MODEP with Berryboot

#1

Just found the MODEP project today via https://berryboot.alexgoldcheidt.com/ Berryserver.

I have installed and launched the image so can login via ssh just fine. However if i boot with or without ethernet can’t reach the web interface on the default http://172.24.1.1 or local network address. so expect I rushed a step or just missed the point somewhere, has anyone else here had a go?

Yes set up hw:0 and got this when running through the troubleshooting docs.
modep@modep:~ $ sudo systemctl status mod-host
● mod-host.service - MOD-HOST

perhaps a reboot? OK that did it!

any advice or suggestions welcome cheers

Looks like the services are failing to start, most likely you have to find the right parameters for the Jack backend.

Which audio card do you intend to use? If you’d like to use the built in BCM audio jack, you must also increase the buffer sizes which adds to latency, as well as use 44100Hz sampling rate, try using something like this in jack.service:

ExecStart=/usr/bin/jackd -v -t 2000 -P 75 -d alsa -d hw:0 -r 44100 -p 256 -n 3 -X seq -s -S

See https://blokas.io/modep/docs/Sound-Card-Setup/ for steps on how to edit the file.

thanks for the extra detail… got the webinterface rolling… not sure about which sound card as yet… will try a few we have here.

cheers
