I've done some checking internally and I'm very suspicous that what's going on here is actually the masking of some other bug elsewhere in the system. Which CPU are the systems you're observing this on using? There is at least one special case in the current code for GPIO register readbacks in the PXA AC97 driver code and there have been a number of interoperabilty issues in that area... _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
