On a whim, I decided to extract the sound/pci/hda from vanilla 2.6.20 kernel sources and compile it under 2.6.22-rc5 (yes, I know, I probably shouldn't have done that). I had to add a typedef to patch_sigmatel.c to get it to compile. When I loaded the modules, I did *not* get the "switching to single_cmd" error, but I haven't gotten sound yet, either, probably because I'm using pieces of two different versions of ALSA. However, this suggests to me that perhaps there is a problem with the hda_intel driver, and not necessarily an ACPI problem. I'm going to keep working on this, as much as I can understand right now. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
