> (CCed to alsa-devel) I sent this issue to alsa mailist 6 days ago but I supouse that hit the spam filter. Even I published an alsa-info http://www.alsa-project.org/db/?f=cb6745b6d0acdb5d9375096ec8dc008f6ff49cd7 When I read the wiki about reporting bugs, I understood that kernel related bugs goes to bugzilla.kernel.org and user-land bugs goes to the devel mail-list. So I supouse that I should sent this issue to the bugzilla as it's considered a kernel bug > Well, could I request you to gather information of packet sequence? Here is the trace of packets: https://drive.google.com/file/d/0Bz44Dr5G2FeJSXBHMzc5WTFmOWs/view?usp=sharing The trace includes the opening of alsa device and playing a sine wave for 30 seconds My linux box has two firewire ports I don't know the details about the host controller but could be feasible sniff the connection between the other computer with official drivers and the DAW? Could that be useful? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
