Re: [Melys-devel] Using external MIDI port

[Steve R. <st...@pa...>]

Your problem looks similar to ALSA bug number 619:

	http://www.alsa-project.org/cgi-bin/bugs/00_INCOMING?id=619;user=guest;selectid=619

Although the bug report is saying it happens on output, while you are
seeing a problem on input.

I also have a Live! but I do not see this problem on either input
or output.  I am using a version of ALSA from CVS just after 0.5.6,
so the problem may have been fixed.

Not being able to restart the driver is definitely an ALSA error.
Have a look in /var/log/messages and see if there is an Oops
message written when the problem occurs.

You can use the alsa-lib/test/seq program to receive MIDI
events and print out them out:

	seq decoder 64.0
