Hi all, I installed a new card : maudio delta 1010LT. OS is Ubuntu linux 5.04 ... kernel-image-2.6.12-2-multimedia-386 ... kernel-patch-2.6-realtime-lsm ... modules snd_seq_midi snd_seq_midi_event snd_seq snd_rawmidi ... snd_timer snd soundcore realtime I started jackd with qjackctl. The process is running : ... >> ps aux |grep jackd ... root 7867 0.6 5.5 28476 28868 ? SLsl 20:25 0:00 /usr/bin/jackd -R -dalsa -r44100 -p512 -n2 -D -Chw:1 -Phw:1 but qsynth doesn't want to connect to it. May be alsa is not correctly configured ? May be qjackctl is not correctly configured ? I don't know which walue I have to put in : - interface : hw:1 (Maudio Delta 1010LT) or hw1,0 (ICE1712 multi) - input device : hw:1 (Maudio Delta 1010LT) or hw1,0 (ICE1712 multi) - output device : hw:1 (Maudio Delta 1010LT) or hw1,0 (ICE1712 multi) Thanks for your help if you have an idea !!! Here are the steps that I did : - $alsamixer -c 1 to set inputs/outputs value - $qjackctl (root) which seems to be ok for my part ... >> QJACKCTL STARTUP : ... 20:24:44.599 Patchbay deactivated. ... 20:24:44.872 Statistics reset. ... 20:24:44.942 MIDI connection graph change. ... 20:24:45.080 MIDI connection change. ... 20:25:02.610 Startup script... ... 20:25:02.610 artsshell -q terminate ... 20:25:02.956 Startup script terminated with exit status=256. ... 20:25:02.956 JACK is starting... ... 20:25:02.956 /usr/bin/jackd -R -dalsa -r44100 -p512 -n2 -D -Chw:1 -Phw:1 ... 20:25:02.960 JACK was started with PID=7867 (0x1ebb). ... cannot write to jackstart sync pipe 4 (Bad file descriptor) ... jackd: wait for startup process exit failed ... jackd 0.99.0 ...
