tracking down xruns
Sorry, for double post, added Subject: Hi, Since discovering that the nvidia drivers do a horrible job of managing the on board laptop screen and a VGA outboard monitor I've been testing with only the laptop screen. I've been slowly removing things that suck up resources. For instance I was getting an xrun or ffado/jack crash each time the network did an update (not a dhcp lease update, I use static IP, but apparently the net drivers do some check periodically). So, I unloaded the net during recording. At this point, virtually every test, records for approximately 10 minutes gets an xrun or crash. If it gets just a xrun, it will then continue to record xrun free for as long as I run the test, so far up to an 1.5 hours. The xrun is coincident with activities that show up in the system logs. Software involved is Ubuntu 8.04, Ardour/jack/ffado. hardware: Dell dual core latop, dual Audiofire12's Any experience or ideas about what I might adjust to address this would be appreciated.

Hi again, i've done a new reboot, compared hardy's limits.conf to jaunty'one, and so hardy'one working : @audio - rtprio 99 @audio - memlock 999844 jaunty'one working but if i launch with sudo @audio - memlock 770240 @audio - rtprio 99 @audio - nice -10 so I check ubuntustudio controls, everything is ok, the limits.conf is like the controls in GUI. then i have a look to laurent un user, and see that in groups, there was no audio group. I add one, and tick laurent and root as members of this group, i've done a new reboot, and now i can launch qjackctl + ardour on RT without any xruns at 2,9ms latency !!! what is surprising is that in hardy, i check audio group presence, there's none !!! but qjackctl is available as none root ??? But now, I understand why in hardy, changing the size of allowed memory change nothing face to the ardour message which was telling me there was a limit in my system...that's normal, because laurent is not in an audio group, so limits.conf can't work... So I can't explain why in same condition hardy settings are working and why jaunty not, but after adding an audio group, and tick your account user in it, a reboot, it works perfectly... RT kernel is ok for stable release the 23 of april...

Yes I've just confirmed this. This should be fixed as of the next daily CD images for fresh installs.

Kernel-rt
Hi there, today I have made some experience with the actual kernel-rt on my notebook hd-dv6000, intel, ICH8. (ubuntu-9-04-beta). Like the other tests with the kernel-rt, the acpi-subsystem can not control the fanspeed. The fancontrol doesnt't work. The rest works nice, also the shutdown works now correct. And certainly the sound. The generic kernel works very fine and makes a stable system impression.

Re: Audio Apps as Root?
yeah, it helps. and then run all audio you want to jack as root as well. pulse audio doesn't require the root, and lets you cast across the server.

I'm agree with this, launching an apps or a daemon in root excepted for administration is not normal. Usuals programs should be launched as simple user.
