Hey Cameron, I did apply the patch against kernel 6.2.2 for the 14ACN6. There was sound from the 2 tweeters as before the patch was applied but still I don't know if the 2 woofers are actually active? Not sure what the best way to find out if woofers are working. Is there anything I can do with speaker-test? But I'll try to compare before and after patch.
I was going to try to sniff the verbs for this laptop but the problem is that the audio controllers are on the same IOMMU groups as radeon gpu, pci, usb and psp. So I cannot not passthrough the audio devices without ACL override.
