[07:55] hi! have anybody problem to launch sK1 graphic app ? in my xenial ubuntu-studio sK1, not start - sorry for my bad english [14:55] 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] 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] cambriel: try (in a terminal) killall -9 jackd jackdbus [15:02] 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] did you also kill jackd? [15:04] alsa IO error? what buffer size are you using? [15:05] jackd wasnt running [15:05] the buffer size is "1024 samples" [15:07] that should be fine. [15:07] which audio IF do you use? [15:09] im sorry i do not know what that means [15:10] what audio device are you using? [15:10] in ardour? [15:10] in you r computerthat you want to use for ardour [15:12] You might try pasting the output of cd /tmp && wget http://jackaudio.org/downloads/adevices.sh && bash ./adevices.sh [15:12] to pastebin.com and posting the url here [15:15] 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] https://pastebin.com/6QXsEQFw [15:16] jackd is running so it blocks the browser [15:17] So you are using only internal audio it looks like [15:19] you do need to stop jackd so "killall -9 jackd" [15:21] oh weird i did that before and it said there was no such process. could starting ardour have started it again somehow? [15:23] yes [15:23] many jack aware apps will start jackd if it is not already running [15:24] yeah because i'm still getting the same alsa i/o error when i try to start ardour [15:24] :) [15:24] It is best to run jackdbus from qjackctl right after boot. [15:25] yeah and when i try to do that it does not work lol [15:25] Running jackdbus will bridge pulse to jack so your browser will work too. [15:26] qjackctl gives me all sorts of errors when i try to start it, even right after boot [15:26] thats like, my main issue with ubuntu studio so far [15:26] some of those errors may be harmless. The question is if t will start jackdbus correctly. [15:27] it does not [15:27] You can also use jack_control from the command line [15:28] have you changed the jack server name in the qjackctl setup? [15:28] (in advanced) [15:29] I don't think so [15:29] ok, [15:31] what do you get if you do killall jackd jackdbus; jack_control start [15:35] https://pastebin.com/f4mkQx0f [15:37] ls -l /usr/bin/jackdbus [15:37] What are the permissions? [15:38] -rwxr-xr-x 1 root root 108952 Sep 17 2016 /usr/bin/jackdbus [15:38] Looks right [15:39] Are you logged in as the same user that installed? [15:39] Yes [15:39] have you tried to run ardour or jack as root? (with sudo) [15:41] Hint, do not ever run jack as root [15:41] 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] oh woops [15:41] i never did try but i just tried [15:42] I thought you were telling me to :( [15:42] It almost seems like dbus is not working [15:42] As happens it didn't work so it should be not problem. [15:43] I am not sure why though [15:44] I tried disabling it in qjackctl but it still didnt work [15:44] the copy of 17.04 I tried did have a working dbus. I was able to run jackdbus with no problem. [15:45] should I just reinstall? [15:47] if you are going to do that, make sure the iso image you have is right. Check the md5sum [15:47] how do I do that [15:48] http://cdimage.ubuntu.com/ubuntustudio/releases/17.04/release/MD5SUMS should match md5sum ubuntustudio-17.04-dvd-amd64.iso [15:48] (assuming 64bit [15:51] md5sum run on the iso will take some time :) [15:52] I once did the "check disk" option on the usb when I booted from it. Is that the same thing? [15:52] should be [15:53] okay, so I will go ahead and reinstall i suppose [15:54] you are getting beyond my personal understanding of things :( While I use dbus, I do not understand it well [18:41] 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] why is this using irc instead of a forum [20:42] 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] here are the messages from qjackctl if that is helpful https://pastebin.com/1S6DS5B1 [20:46] its extremely frustrating that jack is just is not working out of the box for me in ubuntu stoudi
