UncleJedhello...is there a more specific channel for audio help for studio, or is this kind of the general place for it all?00:45
holsteinUncleJed: this is the place..00:46
UncleJedIn particular I just need a little direction for configuring my qjackctl....having issues with video freezing when jack is on.00:47
holsteinUncleJed: relax the latency settings00:47
UncleJedwow...i hope it's that easy! lol. I'm pretty new to linux - so have been doing A LOT of google-ing and learning a ton! I'll give that shot.00:48
holsteinrelax it a lot00:49
holsteinlike, 50+ ms latency, and test00:49
holsteinyou are likely just expecting too much from the hardware00:49
holsteinyou can, as i have found, try different GPU drivers.. this can help as well00:49
holsteincan also make it drastically worse00:49
UncleJedhaha...ok. Just as an FYI. I'm using an M-Audio Fastrack Pro box and followed some guy's direction on manually editing the driver file..so it's all nuts and bolts.00:50
UncleJedI'll try those things. Thanks for your help holstein!00:50
holsteinmanually editing what driver file?00:50
holsteinyou shouldnt have a driver for that device, necessarily00:50
holsteinshould "just work". with the kernel drivers included00:51
UncleJedit's been a few months since i did it..let me find the page. just a sec.00:51
holsteinanyways, if you want to be certain, and isolate your changes, you can use a live iso00:51
holsteinthis will remove any customizations you have done from the equation without breaking your current setup00:51
UncleJedhttp://joegiampaoli.blogspot.com/2011/06/m-audio-fast-track-pro-for-debian-linux.html00:52
holsteinyou really shouldnt need to do anything like that00:53
holsteinand you dont have an rt kernel00:53
holsteinif you want, test with the live iso, as i said. and see if its "better"00:53
holsteintry the latest 15.04 live iso, and see00:53
holsteinalso, i like to use the AVlinux live iso, since its a much older kernel00:53
UncleJedok - will give it a shot. Thanks again!00:53
holsteinthis will let you see what is possible without breaking anything you current have, assuming just relaxing the latency settings doesnt address what you want00:54
UncleJedokie-doke00:54
UncleJedwell that didn't work. That walk-through had me change a lot of things. And I had toyed with a bunch of stuff before that. I think, given my inexperience with linux, I may just wipe the drive and start over.03:03
UncleJedIt's just weird. Videos were working fine before I messed with things in the system config, but Ardour would not recognize the m-audio box (or jack wouldn't). that's what led me to the walk-through. Now audio works great through the box for working with Ardour, but as soon as I try playing video with other software (firefox or the default video player) it freezes. Furthermore, if I stop the jack service, I get audio from them, b03:09
UncleJedut it sounds extremely peaked - like input levels are over the top. and it's extremely loud. I have to turn all my knobs almost all the way down - and it still sounds the same.03:09
UncleJed...guess that's what I get for jackin' with jack. lol03:10
UncleJed...off to bed for now.03:10
UncleJedwait...noticed you said I don't have RT kernel. Guess I thought that was part of the point in getting ubuntu studio - that it WAS real-time. *scratches head* I've got a lot to learn.03:53
Unit193!info linux-image-lowlatency03:54
ubottulinux-image-lowlatency (source: linux-meta): lowlatency Linux kernel image. In component main, is optional. Version 3.16.0.34.35 (utopic), package size 2 kB, installed size 29 kB03:54
UncleJedIf I understand right, what you just indicated was the it's an optional install with studio. How do I check to make sure I did that when I installed everything? It's been so long, i can' remember.04:08
UncleJedoh wait....I think i can see it with syanptic04:09
UncleJedlooks like i have 3.13.0.49.5604:11
UncleJed...alright i have to get to bed now.....will continue later. thanks everyone for your patience and input. :-)04:12
OvenWerksUncleJed: Studio comes with lowlatency kernel04:18
OvenWerksnot RT04:18
OvenWerksbut it includes most of what RT does.04:18
OvenWerksThe main good thing about lowlatency is that the graphics drivers all still work.04:20
OvenWerksI have gotten stable audio operation down to .66ms with it. (32 samples per buffer)04:21
OvenWerksWith a USB audio IF you should still be able to get to 128 or below. (128 with two channels, less with more)04:23
UncleJedah....gotcha. alright. think i'm just going to blast HDD and start over then. I've messed with a lot of stuff i have no idea how to reverse.04:29
