Perhaps > we should be using (count < 0) instead? I'm now running a kernel built with this last conditional test changed to "if (count < 0)" and sound is still working OK. Have yet to see if this eliminates the interrupt timeout messages. Perhaps a few other people might try it and see? I still don't know what to make of the earlier business with the setting of "timeout". Looks to me like something that just got overlooked in the course of a series of edits. -- Conrad J.
