Ho un problema con "Jack".<br />
<BR>Se lo faccio partire da utente root con il comando <strong>jackd -R -d alsa </strong>mi parte correttamente. Se invece tento di dare lo stesso comando da user mi da questo output : <br />
<BR><em><br />

<BR>E poi esce!<br />
<BR>Uso il kernel 2.6.11 con il preeemptible attivato.<br />
<BR>Se lancio jack senza il realtime parte correttamente anche da "user". Penso quindi sia un problema di permessi, ma non so dove!<br />
<BR><br />
<BR>Qualche dritta?<br />

<BR>Grazie,<br />

Niente da fare...<br>
