Olá!
Sou novo no universo linux.
Rakarrack é um processador de efeitos de guitarra
Estava querendo utiliza-lo porem estou com um erro quando quero abrir ele
Segue abaixo o que aparece no meu terminal quando tento abrir ele pelo terminal.

You don't appear to have a sane system configuration. It is very likely that you
encounter xruns. Please apply all the above mentioned changes and start jack again!
Cannot make a jack client, is jackd running?
