Package: ardour-gtk Version: 0.9beta28-1 Severity: important Hi,
I'm not sure whether this is a real bug, or whether it should be filed against ardour or jack. I'm trying to archive some cassette recordings to digital storage media using ardour. I have a successful jack installation, have a real-time-enabled 2.6.12-rc2-mm3 kernel, and > 24hrs worth of disk space available to ardour for recording. When I try to dub a single 45-minute-long cassette side at cd quality (44.1 KHz rate), ardour always gets disconnected from jack at the same point, about 40 minutes into the recording. I cannot record for a longer period than about 40 minutes. This behavior is completely reproducible, unfortunately. Jack isn't reporting *any* xruns prior to disconnect. Roughly doubling the sample rate to 96 KHz roughly halves the time to ardour disconnect -- it seems to scale as though it's hitting a hard buffer limit or something.. At disconnect the jack verbose message stream looks like: ============================================================ load = 2.3013 max usecs: 537.000, spare = 22682.000 load = 2.2984 max usecs: 533.000, spare = 22686.000 load = 2.2991 max usecs: 534.000, spare = 22685.000 load = 2.3016 max usecs: 535.000, spare = 22684.000 load = 2.3050 max usecs: 536.000, spare = 22683.000 load = 2.3111 max usecs: 538.000, spare = 22681.000 load = 2.3356 max usecs: 548.000, spare = 22671.000 load = 2.3070 max usecs: 529.000, spare = 22690.000 load = 2.2668 max usecs: 517.000, spare = 22702.000 subgraph starting at ardour timed out (subgraph_wait_fd=15, status = 0, state = Triggered) at 2973749462 waiting on 15 for 24497 usecs, status = 1 sig = 2973724958 awa = 0 fin = 0 dur=0 subgraph starting at ardour timed out (subgraph_wait_fd=15, status = 0, state = Triggered) at 2973774458 waiting on 15 for 24920 usecs, status = 1 sig = 2973749534 awa = 0 fin = 0 dur=0 subgraph starting at ardour timed out (subgraph_wait_fd=15, status = 0, state = Triggered) at 2973799464 waiting on 15 for 24930 usecs, status = 1 sig = 2973774529 awa = 0 fin = 0 dur=0 subgraph starting at ardour timed out (subgraph_wait_fd=15, status = 0, state = Triggered) at 2973824466 waiting on 15 for 24926 usecs, status = 1 sig = 2973799536 awa = 0 fin = 0 dur=0 subgraph starting at ardour timed out (subgraph_wait_fd=15, status = 0, state = Triggered) at 2973849462 waiting on 15 for 24920 usecs, status = 1 sig = 2973824538 awa = 0 fin = 0 dur=0 client ardour has died/exited client failure: client ardour state = Triggered errors = 1 removing client "ardour" from the processing chain DIS-connect ardour:Audio 1/out 2 and alsa_pcm:playback_2 DIS-connect ardour:Audio 1/out 1 and alsa_pcm:playback_1 DIS-connect alsa_pcm:capture_2 and ardour:Audio 1/in 2 DIS-connect alsa_pcm:capture_1 and ardour:Audio 1/in 1 DIS-connect ardour:click/out 1 and alsa_pcm:playback_1 DIS-connect ardour:master/out 2 and alsa_pcm:playback_2 DIS-connect ardour:master/out 1 and alsa_pcm:playback_1 DIS-connect ardour:auditioner/out 2 and alsa_pcm:playback_2 DIS-connect ardour:auditioner/out 1 and alsa_pcm:playback_1 timebase master exit ++ jack_rechain_graph(): client qjackctl-7078: start_fd=6, execution_order=0. client qjackctl-7078: wait_fd=12, execution_order=1. client alsa_pcm: internal client, execution_order=2. -- jack_rechain_graph() 12:40:54.719 Audio connection graph change. removing failed client ardour state = Not triggered errors = 0 removing client "ardour" ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client qjackctl-7078: start_fd=6, execution_order=0. client qjackctl-7078: wait_fd=12, execution_order=1 (last client). -- jack_rechain_graph() load = 1.2131 max usecs: 37.000, spare = 23182.000 load = 0.6884 max usecs: 38.000, spare = 23181.000 load = 0.4131 max usecs: 32.000, spare = 23187.000 load = 0.2905 max usecs: 39.000, spare = 23180.000 load = 0.2013 max usecs: 26.000, spare = 23193.000 load = 0.1825 max usecs: 38.000, spare = 23181.000 load = 0.1278 max usecs: 17.000, spare = 23202.000 load = 0.1479 max usecs: 39.000, spare = 231 ============================================================= This behavior is: -- reproducible with several different sound cards/interfaces [I've tried an Audigy 2, nForce2 and usb-based mAudio Transit with the same result]. -- reproducible across several kernels [2.6.12-rc2-mm3, 2.6.11-ac6, patched Debian 2.6.11, vanilla 2.6.11]. The host box is a Shuttle SN-41G2, an nForce2-based XPC. It has a gigabyte of memory and tons of free disk space for ardour to use. I haven't tried to reproduce this problem on another machine but can do so with a little work. And I'm a complete ardour/jack neophyte and am not certain whether ardour is failing repeatedly or there is some issue with jack or alsa or even a config issue somewhere. I haven't seen other references or bugs reporting this behavior so I'm more than a little suspicious of my setup. Recording works perfectly up to the point of failure. Happy to do further testing and supply more info. Apologies if this isn't even interesting...
