Hello to every member on this forum
It is my first post :-) Im Arek from Poland.
First of all thank you Glen for wonderfull job and making AVlinux, especially avl 4.0 - its great !
I uses AVlinux since v 2.0 on my first laptop IBM X31 and now I have Lenovo X60 and first I jump into v3.1 and now I'm on 4.0
My audio interface is Echo Audiofire4 and sessions lands on external USB 2.5" HDD.
After upgrade to X60 the only problem were XRUNS.
I have struggled with it many days and finally I think I have solution which works for me and I hope will be working for someone else.
After reading many posts on many forums I have found post by user @thorgal an Ardour forum.
@thorgal on Ardour forum said that hald can do troubles and it seems to be right in my case
http://ardour.org/node/2465 (the one before last)
Before that solution appear I had XRUNS which was not XRUNS :-)
It was a sudden stop and moment of silence while Ardour was playing session. In Qjackctrl appear XRUN count - see image - Ardour don't mark that as XRUNS even if I selected option in menu.

When I read @thorgal suggestion about hald I simply wrote in terminal "sudo /etc/init.d/hal stop" and restart jackd and Ardour nad NO MORE XRUNS and moments of silence :-)
A few days I havn't any job in Ardour and before today there was update of many packages.
Among this it is:
libraw1394-11, libraw1394-dev - on my installation CD is version 2.0.5-1 and latest is 2.0.5-2
Few days before I have updated this library too, and today XRUNS comeback and I WAS MMMMAAADDDDD ! believe me :-(
I have done clean install again and do not upgraded this library.
Every thing works fine, no more XRUNS.
It seems that some thing is wrong with it.
regards
Arek
