[10:01] <Cavern> Hello, I seem to have stuttering with my graphics. The thing is when I start my computer everything is fine but there is almost always a moment when stuttering appears as I watch a video (even in 480p) or even with basic waveform display in Mixxx! I did a glxinfo and my openGL is 1.4... Not really a ubuntustudio problem I'm aware since I had the
[10:01] <Cavern> problem with Trisquel 8 as well but couldn't find answer on the web.
[10:02] <Cavern> *seem=really do
[22:13] <andee2233> Hello all, is this the right place to ask for tech support?
[22:14] <OvenWerks> Yes for ubuntustudio specific questions
[22:16] <andee2233> Of course. I'm having trouble getting my PCI firewire card to show up in the 1394 devices panel. It worked before, now I did a install of ubuntu studio on Kubuntu and it's gone, hence, I can't use my audio interface. :(
[22:16] <andee2233> hwinfo sais this about my fw card
[22:17] <andee2233>  Driver Info #0:    Driver Status: ohci1394 is not active    Driver Activation Cmd: "modprobe ohci1394"
[22:17] <Eickmeyer> !paste
[22:17] <andee2233> ah, sorry, I remember now.
[22:17] <OvenWerks> andee2233: FW is my least informed area just now :)
[22:18] <andee2233> https://paste.ubuntu.com/p/TddVXWz2GW/
[22:18] <andee2233> It's the new vs old firewire driver stack that's giving me trouble for the past week or so.
[22:18] <OvenWerks> I have just gotten a FW interface... but the PCIe card I got to go with it does not show the device.
[22:19] <andee2233> Same here, my interface is a Focusrite Saffire pro 14
[22:20] <OvenWerks> that paste shows the pci card but no device.
[22:20] <andee2233> If I plug in the interface or not, it's the same output in hwinfo
[22:21] <OvenWerks> There are actually 3 FW stacks to play with. There is the oldest one the ffado one and the ALSA one. The Alsa one is enabled by default.
[22:21] <andee2233> gscanbus shows this https://paste.ubuntu.com/p/5jxBSRG9kx/
[22:21] <andee2233> I'm not sure how to check / change that.
[22:22] <OvenWerks> I think if the ALSA fw module for the fw interface is being used then it desn't show up anywhere else.
[22:23] <OvenWerks> but in my case I do not see a new ALSA device either
[22:23] <OvenWerks> (using aplay -l)

[22:25] <andee2233> https://paste.ubuntu.com/p/W647NX2crb/
[22:25] <OvenWerks> Wow you are doing better than I am.
[22:25] <andee2233> better but wrong :D
[22:29] <OvenWerks> what does lsmod |grep fire
[22:29] <OvenWerks> give?
[22:29] <OvenWerks> (I get three lines
[22:33] <andee2233> Same https://paste.ubuntu.com/p/dDvQrMJYCT/
[22:33] <OvenWerks> So ALSA has not found it and grabbed it.
[22:34] <OvenWerks> ]When did it last work? (Ubuntu release, kernel?)
[22:36] <andee2233> Latest kubuntu with ubuntu studio applied on it, latest lowlatency kernel. I'm not really sure what got it working, but it was showing up at some point in the 1394 devices panel .After trying to get my audio interface to get recognized as well, I must've done something and it gave some grub error, but the firewire card was present just before that.
[22:36] <andee2233> Hardware wise it's all functional as it's been tested to work on Windows 7 and 10.
[22:36] <OvenWerks> So it did work with kububtu 19.10?
[22:37] <andee2233> Yes.
[22:37] <OvenWerks> Ah, great to know. I am feeling better already. I will have to do some testing.
[22:37] <andee2233> Recognized the fw card as it's actual chipset name and everything.
[22:37] <andee2233> Now it just sais S400 linux firewire.
[22:38] <andee2233> And apart from hwinfo, nothing seems to recognise the fw card.
[22:38] <OvenWerks> So it could even be the low lat kernel (though I don't see how)
[22:38] <andee2233> *confused*
[22:38] <OvenWerks> me too
[22:39] <OvenWerks> Like I said, firewire is completely new to me. I will install kubuntu and see if I can see anything on my setup. (or if I really do need to order another PCIe FW card)
[22:41] <andee2233> That's very unlikely as these things are so old that they most probably have their drivers loaded on smart fridges nowadays.
[22:43] <OvenWerks> It could have come borked... or the cable is. I will order a cheaper one (the last was with a TI chip) with a VIA chip (also supposed to work)
[22:43] <andee2233> I got both, a VIA onboard and a TI on the PCI
[22:44] <OvenWerks> A PCI card may be something for me to try as well.
[22:44] <andee2233> The onboard one wouldn't work even in windows, anything I tried. I got the PCI one and it detected immediately in windows, got the focusrite program, ran it, worked, all good there, so at least I'm certain I'm not chasing my own tail by trying to software debug a hardware issue.
[22:45] <OvenWerks> I do have one spare slot (and if I can get it to work I could remove one of the cards I have)
[22:45] <OvenWerks> good.
[22:46] <OvenWerks> Have you tried the generic kernel since installing Studio on top of kubuntu?
[22:46] <andee2233> Nope, not sure how to do that.
[22:46] <andee2233> I thought they get replaced. (disclaimer: I've last used ubuntu at version 7)
[22:47] <OvenWerks> grub menu there is a sub menu two entries down that shows all kernels installed.
[22:47] <OvenWerks> Or it may even show up as the second entry.
[22:47] <andee2233> Right, so reboot, and boot on generic. Understood.
[22:47] <OvenWerks> ya.
[22:49] <andee2233> Be right back.
[22:49] <OvenWerks> k
[22:55] <andee2233> Back.
[22:55] <andee2233> Still not showing up in generic kernel.
[22:56] <OvenWerks> so maybe someother difference from k to studio.
[23:02] <andee2233> The one last thing I didn't try is actually installing ubuntu studio clean and see if the problem persists. :-?
[23:02] <andee2233> Just KX studio and I've applied the package to kubuntu
[23:03] <Eickmeyer> !kxstudio
[23:03] <OvenWerks> kx studio is another beast all together
[23:03] <andee2233> Aw.
[23:04] <Eickmeyer> andee2233: If at any point KXStudio has touched your installation, you need to seek support in #kxstudio. We can't support ith here.
[23:04] <OvenWerks> Cadence does weird wild and even wonderful things... but I do not know them.
[23:04] <andee2233> It's been formated since. 4 - 5 days ago.
[23:04] <andee2233> So nothing of Kx studio is present anymore.
[23:04] <Eickmeyer> andee2233: Did you keep your home folder?
[23:05] <andee2233> Nope. Total wipe on each install.
[23:05] <Eickmeyer> OK, then you're good.
[23:05]  * Eickmeyer heads back to lurking
[23:05] <OvenWerks> so it worked on the last kxstudio (14.04). Did it actually work on kubuntu 19.10 before adding the Studio metas?
[23:06] <andee2233> It worked after adding the studio metas.
[23:06] <andee2233> I've been kicking myself for 3 days for not logging everything I did to get it to run.
[23:06] <OvenWerks> (I am on Studio 18.04 so not up to date at all)
[23:19] <andee2233> Should I try uninstalling alsa and maybe blacklisting snd_dice?
[23:21] <OvenWerks> I am basically out of answers.
[23:21] <OvenWerks> If snd_dice is not being loaded now, then blaclisting or removing it will not make a difference
