Hello! We're trying to use ALSA for the purpose of grabbing sound bytes into java using the JavaSound API directly. However, sometimes we experience that the read() access to the device blocks infinitely. Then, also when we access the GUI controls of sound in the desktop, they sometimes freezes, and sometimes pops up strange error messages. Is this due to some default setting on ALSA allowing only one application to access the hardware at a time? I have studied the Howto sections in alsa.opensrc.org and found this statement "ALSA drivers, as a rule, will support sharing if the hardware supports it. The ALSA library supports sharing even if the hardware does not support it, but this requires some explicit configuration" in http://alsa.opensrc.org/AlsaSharing. Could this be the reason why my application/configuration GUIs hangs? It's not possible for me to create a recipe on how to recreate this problem, it seem to happen in an unpredictable fashion, making ALSA too unstable for me to use as a production system, which is very disappointing indeed. I'm also quite surprised that Ubuntu, which is told me to be one of the most advanced Linux distros is shipped with configuration GUIs that freezes like this. PS: I've tested both on Ubuntu Edgy and Dapper, and see the same problem both places. I can give more details on hardware if required.
