Non sono pratico di linux ma sto cercando di sostituire il mio sequencer di windows (e tutto il sw ke usavo per hd recording, e piu` in generale tutto windows) con del fantastico software open source...ma ho nuovamente bisogno del vostro aiuto:
ho seguito alla lettera l`how to di questo forum ma al comando per testare il funzionamento
Code:

jackstart -v -R -d alsa -H -M -m

mi da il seguente errore
Code:

jackstart: cannot get realtime capabilities, current capabilities are:
           =ep cap_setpcap-ep
    probably running under a kernel with capabilities disabled,
    a suitable kernel would have printed something like "=eip"


non so se centra ma io ho cercato la voce capibilities nel .config ma ho trovato solo
Code:

CONFIG_SECURITY_CAPABILITIES=m

impostato come indicato nell`how to

non so se puo` essere utile ma questo e il mio lsmod
Code:

Module                  Size  Used by
pcmcia                 24532  4
yenta_socket           20104  2
rsrc_nonstatic         11072  1 yenta_socket
pcmcia_core            44872  3 pcmcia,yenta_socket,rsrc_nonstatic

snd_ac97_codec         85392  1 snd_via82xx
snd_pcm                89160  2 snd_via82xx,snd_ac97_codec
snd_page_alloc          9480  2 snd_via82xx,snd_pcm
snd_mpu401_uart         7360  1 snd_via82xx
snd_rawmidi            21824  1 snd_mpu401_uart
realtime               10056  0
nvidia               4053436  14

se potete aiutarmi ve ne sarei grato...

Non ne sono sicuro e non vorrei dire eresie, ma prova ad eseguirlo da root (oppure a dargli il +S), perchè nel mio caso con arts ha funzionato...

io ho trovato questa guida, il comando che citi non c'è, invece ne usano un'altro.

magari è una versione vecchia, però... tentar non nuoce.

bene ma dato che *non* lo avevi riportato *non*
potevo sapere che fossi già a conoscenza di quel 3d

Da root ti dà gli stessi errori, giusto? Hai controllato i permessi dei device audio?

ho provato sia quella di questo forum che quella ufficiale...e comunque tranne il test finale fanno entrambe la stessa cosa....e non va comunque.
non so se puo` essere utile saperlo ma l`audio mi funziona e ho un amd 64 bit...

RIEDIT:
scusate per il doppio post...ho sbagliato.


ho installato il tool grafico di jackq "jackctl" e mi da questo errore
Code:
01:21:33.129 Could not open ALSA sequencer as a client. MIDI patchbay will be not available.
ALSA lib seq_hw.c:446:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory

Per controllare i permessi usa
Code:
ls -la /dev/snd
e posta l'output. Poi come misura estrema puoi sempre riprovare da capo (ricontrollando ogni passaggio). Cmq un consiglio. Se hai messo i driver alsa integrati nel kernel, toglili e usa quelli esterni, a me quelli interni delle volta hanno causato problemi.

ps. che scheda audio hai?

lscpi relativo alla scheda audio:
Code:
Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller


poi

Code:
 ls -la /dev/snd


Code:

crw-rw----   1 root audio 116, 33 Jul 17 13:20 timer


i driver alsa gli ho messi come moduli...ho rifatto la procedura ma non funziona mi da gli stessi errori che ho postato prima....
Code:

jackstart: cannot get realtime capabilities, current capabilities are:
           =ep cap_setpcap-ep
    probably running under a kernel with capabilities disabled,
    a suitable kernel would have printed something like "=eip"



mmm forse ho trovato l`errore
Code:

 <M>   Default Linux Capabilities

come carico questo modulo? come faccio a sapere che nome gli assegna per caricarlo?

EDIT:Correggo la mia ultima affermazione
Code:
<M>   Default Linux Capabilities


questo deve rimanere tale....ma ancora non mi funziona....:(

Segui questa: http://wiki.gentoo-italia.net/index.php/Audio_e_HD_Recording_con_Gentoo

Considera che gli utenti non hanno permessi di lanciare processi realtime (nemmeno se passi a jack -m). Ti serve un kernel patchato e ti serve realtime-lsm.

Consiglio caldamente di installare anche qjackctl tenendo aperta la finestra delle connessioni.
