I think you mean bug #986822, though. :) > I then moved to testing and everything broke again, for other reasons > i'm now on EndeavourOS which is arch based and the tablet is without > speakers or mic as it tries to use the HDA driver on the tablet. I found that (on Debian, at least), the catpt driver works if the IOMMU is disabled. Debian enables the IOMMU by default for all devices except Intel GPUs - I don't know about EndeavourOS, but it might be similar. You can disable the IOMMU using the option "intel_iommu=off" on the kernel command line. I reported Debian bug #1014299, and haven't gotten any response. I meant to bring it to the upstream kernel developers, but I've been distracted. :) Benjamin _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
