jack xruns mit Delta 1010LT

[khz]

Hallo,
habe - mal wieder - prob mit jack. Bekomme xruns wenn ich jack starte ohne das irgendein jack-programm laeuft.
Jack lief schonmal gut mit "Latency 5.33 msec". Nach evt. "apt-get install *audio-tools*" haben die xruns eingesetzt, reine Vermutung.
Habe Sidux nach der Wiki eingerichtet.

hallo,

kann dir leider nicht weiterhelfen, aber schau mal hier:

cannot use real-time scheduling (FIFO at priority 99) [for thread -1228403824, from thread -1228403824] (1: Operation not permitted)

sieht irgendwie nach problemen mit dem realtime-kernel aus. hab keine ahnung was, aber ich würde mir nochmal den anfang von dieser sidux-seite anschauen, ob da alles stimmt (richtiger kernel installiert und gebootet und allles richtig eingetragen und so)...

viel erfolg

grüsse l.chaos

[khz]

#hmm, wie http://www.audio4linux.de/forum/viewtopic.php?t=749
#da.

[khz]

hast Du den Kernel erneuert? Bei mir läuft's mit 2.6.22...-rt und 2.6.23...-rt sehr viel besser als mit diversen 2.6.24...-rt (alle Kernel sowohl -makke und auch Eigenübersetzung).
Reproduzierbares Verhalten auf 'nem frisch installierten sidux xmas-07 mit aktuellem -makke als auch auf nem aktuellen kanotix (mit selbstgebauten 2.6.24-rt Kernel); auf beiden Systemen (gleiche HW) treten xruns von selber auf, wie von Dir beschrieben.

evt. Kernel Version prob. Teste ich mal.

[khz]

Hy,
die limits.conf

Code: Alles auswählen

@audio - rtprio 90
@audio - nice -5
@audio - memlock unlimited
#@audio - memlock 750000

sieht ok aus finde ich.

Was ich merkwürdig finde:
-P89

Code: Alles auswählen

:~$ cat .jackdrc
/usr/bin/jackd -R -P89 -p128 -t2000 -u -dalsa -r48000 -p128 -n2 -D -Chw:1 -Phw:1 -s -m -H -M -I1 -O2

Code: Alles auswählen

cannot use real-time scheduling (FIFO at priority 99) [for thread -1228854384, from thread -1228854384] (1: Operation not permitted)

Jack läuft mit xruns.

Wenn ich z.b.
-P79

Code: Alles auswählen

 /usr/bin/jackd -R -P79 -p128 -t2000 -u -dalsa -r48000 -p128 -n2 -D -Chw:1 -Phw:1 -s -m -H -M -I1 -O2

erscheint die Fehlermeldung (siehe oben (FIFO at priority 99)) NICHT.
Jack läuft mit xruns.

Wenn ich OHNE Realtime jack starte läuft er problemlos

Code: Alles auswählen

/usr/bin/jackd -p128 -t2000 -u -dalsa -r48000 -p128 -n2 -D -Chw:1 -Phw:1 -s -m -H -M -I1 -O2

und kann mehrere jack-programme öffnen OHNE xruns.

Habe zum Test mal einen 2.6.23.1-rt5-makke-s22_1_i386 Kernel install (thx horo).

Mit 2.6.23.1-rt5-makke-s22_1_i386:
-P89

Code: Alles auswählen

/usr/bin/jackd -R -P89 -p128 -t2000 -u -dalsa -r48000 -p128 -n2 -D -Chw:1 -Phw:1 -s -m -H -M -I1 -O2 

Code: Alles auswählen

cannot use real-time scheduling (FIFO at priority 99) [for thread -1228440688, from thread -1228440688] (1: Operation not permitted)

# -P89 |--| (FIFO at priority 99) <-- ?

Mit -P79: Keine Fehlermeldung aber xruns (sehr wenige bzw über längere Zeit).
Ohne -R gar keine xruns.

Mit 2.6.24-2.6.24.4.makke-rt4.2-sidux-686: -P89 wie beim 2.6.23.1 Kernel,
bei -P79 auch wie beim 2.6.23.1 Kernel doch es treten mehr/schneller xruns auf.
Ohne -R gar keine xruns.

Von horo eine Antwort:
Das liegt wohl daren, dass qjackctl einen jackd (als Watchdog ?) mit Priorität+10 starten will (89+10->99), aber nur Prioritäten bis 90 möglich sind. P81 gibt 'nen Fehler (FIFO at priority 91), P80 läuft ohne Fehler. Das ändert aber nix an den xruns mit 2.6.24...
Sowohl der interne CS46xx als auch ein externer usb-audio (Burr-Brown (Texas Inst. Japan) PCM2902 Chip) zeigen xruns, auch wenn keine clients laufen, bei 2.6.22 bzw 2.6.23 ist (fast) Ruhe. Auch probeweises Stillegen von ACPI, das bis ca. 2.6.16.xx diverse Probleme bereitete (kein sauberer shutdown, Hänger,...), ändert nichts. Die Interrupts habe ich im Bios soweit wie möglich aufgedröselt:
cat /proc/interrupts
rtirq.sh status

Jo,

war der Dienst powersaved/kpowersave dran beteiligt.
Nun rennt jack soweit --fein.

Wegen mehrere Soundkarten:
wird nicht in

Code: Alles auswählen

/etc/modules

eingetragen sondern in

Code: Alles auswählen

:~$ cat /etc/modprobe.d/sound
alias snd-card-0 snd-via82xx
options snd-via82xx index=0

alias snd-card-0 snd-ice1712
options snd-ice1712 index=1

So funkt bei mir.
Mehrmals für die verschiedenen Soundkarten "alsaconf" verwenden und den code sichern, danach zusammenfügen.
"snd-card-0 / snd-card-0"
oder
"snd-card-0 / snd-card-1"
???
