Ubuntu 22.04.1 No sound cards found (was working, but no longer)

So until a day or two ago sound was working fine on my Ubuntu 22.04.4 LTS system, either over the headphone jack or USB audio. Now I have no sound and only the dummy device is present in the settings as a sounds output device.

I am looking for assistance in getting my sound outputs back.

Some diagnostic information:

I have booted into Windows and sounds seems to be working fine there so the hardware looks to be OK.

Some addition information from dmesg (not sure if it is relevant):

[    5.571290] sof-audio-pci-intel-tgl 0000:00:1f.3: Direct firmware load for intel/sof-tplg/sof-tgl-es8336-dmic2ch-ssp0.tplg failed with error -2[    5.571294] sof-audio-pci-intel-tgl 0000:00:1f.3: error: tplg request firmware intel/sof-tplg/sof-tgl-es8336-dmic2ch-ssp0.tplg failed err: -2[    5.571321] sof-audio-pci-intel-tgl 0000:00:1f.3: you may need to download the firmware from https://github.com/thesofproject/sof-bin/[    5.571339] sof-audio-pci-intel-tgl 0000:00:1f.3: error: failed to load DSP topology -2[    5.571354] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_component_probe on 0000:00:1f.3: -2[    5.571382] sof-essx8336 sof-essx8336: ASoC: failed to instantiate card -2[    5.571451] sof-essx8336 sof-essx8336: snd_soc_register_card failed: -2[    5.571464] sof-essx8336: probe of sof-essx8336 failed with error -2

Any suggestions would be welcome. If there's any additional information that would be helpful let me know and I will add it to the question.
