| den | Hi can any of you help me with a Jack issue I'm having? | 14:40 |
|---|---|---|
| coelebs | what's the issue? | 14:41 |
| den | I have my guitar hooked up to my PC, and I'm pretty sure I've got Rakarrack set up through Jack properly, but it seems as though my guitar is still not getting through to Rakarrack. | 14:42 |
| coelebs | let's see | 14:43 |
| coelebs | mine works out of the box | 14:43 |
| coelebs | now that i hooked up mic to mic in | 14:44 |
| coelebs | maybe you got line in selected | 14:44 |
| den | What do you mean? | 14:44 |
| coelebs | open terminal and alsamixer | 14:44 |
| den | Alright. | 14:45 |
| coelebs | press F4 and navigate to input source | 14:45 |
| den | Okay. | 14:45 |
| coelebs | you can choose with up/down arrows | 14:45 |
| den | Out of line, front, and rear mic, the only sound I get at all come from Line. | 14:46 |
| coelebs | do you have laptop? | 14:46 |
| den | No it's a desktop. | 14:46 |
| coelebs | and you turned the volume knob on guitar? | 14:47 |
| den | Yes. | 14:47 |
| coelebs | let's take qjackctl open next | 14:47 |
| coelebs | you might want to keep alsamixer open | 14:48 |
| den | I already have qjackctl open. | 14:48 |
| holstein | den: does jack work otherwise? | 14:48 |
| coelebs | system goes to rakarrack and rakarrack goes to system in connection panel? | 14:49 |
| coelebs | and jack is running? | 14:49 |
| den | Yes, and yes. | 14:49 |
| holstein | plugging a guitar straight into any sound card like that may not work on a simple impedance level.. | 14:49 |
| den | I've had it working before on Ubuntu 13.12 but it stopped when I installed 14.04. | 14:50 |
| holstein | the line in's are not for instruments | 14:50 |
| holstein | den: you mean, on 13.10? | 14:50 |
| den | Yeah. | 14:50 |
| den | I have no idea why it isn't working now. | 14:52 |
| holstein | den: can you route *anything* through jack? | 14:52 |
| holstein | den: you get software working? output? like a file that plays? correct? | 14:52 |
| den | I don't know for certain. | 14:53 |
| den | How can I test that? | 14:53 |
| holstein | den: route something through jack, like a known good audio file in audacious | 14:53 |
| holstein | if you dont get output from there, you wont pass the input through anything and get output | 14:53 |
| den | I don't have audacious installed, let me get it really quickly. | 14:54 |
| holstein | den: whatever you use that uses jack.. vlc, whatever | 14:55 |
| holstein | yoshimi | 14:55 |
| holstein | just make sure that jack is running, then that it is outputting to the card | 14:55 |
| holstein | then, you can read that, even in 13.10, that input is inappropriate for instruments | 14:55 |
| den | Okay it won't play the loaded file. It doesn't progress at all. | 14:55 |
| holstein | den: wont play? or wont route? | 14:56 |
| holstein | den: what would i do? try and thin *all* of this out... stop jack. then, get *any* audio file playing | 14:56 |
| holstein | then, you'll call that the "known good audio file".. you'll take the known good audio file and get it playing with jack | 14:56 |
| holstein | *then* move on to line inputs, such as the guitar | 14:56 |
| den | Okay so the audio file does not work while Jack is open at all, and even when it's closed it seems to cause vlc to hang completely. | 14:59 |
| holstein | den: so, thats not a "known good" audio file, then | 14:59 |
| holstein | den: now, you have additional quesitons to ask and answer.. is the file supported by a codec? is it corrupt.. etc | 14:59 |
| den | I mean, any of the audio files on my computer don't work after I open Jack, close it, close VLC, and re-open VLC. | 14:59 |
| holstein | den: you cant "close" jack.. it must be stopped.. if its runing in teh background, it takes over the audio device, and then, you have qjackctl closed and cant route | 15:00 |
| holstein | !proaudio | 15:00 |
| ubottu | For information on professional audio tools in Ubuntu, see https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro | 15:00 |
| den | Oh I did stop it before I quit qjackctl. | 15:01 |
| holstein | den: vlc, also must be set to use jack, or pulse | 15:01 |
| holstein | but, you need not get to fixated on getting that to work.. this is not a fix for you.. its just troubleshooting.. get *anything* to make *any* sound in jack.. yoshimi is a nice one | 15:01 |
| den | Okay so I installed Yoshimi, started Jack and opened it. Now what do you want me to do? | 15:03 |
| holstein | den: i want you to literally make a sound with jack running | 15:03 |
| holstein | den: whatever you think is the shortest and most reliable path to you being ablt to create a noise in jack | 15:04 |
| den | But I don't know how to do that. I am a complete Linux newbie. | 15:04 |
| holstein | !proaudio | 15:04 |
| den | What is that? | 15:05 |
| holstein | den: yoshimi makes its own sounds, and has a built in keyboard, so, routing the audio is all that is required to see that audio attempt to hear audio | 15:05 |
| den | Okay I can see where there is audio, but i can't hear it. | 15:06 |
| holstein | den: then, thats a problem. and nothing you plug in, such as your guitar, or rakarrak, or anything else will make sound til you learn to route there, and what the issue is | 15:06 |
| den | Well how do I learn that? | 15:07 |
| holstein | den: there is no need to troubleshoot "guitar through rakarrak" yet, when, actually, *no* audio is going through jack | 15:07 |
| den | Okay so I just connected left and right to playback 1 and 2 and now I get sound. | 15:07 |
| holstein | den: you have to/need to make *all* connections like that | 15:08 |
| holstein | den: you'll see the input on the device on the left in the "connect" panel of qjackctl.. you'll route the guitar plugged into that jack from there.. | 15:08 |
| holstein | den: you wont see a label named "guitar input".. it can be labeled literally anything.. so, i'll just test them til i see what is what | 15:09 |
| holstein | you have no guarantee from the creators of the device for alsa/linux support, so the labels cannot be trusted | 15:09 |
| holstein | den: i must be off.. i'll leave you with coelebs .. and also, the #opensourcemusicians channel can be helpful.. but i think you'll find you have a simple routing issue there | 15:10 |
| den | Thanks Holstein. | 15:11 |
