The fact that this option is a) present, and b) functional seems to indicate that at least one person knows either why Alsa locks up, or how a lock-up can be avoided. Some digging around in the sources seems to indicate that audioalsa.C contains the code for this; correct me if I'm totally wrong, but this code seems to process interrupt_workaround, the variable controlled through the GUI option. But lacking both sufficient C programming skills and a more complete overview of Cinelerra, I can't really trace what exactly happens here. The comments suggest some dirty tricks and/or trial-and-error-programming, though. > Or am I wrong?

It's too much like "this appears to work but don't ask me how", which is not good. Then again, this isn't exactly a pressing matter, merely annoying (although almost every newbie stumbles upon this one).
