Such a file doesn't appear to exist in the sof repo that I can see. I think the best next step here would be to get Intel involved, probably the best would be to open a ticket on the sof GitHub: https://github.com/thesofproject/sof/issues If you could CC myself on that as well. If possible it would still be worth trying 7.3 as well. In theory this laptop was confirmed as working which does suggest there is perhaps a second regression going on here: https://github.com/thesofproject/linux/issues/5948 Thanks, Charles
