And today I also hit this on the sc8280xp CRD reference design, so as
expected, there is nothing SoC specific about the audio service
regression either:

[   11.235564] PDR: avs/audio get domain list txn wait failed: -110
[   11.241976] PDR: service lookup for avs/audio failed: -110

even if it may be masked by random changes in timing.

These means it affects also machines like the X13s which already have
audio enabled.

Hopefully Bjorn or Chris have some plan on how to address the audio
regression.
