Dotaz: Jack server nejde spustit

[jake]

Vím, že už podobné problémy byly v tomto fóru řešeny, ale bohužel jsem svůj problém nevyřešil. Stáhnul jsem si Ardour a Jamin a když je chci spustit Ardour mi píše, že

Jack server is not running nebo, že Jack is running as another user

. Jamin píše

can not contact jack server

. Zkoušel jsem spustit Jack příkazem

jackd -R -d alsa

podobné jsem zkoušel jako root, ale zaseklo se to uprostřed výpisu a dál se nic nedělo. Mám nainstalováno Ubuntu Hoary a jack mám nainstalováno. Předem díky za pomoc.

1. Stahl jsem utilitu Qjackctl

2. Nastavoval jsem hodnoy tak dlouho, az me to jelo ) a nelupkalo (resp. me zvukovka jela jen v rezimu prehravani a ne nahravani)

Ja to spoustim i s identifikaci zvukovky (mam v systemu 2, na jedny mi nejde MIDI). Nesmis ten jack spoustet jako ROOT, ale jako normalni user, jinak to muze delat tyhle veci. Muj prikaz na inicializaci jacku:

jackstart -d alsa -r 44100 --device hw:1

Ten qjackctrl je super utilitka, doporucuji.

Díky, ale bohužel to stále nejde. Stáhnul jsem si qjackctrl, ale stejně mi to nejde stále spustit. Nevím, co nastavit. Výpis je:

Zajimava hlaska: ALSA: Cannot open PCM device alsa_pcm for playback. Falling back to capture-only mode cannot load driver module alsa Jakoby neco blokovalo audio vystup.
