[07:55] <tomasarad> hi! have anybody problem to launch sK1 graphic app ? in my xenial ubuntu-studio sK1, not start - sorry for my bad english
[14:55] <cambriel> hi, i recently installed ubuntu studio for the first time (17.04) and am having a difficult time getting jack to function. so far I have attempted killing pulseaudio (which should not be necessary with ubuntu studio) and it was not helpful, neither was disabling DBUS. This is a relatively clean install except I  have installed some icon and theme packages, some of which have updated some other gnome packages, dockbarx, and som
[14:59] <cambriel> its probably also worth noting that ardour gives a "failed to open audio device" error as well when attmpting to connect to ALSA
[15:01] <OvenWerks> cambriel: try (in a terminal) killall -9 jackd jackdbus
[15:02] <cambriel> i killed jackdbus just now and re-opened ardour and its giving me a different error: "The audio backend was shutdown because:  ALSA I/O error."
[15:03] <OvenWerks> did you also kill jackd?
[15:04] <OvenWerks> alsa IO error? what buffer size are you using?
[15:05] <cambriel> jackd wasnt running
[15:05] <cambriel> the buffer size is "1024 samples"
[15:07] <OvenWerks> that should be fine.
[15:07] <OvenWerks> which audio IF do you use?
[15:09] <cambriel> im sorry i do not know what that means
[15:10] <OvenWerks> what audio device are you using?
[15:10] <cambriel> in ardour?
[15:10] <OvenWerks> in you r computerthat you want to use for ardour
[15:12] <OvenWerks> You might try pasting the output of cd /tmp && wget http://jackaudio.org/downloads/adevices.sh && bash ./adevices.sh
[15:12] <OvenWerks> to pastebin.com and posting the url here
[15:15] <cambriel> i just noticed that playing videos on my browser also no longer produces audio, whereas it used to. so something went wrong obviously since i have installed? im not sure what or how
[15:15] <cambriel> https://pastebin.com/6QXsEQFw
[15:16] <OvenWerks> jackd is running so it blocks the browser
[15:17] <OvenWerks> So you are using only internal audio it looks like
[15:19] <OvenWerks> you do need to stop jackd so "killall -9 jackd"
[15:21] <cambriel> oh weird i did that before and it said there was no such process. could starting ardour have started it again somehow?
[15:23] <OvenWerks> yes
[15:23] <OvenWerks> many jack aware apps will start jackd if it is not already running
[15:24] <cambriel> yeah because i'm still getting the same alsa i/o error when i try to start ardour
[15:24] <OvenWerks> :)
[15:24] <OvenWerks> It is best to run jackdbus from qjackctl right after boot.
[15:25] <cambriel> yeah and when i try to do that it does not work lol
[15:25] <OvenWerks> Running jackdbus will bridge pulse to jack so your browser will work too.
[15:26] <cambriel> qjackctl gives me all sorts of errors when i try to start it, even right after boot
[15:26] <cambriel> thats like, my main issue with ubuntu studio so far
[15:26] <OvenWerks> some of those errors may be harmless. The question is if t will start jackdbus correctly.
[15:27] <cambriel> it does not
[15:27] <OvenWerks> You can also use jack_control from the command line
[15:28] <OvenWerks> have you changed the jack server name in the qjackctl setup?
[15:28] <OvenWerks> (in advanced)
[15:29] <cambriel> I don't think so
[15:29] <OvenWerks> ok,
[15:31] <OvenWerks> what do you get if you do killall jackd jackdbus; jack_control start
[15:35] <cambriel> https://pastebin.com/f4mkQx0f
[15:37] <OvenWerks> ls -l /usr/bin/jackdbus
[15:37] <OvenWerks> What are the permissions?
[15:38] <cambriel> -rwxr-xr-x 1 root root 108952 Sep 17  2016 /usr/bin/jackdbus
[15:38] <OvenWerks> Looks right
[15:39] <OvenWerks> Are you logged in as the same user that installed?
[15:39] <cambriel> Yes
[15:39] <OvenWerks> have you tried to run ardour or jack as root? (with sudo)
[15:41] <OvenWerks> Hint, do not ever run jack as root
[15:41] <cambriel> killall jackd jackdbus; sudo jack_control start jackd: no process found [sudo] password for angel:  --- start DBus exception: org.jackaudio.Error.Generic: Failed to open server
[15:41] <cambriel> oh woops
[15:41] <cambriel> i never did try but i just tried
[15:42] <cambriel> I thought you were telling me to :(
[15:42] <OvenWerks> It almost seems like dbus is not working
[15:42] <OvenWerks> As happens it didn't work so it should be not problem.
[15:43] <OvenWerks> I am not sure why though
[15:44] <cambriel> I tried disabling it in qjackctl but it still didnt work
[15:44] <OvenWerks> the copy of 17.04 I tried did have a working dbus. I was able to run jackdbus with no problem.
[15:45] <cambriel> should I just reinstall?
[15:47] <OvenWerks> if you are going to do that, make sure the iso image you have is right. Check the md5sum
[15:47] <cambriel> how do I do that
[15:48] <OvenWerks> http://cdimage.ubuntu.com/ubuntustudio/releases/17.04/release/MD5SUMS should match md5sum ubuntustudio-17.04-dvd-amd64.iso
[15:48] <OvenWerks> (assuming 64bit
[15:51] <OvenWerks> md5sum run on the iso will take some time :)
[15:52] <cambriel> I once did the "check disk" option on the usb when I booted from it. Is that the same thing?
[15:52] <OvenWerks> should be
[15:53] <cambriel> okay, so I will go ahead and reinstall i suppose
[15:54] <OvenWerks> you are getting beyond my personal understanding of things :(  While I use dbus, I do not understand it well
[18:41] <fred1807> This is a famous example of an Alsa "normalizer" plugin made with compressor and limiter: https://paste.debian.net/plain/989208.  Please, how/where can I set/incrase buffer_size in here ?
[20:03] <studio-user533> why is this using irc instead of a forum
[20:42] <cambriel> hi. i was in here earlier because i was trying to get help with jack on a new install of ubuntu studio. i just did a completely fresh install of ubuntu studio and it is still not workingio
[20:46] <cambriel> here are the messages from qjackctl if that is helpful https://pastebin.com/1S6DS5B1
[20:46] <cambriel> its extremely frustrating that jack is just is not working out of the box for me in ubuntu stoudi
