Ubuntu studio 18.04 - Jack Setup w/ Multi FX pedal

Post by debosaur »

Hello Everyone

I'm sure this has been one of the most common subjects for newbies, but I'm sure I must be doing something wrong, and I'd love get it figured out.

I'm using Ubuntu Studio 18.04 on a laptop. Have a boss GT series guitar multi fx/ modeling pedal and a scarlet 2i2.

All I really want to do is be able to record the guitar using my own effects to the DAW, and be able to play the guitar through headphones, along with an mp3.

After connecting everything up, I can see the scarlet is responding because I can turn the gain up and see the light come on when it clips out. My issue is, I can't hear anything in my phones no matter what I try.

I 'think' I set Jack up correctly. The input was set to the audio interface, and I tried the output thru the laptop speakers, headphone jack, and tried to monitor thru the scarlet in jack setup, all to no avail.

Like I said- I'm sure it's a user error thing, but I'm a bit stuck at the moment and was hoping someone would be kind enough to throw a couple of suggestions my way?

Thank you

Welcome.

Which DAW do you use for recording?
Qjackctl uses your audio/MIDI interface? - http://libremusicproduction.com/article ... -jack.html - https://github.com/jackaudio/jackaudio. ... ack1_jack2 - https://linux.die.net/man/1/jackd
(Does the DAW used use jackd?
In alsamixer everything is set up correctly? - https://linux.die.net/man/1/alsamixer - https://linux.die.net/man/1/alsactl)

Can you take a screenshot of qjackct connections and post it here?

Hey thanks for the reply and the info. I went ahead and upgraded to a fresh 19.10 - I'll look thru those links you posted and will post a screenshot when I get a few minutes.

I'd ideally be using Ardour but I can use Audacity for what I'm trying to accomplish.

Right now I'm more interested in being able to play along to some mp3s or something and have it all go thru my headphones --- though I'm sure if I could get that part working then the DAW would probably pick the guitar signal up as well.

Anyway I'll look at the stuff you posted and will reply back. Thank you

@Ardour 7. Recording options (In / Disk)
Recording options
The most noticeable button here is the Record Enable one, with a red circle. When enabled, next time the Global record will be armed and playback started, everything that comes from the input of the track will be recorded. Right clicking a disabled record button allows to enable Rec-Safe, thus protecting the track against accidental recording.

The buttons on the right, In and Disk, show what the user is listening to by lighting up, between the Input and the actual content of the playlist on Disk.

They also allow to override the automatic switching by pressing them to lock one source or the other to be what the user is hearing.
