS bug :) Let's close now. Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
