| Capitaine | hi folks, i need some help to setup Jack from fresh install | 16:04 |
|---|---|---|
| Capitaine | https://paste.ubuntu.com/p/d7V385nD4b/ | 16:23 |
| OvenWerks | It looks like something else is using the device already. | 16:31 |
| Capitaine | to start... anybody know what should be err = ? and where to change it's value? | 16:31 |
| OvenWerks | I would suggest try killall -9 jackd jackdbus | 16:31 |
| OvenWerks | then try starting jack again | 16:32 |
| OvenWerks | Note that many jack aware programs will start jackd on their own if jack is not running. This jackd may not stop once the program has stopped | 16:33 |
| Capitaine | OvenWerks, okay. it says no process found. | 16:34 |
| OvenWerks | hmm, ok run: | 16:34 |
| OvenWerks | cd /tmp && wget http://jackaudio.org/downloads/adevices.sh && bash ./adevices.sh | 16:35 |
| OvenWerks | (all one line) and paste the output. | 16:35 |
| OvenWerks | That should tell what application is using your device | 16:35 |
| Capitaine | https://paste.ubuntu.com/p/KCgy7jBVf3/ | 16:37 |
| OvenWerks | hmm it just says pulse which should give up it's device when asked. | 16:38 |
| OvenWerks | do you have the bottom half of the output? (Part II?) | 16:40 |
| Capitaine | one process.. qjackctl ... | 16:41 |
| OvenWerks | ok | 16:41 |
| OvenWerks | just as a quick check.. try jack_control ds alsa dps capture none dps playback none | 16:43 |
| OvenWerks | jack_control dps device hw:PCH dps rate 48000 | 16:44 |
| Capitaine | driver : alsa capture : none record: none | 16:44 |
| OvenWerks | jack_control dps period 1024 dps nperiods 2 start | 16:45 |
| OvenWerks | those three commands | 16:45 |
| OvenWerks | then jack_lsp | 16:45 |
| OvenWerks | jack_lsp should show system:capture_1 | 16:47 |
| OvenWerks | and system:playback_1 lines | 16:48 |
| OvenWerks | (probably 2 each) | 16:48 |
| Capitaine | https://paste.ubuntu.com/p/nt7xkx7ssZ/ | 16:49 |
| OvenWerks | cool, so jack is running | 16:50 |
| Capitaine | okay... do i have to do it everytime? | 16:50 |
| OvenWerks | if you restart qjackctl it should show that jack is running and you should be able to open the connects window | 16:50 |
| OvenWerks | you shouldn't | 16:51 |
| OvenWerks | Have you looked at using ubuntustudio-controls? (if you are using 18.04 it is not that far along yet) | 16:52 |
| Capitaine | i got fresh install with update from last stable release las week | 16:53 |
| OvenWerks | -controls can start jack at session start | 16:54 |
| OvenWerks | -controls can also start stop jack any time | 16:57 |
| OvenWerks | patchage gives a good way to connect jack clients too | 16:57 |
| OvenWerks | if your ubuntustudio-controls does not have the Audio Setup tab, you can install the new one from: https://launchpad.net/~ubuntustudio-dev/+archive/ubuntu/autobuild | 16:58 |
| OvenWerks | This is the one that comes with 18.10 | 16:59 |
| OvenWerks | If you are going to use qjackctl, stay away from the advanced tab :) Almost any setting made in the advanced tab will cause trouble. | 17:03 |
| OvenWerks | to reset qjackctl rm ~/.config/rncb.org/QjackCtl.conf | 17:05 |
| Capitaine | ok. if i don't do so it will keep that actual configuration? | 17:09 |
| OvenWerks | the configuration will be saved from application start to application start | 17:10 |
| Capitaine | okay what app would be good to start with? | 17:12 |
| OvenWerks | There are two common things people do in qjackctl that cause trouble: change the server name to anything other than (default) or try to use two different devices for input and output. (like computer speakers for out put and USB audio box for input) | 17:14 |
| OvenWerks | if you stay away from that qjackctl will work fine for starting jack | 17:14 |
| OvenWerks | The only thing to remember is to start jack with qjackctl before you start any app that uses jack | 17:15 |
| OvenWerks | Or did you mean what app would be good to rty audio out with? | 17:17 |
| Capitaine | ok... and ... if i need the input from a usb microphone to output in the speaker i must connect it with patchage right? | 17:18 |
| OvenWerks | no you need to use zita-ajbridge | 17:18 |
| OvenWerks | use ubuntustudio-controls will do that for you. | 17:18 |
| OvenWerks | ubuntustudio-controls is under system in the menu. | 17:20 |
| Capitaine | and if i want to add some beat from lmms to the usb microphone and output them both in real time i have to ... ? | 17:20 |
| OvenWerks | use ubuntustudio controls | 17:21 |
| OvenWerks | your usb mic will just show up in jack | 17:21 |
| OvenWerks | it will not show up as "system" but as the device name | 17:22 |
| Capitaine | i have to make a user for every item and then add it to realtime user | 17:23 |
| Capitaine | right? | 17:23 |
| OvenWerks | opps! you have the old one | 17:23 |
| OvenWerks | get the new one from https://launchpad.net/~ubuntustudio-dev/+archive/ubuntu/autobuild | 17:23 |
| OvenWerks | just add the PPA and it should be upgradable | 17:24 |
| OvenWerks | or you can DL the deb directly and install with dpkg | 17:25 |
| OvenWerks | (or apt) | 17:25 |
| Capitaine | ok... | 17:26 |
| OvenWerks | direct download is https://launchpad.net/~ubuntustudio-dev/+archive/ubuntu/autobuild/+files/ubuntustudio-controls_1.7+git-0~201810210006~ubuntu18.04.1_all.deb | 17:26 |
| Capitaine | ok. done. | 17:35 |
| OvenWerks | When you open it the window should be much bigger | 17:36 |
| OvenWerks | There are two tabs | 17:36 |
| Capitaine | yes it is... | 17:36 |
| OvenWerks | in Audio Setup, set jack master to PCH,0,0 | 17:37 |
| Capitaine | system tweak and audio setup | 17:37 |
| OvenWerks | then make sure the check box at the bottom for Bridge USB devices to jack when plugged in is checked | 17:38 |
| OvenWerks | your usb mic should now show up in qjackctl connections or patchage | 17:38 |
| Capitaine | ok. | 17:39 |
| OvenWerks | Be carefule with qjackctl as I think it defaults to stopping jack when qjackctl is exited. | 17:39 |
| Capitaine | ok so i don't close it. | 17:40 |
| OvenWerks | This can be changed in qjackctl setup in the Misc tab by unchecking: start jack audio server on application startup and unchecking Stop jack audio server on application exit | 17:41 |
| Capitaine | ok. | 17:43 |
| Capitaine | then i need to setup zita-mu1's input... | 17:46 |
| Capitaine | let's say number one input as the microphone and number2 input as lmms | 17:48 |
| OvenWerks | So you are using MU1 as a mixer then? | 17:49 |
| * OvenWerks had not thought of that | 17:49 | |
| OvenWerks | I don't think that will mix the two sources though, it looks like it switches from one to the other | 17:50 |
| OvenWerks | The only app that comes with studio that mixes (aside from Ardour) is idjc | 17:51 |
| OvenWerks | (under internet) | 17:51 |
| Capitaine | ok | 17:52 |
| OvenWerks | there is jack-mixer, dbmix (I don't know if it does jack though), | 17:55 |
| OvenWerks | mixxx is there also | 17:55 |
| OvenWerks | Actually jack-mixer looks good | 17:58 |
| OvenWerks | it has meters and can be configured to as many chanels as you like | 18:00 |
| * OvenWerks is going to suggest adding this to Studio for 19.04 | 18:00 | |
| OvenWerks | Capitaine: I would install jack-mixer and use that. | 18:05 |
| Capitaine | did it... do you know how to setup the channel from lmms ? | 18:15 |
| OvenWerks | I am not sure what you mean | 18:17 |
| OvenWerks | in jack mixer you add a new input... name it LMMS | 18:17 |
| OvenWerks | then in qjackctl connection connect the output of lmms (capture) to the input of jack-mixer (playback) | 18:18 |
| OvenWerks | The meter in jack-mixer should show the audio from lmms | 18:19 |
| OvenWerks | I am not familiar with lmms though. So I don't know how to get sound from it. Ah, lmms starts with it's outputs connected to system:playback. So disconnect that and reconnect to jack-mixer lmms L and R | 18:21 |
| OvenWerks | you USB mic may be only 1 channel in which case I would connect it to both the Mic L and R | 18:22 |
| Capitaine | ok. thanks a lot man. should be good now to at least start ... | 18:26 |
| OvenWerks | You're welcome, enjoy | 18:27 |
| craigbass76 | Any idea why I can see an input registering signal (Volume Control -> Input Devices -> Line In) but don't hear anything. | 20:45 |
| OvenWerks | craigbass76: more info? Which application are you using? | 20:46 |
| OvenWerks | Jack or not? | 20:46 |
| craigbass76 | Hah... That was dumb. Yes, I could hear it if I was in Ardour with jack running. I just read something about loopback. So I got into alsamixer, enabled a loopback that I saw there, and now I can hear. | 20:49 |
| craigbass76 | I've got latency down quite a bit in Ardour, but it's still not quite like hearing it live | 20:50 |
