Can't get it to work (no sound and media)

Hi everyone,

I have an iRig USB keyboard, a USB DAC, and a USB stick with the basic Mellotron and Piano samples connected to the Raspberry Pi 2B. However, I can get no sound. I tried chaning the AUDIO_DEVICE_ID line in samplerbox.py but it doesn't change anything, and I also don't have any files in the /media/ folder even though my usb is plugged in. I tried to manually copy the Mellotron folder to the /media/ folder to see if it would work, but still no sound.

I looked through all the forum posts, and even though some people had a similar issue I didn't find a solution.

Any help would be greatly appreciated!

Hello, try with a recent USB stick, i had problems with an old one. And after if its doesnt work, you need to connect a console to the Pi: Hdmi screen and keybord or connection via putty on your computer to observe what happend... good luck

I've tried another USB stick but it makes no difference. I'll try a third one. I'm already connected via SSH/Putty, and the program itself is running (checking with the command that shows up on startup). I don't know what specific codes to look up to check for any errors.
Thanks for the reply

Have you tried with the samples put directly on the SD card (in root) ? Does it work ?

I put a folder with samples named "0 Mellotron MkII Flute" in the /root/ directory, and set SAMPLES_DIR = "/root/" , but I still get nothing.

Same if I put it in /root/SamplerBox/ and SAMPLES_DIR = "/root/Samplerbox". Also tried another midi keyboard but no change. Is there a way to check if my DAC is being used correctly? The problem might lie there

It's a long shot but maybe try with two folders, one "0 saw" and the other "1 Mellotron" (for example). Sometimes it works (cf http://samplerbox.org/forum/50).
Also, what happens when you input ls /media (if the samples are there) ? (cf :http://samplerbox.org/forum/24).
Finally, have you tried your config using the portable samplebox (http://samplerbox.org/forum/9) ? This might help pinpoint the problem.

Thanks for your help, I ran the "systemcl status samplerbox" line again to check for problems and this time I had a failure. Turns out that it was a naming mistake in the samplerbox.py file: I had put true instead of True with a capital. At the moment it works when running the samples straight from the /SamplerBox folder, which is great news.

However, I still get nothing from my USB stick. I ran the ls/media code but I got no results from 2 different usb sticks. Since I'm working on an enclosed build it would be quite handy to be able to use a usb. Any suggestions? I noticed there were more people with the problem but didn't find a definitive solution.

Much thanks for the help already, I appreciate it.

UPDATE: just checked via SSH and I do see my sample folders now in /media, and it seems to work now with SAMPLES_DIR = "/media" ! It does work with only 1 of my usb sticks, is there any known reason for this? I would've preffered using my other one, but if there is no solution then I'll have to live with it.

As you've probably seen, there are reports on the forum of some sticks working better than others, unfortunately, like the DACs. I don't know that there any way to make a stick more compatible.
