Well, I'm always trying to get midi audio recording working, or at least just one of these :) ; well, I'm trying very hard but .... nothing's working ; I'm trying since a long time but ..... I have a P4 computer and mandrake 9.2 with a low latency kernel ( 2.4.22-21mm.2mdk). Well alsa is running and when I launch alsaconf, it says that my sound card is "intel 8x0 Silicon Integrated Systems [SiS] Sound Controller" (in fact, sound is integrated in the motherboard (an Asus P4S8X-X), and the motherboard doc says that the chip is an ADI AD 1980 6-channel audio codec) ; in an another place, I've also seen SiS 7012...... Alsaconf don't perform the last thing, playing a song 'cause something is missing : Loading driver... /usr/sbin/alsaconf: line 568: rcalsasound: command not found Setting default volumes... =============================================================================== Now ALSA is ready to use. For adjustment of volumes, please use alsamixer or gamix. Have a lot of fun! So I'm trying to launch jack and, as root, I type #jackd -d alsa -r 44100 and here is what I get : jackd 0.95.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. apparent rate = 44100 creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|rt|32bit control device hw:0 configuring for 44100Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead And I'm obliged to do a Ctrl C to stop the process and Iget the mess : jack main caught signal 2 When switching verbose option for starting jack, jackd -vd alsa -r 44100, I get also thiese lines : new buffer size 1024 registered port alsa_pcm:capture_1, offset = 4096 registered port alsa_pcm:capture_2, offset = 8192 registered port alsa_pcm:playback_1, offset = 0 registered port alsa_pcm:playback_2, offset = 0 registered port alsa_pcm:playback_3, offset = 0 registered port alsa_pcm:playback_4, offset = 0 registered port alsa_pcm:playback_5, offset = 0 registered port alsa_pcm:playback_6, offset = 0 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() 5874 waiting for signals load = 0.0301 max usecs: 14.000, spare = 23205.000 load = 0.0474 max usecs: 15.000, spare = 23204.000 **** alsa_pcm: xrun of at least 0.912 msecs load = 0.0517 max usecs: 13.000, spare = 23206.000 **** alsa_pcm: xrun of at least 5.614 msecs load = 0.1184 max usecs: 43.000, spare = 23176.000 load = 0.0851 max usecs: 12.000, spare = 23207.000 load = 0.0705 max usecs: 13.000, spare = 23206.000 load = 0.0633 max usecs: 13.000, spare = 23206.000 load = 0.0812 max usecs: 23.000, spare = 23196.000 load = 0.0686 max usecs: 13.000, spare = 23206.000 load = 0.0666 max usecs: 15.000, spare = 23204.000 load = 0.0591 max usecs: 12.000, spare = 23207.000 load = 0.0554 max usecs: 12.000, spare = 23207.000 load = 0.0514 max usecs: 11.000, spare = 23208.000 load = 0.0515 max usecs: 12.000, spare = 23207.000 load = 0.0538 max usecs: 13.000, spare = 23206.000 load = 0.0635 max usecs: 17.000, spare = 23202.000 load = 0.0576 max usecs: 12.000, spare = 23207.000 load = 0.0783 max usecs: 23.000, spare = 23196.000 load = 0.0758 max usecs: 17.000, spare = 23202.000 load = 0.0766 max usecs: 18.000, spare = 23201.000 load = 0.0728 max usecs: 16.000, spare = 23203.000 **** alsa_pcm: xrun of at least 27.009 msecs load = 0.1419 max usecs: 49.000, spare = 23170.000 load = 0.1205 max usecs: 23.000, spare = 23196.000 load = 0.1012 max usecs: 19.000, spare = 23200.000 load = 0.1001 max usecs: 23.000, spare = 23196.000 load = 0.0845 max usecs: 16.000, spare = 23203.000 load = 0.0767 max usecs: 16.000, spare = 23203.000 load = 0.0642 max usecs: 12.000, spare = 23207.000 load = 0.0773 max usecs: 21.000, spare = 23198.000 load = 0.0882 max usecs: 23.000, spare = 23196.000 load = 0.0807 max usecs: 17.000, spare = 23202.000 load = 0.0727 max usecs: 15.000, spare = 23204.000 load = 0.0729 max usecs: 17.000, spare = 23202.000 load = 0.0752 max usecs: 18.000, spare = 23201.000 load = 0.0850 max usecs: 22.000, spare = 23197.000 **** alsa_pcm: xrun of at least 9.031 msecs load = 0.1308 max usecs: 41.000, spare = 23178.000 load = 0.0998 max usecs: 16.000, spare = 23203.000 load = 0.0758 max usecs: 12.000, spare = 23207.000 load = 0.0745 max usecs: 17.000, spare = 23202.000 jack main caught signal 2 stopping driver detaching driver unloading driver So, nothing is working neither muse, nor rosegarden or ardour or .....anything else Last thing when I perform lsmod, iget this : Module Size Used by Not tainted ide-cd 34148 0 (autoclean) lp 8288 0 parport_pc 25768 1 parport 35560 1 [lp parport_pc] snd-seq-oss 32800 0 (unused) snd-seq-midi-event 6336 0 [snd-seq-oss] snd-seq 45104 2 [snd-seq-oss snd-seq-midi-event] snd-pcm-oss 43780 0 snd-mixer-oss 14224 0 [snd-pcm-oss] snd-intel8x0 23112 0 snd-pcm 81700 0 [snd-pcm-oss snd-intel8x0] snd-timer 20068 0 [snd-seq snd-pcm] snd-ac97-codec 47064 0 [snd-intel8x0] gameport 3284 0 [snd-intel8x0] snd-page-alloc 9044 0 [snd-intel8x0 snd-pcm] snd-mpu401-uart 5024 0 [snd-intel8x0] snd-rawmidi 18688 0 [snd-mpu401-uart] snd-seq-device 5832 0 [snd-seq-oss snd-seq snd-rawmidi] snd 45668 0 [snd-seq-oss snd-seq-midi-event snd-seq snd-pcm-oss snd-mixer-oss snd-intel8x0 snd-pcm snd-timer snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device] soundcore 6564 0 [snd] Well if someone have any idea, it would be nice to get this working ; I really need to make music with linux, I don't want to be obliged to run my atari falcon with cubase audio until the end of time !!! But, really, I don't know what to do.... cordialement,
