Hey sky ! Glad to see you back on trackers l'ami !

In my experience the PI's built-in audio is pretty crap. Not sure how the various handheld PI things do though. A certain lo-finess can of course be a desired thing, but if not, I'd recommend something like the Pisound board https://blokas.io/.
This discussion makes me thing that one could build oneself a nice tracker station with one of these https://www.raspberrypi.org/products/ra … h-display/ and a laser-cut enclosure.
But it's probably a silly idea

Hey kool skull fuck the fuck off. You are not welcome here.

Rasberry pi handheld is best. Bleo is right

If you those libs are 404 you need to add the sources because fuck Linux that’s why.

Also make sure you are using the 32bit version of whether os  you installed

no i'm using the lgpt.rpi-exe

I've already installed those libraries though... it only worked when i removed the :i386 otherwise it wasn't retrievable.

fwiw, there does seem to be an issue with fullscreen using jesse or newer raspbian builds. i've been trying to sort it out in the facebook group (had to finally upgrade to something newer than wheezy since i got a piTFT+ & i couldn't get that to work in wheezy). i'll probably end up going with command line/autoboot eventually myself, but it's definitely an issue for some reason (as confirmed by another user who also had trouble in raspbian stretch)

OK, two ideas:

1) Which build of piggy are you using? From that log, it looks like debian? There's a specific pi build here at the bottom with the ghettos (ALWAYS use the ghettos): http://littlegptracker.com/download.php
2) That being said, once you use the ghettos, different sound libs need to be installed.

sudo apt-get install libasound2-plugins:i386

And maybe you'll have to remove the ":i386" again, maybe not! This is what got it working for me on debian but I've never tried on a pi...

i think i need to figure out how i can change lgpt to play using either the usb audio interface or using pulse .....

I'm not sure how i can do that.. i dont really know all the of the config options.

EDIT:

Here is the lgpt log file:

I installed MilkyTracker on the pi to test the audio quality while playback and it's much cleaner! it seems like only lgpt has issues....

When i ran milkytracker from the cli it said

SDL: using audio driver: pulse

Meanwhile when i run lgpt it says:
RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,1), Device or resource busy

but it still plays audio but has the shitty sound.

yeah! good call on the CLI instead of the DE, worked like a charm.
I made a script to run lgpt on startup and now it works great...

However... the audio properties are still the same...

crackling frequently sometimes even slight hiccups in the timing of the sequence...

as for the audio soundcard i'm using a Presonus audiobox USB (only thing i have) it's supposed to be bus powered though...

i can't seem to get any audio out of it however... it still is stuck on the analog output.

Are you running piggy from the command line or from the desktop? Did you run apt-get update?

Cant compare two different apps, linux succckkks

Id suggest

-Disable booting to the Desktop but rather to the command prompt
- making sure everything is updated
- instal alsa tools if you havent
- boot the pi with the usb soundcard installed, dont add it
- and show us the config

Will do that once I get home but the thing is, when I’m watching YouTube or something the sound is excellent. It’s only when I’m on LGPT that it crackles and pops even though the CPU LOAD shown on top in raspbian is very very low

Can you post your config.xml? maybe you have bad syntax in there.

What usb sound card? Some cheap ones are SOFTWARE ONES that force the udnerpwoered pi to do some rendering, the crackling is related to cpu load.
