[19:42] <crimzon> Hi Everyone! I could use some help if anyone is up for a JACK/Audio issue?
[19:58] <holstein> crimzon: hey
[19:58] <holstein> whats up?
[19:59] <crimzon> hi
[19:59] <crimzon> well, jack is failing to start
[19:59] <holstein> has it ever started?
[19:59] <crimzon> No, new build. Ubuntu Studio 10.04  AMD SB 850 Ati Chipset
[19:59] <holstein> OK
[19:59] <holstein> internal card?
[20:00] <crimzon> ya
[20:00] <holstein> RT kernel?
[20:00] <crimzon> it says preempt, is that the same thing?
[20:00] <holstein> run uname -a in a terminal just to make sure
[20:00] <holstein> crimzon: not to JACK
[20:00] <holstein> AFAIK
[20:01] <holstein> crimzon: run sudo qjackctl
[20:01] <holstein> and go into the 'setup'
[20:01] <holstein> and uncheck the 'realtime' check box
[20:01] <holstein> and see if it starts as su
[20:01] <holstein> crimzon: check the latency down in the right corner too
[20:02] <holstein> an dmake sure its nothing ridiculous
[20:02] <holstein> 20ms or more should be safe
[20:03] <crimzon> Hmmm. I don't see setup in the qjackctl
[20:03] <holstein> let me get a screenshot link
[20:03] <holstein> so we know we're talking about the same thing
[20:04] <holstein> http://qjackctl.sourceforge.net/qjackctl-ss1.html
[20:04] <holstein> crimzon: check that out ^^
[20:04] <holstein> the first screenshot
[20:04] <holstein> click on 'setup'
[20:04] <holstein> thats what you should see when you run sudo qjackctl
[20:05] <crimzon> lol, I'm sorry. I found it. Wow. I've been staring at this stuff too long.
[20:05] <holstein> crimzon: i totally understand
[20:05] <holstein> im doing the same thing
[20:05] <holstein> setting up a new install on a better box i had donated to me
[20:05] <holstein> after a while, it just all looks the same ;)
[20:06] <holstein> ANYHOW, whats the latency reading down in the lower right?
[20:07] <crimzon> Man, I can't get win7 to dual boot for the life of me. But that's another issue. Trying to use MDADM for a software raid5, but windows just can't let it do, keeps nuking MBRs on all disks... it's odd.
[20:07] <crimzon> whatever, 69ms latency
[20:07] <holstein> cool
[20:07] <holstein> that'll be fine for testing purposes
[20:07] <holstein> uncheck that 'realtime box'
[20:07] <crimzon> What should I be able to get that down to?
[20:08] <holstein> save
[20:08] <crimzon> ya, unchecked
[20:08] <holstein> and try starting it
[20:08] <holstein> crimzon: with an internal card
[20:08] <holstein> and preemtive kernel
[20:08] <holstein> and no RT set here
[20:08] <holstein> i would think under 30
[20:08] <holstein> maybe under 20 ?
[20:08] <holstein> depends really
[20:09] <holstein> crimzon: you can try getting the RT kernel and checking this box
[20:09] <crimzon> I have a PCI Audigy 2, and I could maybe compile an RT for my system. I'd like to get it under 10 for recording purposes later.
[20:09] <holstein> you might be able to get close to 10
[20:09] <crimzon> not installed mind you
[20:10] <holstein> does is start as root?
[20:10] <holstein> and not complain?
[20:10] <crimzon> Seems to be putting along, message readout is all XRUN callback 26-27
[20:11] <holstein> cool
[20:11] <holstein> yeah, lost of things can cause that
[20:11] <holstein> might want to look at your IRQ's
[20:11] <holstein> later
[20:11] <holstein> ANYWAY
[20:11] <holstein> hit the stop button
[20:11] <holstein> and close Qjack
[20:12] <holstein> and open it back up as normal user
[20:12] <holstein> double check the settings, and see if it starts and acts similar
[20:13] <crimzon> looks happy. same output
[20:13] <holstein> crimzon: COOL
[20:13] <holstein> so your up and running
[20:13] <holstein> need to trouble shoot those xruns
[20:13] <crimzon> So I might have sound now? YEA!!!!
[20:14] <holstein> first place i look is cat /proc/interrupts
[20:14] <crimzon> Ok, where should i read about that?
[20:14] <crimzon> k
[20:14] <holstein>  21:   31880039   IO-APIC-fasteoi   ehci_hcd:usb1, uhci_hcd:usb3, sata_via
[20:14] <holstein> thats a line from mine
[20:14] <holstein> you want your sound card off by itself idealy
[20:14] <holstein> ideally*
[20:14] <holstein> sometimes you can set this in the bios, sometimes not
[20:15] <holstein> crimzon: also, just relaxing the JACK settins
[20:15] <holstein> increasing frames/period and periods/buffer
[20:15] <holstein> crimzon: hell
[20:16] <holstein> getting the RT kernel and checking that box can help too
[20:16] <crimzon> ;-p
[20:16] <holstein> you might want to try that first
[20:16] <holstein> thats easy enough
[20:16] <crimzon> 16:      52020         18        396        756   IO-APIC-fasteoi   HDA Intel
[20:16] <holstein> check out #opensourcemusicans too
[20:17] <holstein> if you need more tweaking advice
[20:17] <holstein> crimzon: thats probably OK
[20:17] <crimzon> 19:          0          0         33         55   IO-APIC-fasteoi   HDA Intel
[20:17] <holstein> not bad having 2
[20:17] <holstein> you could look in your bios next reboot
[20:17] <crimzon> one is for the HDMI built in
[20:17] <holstein> and see if you can get the sound off on its own
[20:17] <crimzon> make sure audio has it's own IRQ?
[20:18] <crimzon> k
[20:18] <holstein> but that looks acceptable
[20:18] <crimzon> I could try this Soundblaster, see if it performs better. I keep getting a random popping sound in my left or right speaker.
[20:19] <holstein> yeah, im not a fan of the creative gear personally
[20:19] <holstein> but, its worth a try
[20:20] <crimzon> Thank you so much for your help
[20:20] <holstein> anytime :)
[20:20] <holstein> good luck
[20:20] <crimzon> I can't believe it was that simple!!!
[20:20] <holstein> hehe
[20:21] <holstein> OH yeah
[20:21] <holstein> for dual booting
[20:21] <holstein> http://gag.sourceforge.net/
[20:21] <holstein> check that bootloader out
[20:22] <holstein> AFAIK you dont have to install it to use it
[20:22] <crimzon> :-[
[23:25] <osmodivs> Does Ubuntu studio comes with YafaRay?
[23:25] <osmodivs> Does Ubuntu studio comes with YafaRay?'
[23:25] <osmodivs> Or some other renderer for Blender?
[23:26] <osmodivs> I am downloading the "alternate" version, whatever that means
[23:26] <osmodivs> 1 hour to go
