audacity-1.3.4-alt0.9.2 When I start audacity: $ audacity exec of JACK server failed: No such file or directory and then it waits around 6 seconds for something (no disk or CPU activity), only after that the GUI appears. On some older versions there was no such behavior. It's negligible for one time, but if I start it often (and if I'm in a hurry to start a recording then), then this delay becomes quite annoying.
$ strace -fF -e trace=all audacity shows that it waits several more seconds for this JACK (although it is clear straightaway that it can't be started): socket(PF_FILE, SOCK_STREAM, 0) = 7 getuid32() = 502 connect(7, {sa_family=AF_FILE, path="/var/lib/jack/tmp/jack-502/default/jack_0"}, 110) = -1 ENOENT (No such file or directory) close(7) = 0 clone(Process 12488 attached child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0xb6a89928) = 12488 [pid 12488] clone(Process 12489 attached child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0xb6a89928) = 12489 [pid 12489] open("/home/ivan/.jackdrc", O_RDONLY) = -1 ENOENT (No such file or directory) [pid 12489] open("/etc/jackd.conf", O_RDONLY) = -1 ENOENT (No such file or directory) [pid 12489] execve("/usr/bin/jackstart", ["/usr/bin/jackstart"..., "-T"..., "-ndefault"..., "-T"..., "-R"..., "-d"..., "alsa"..., "-p"..., "512"...], [/* 70 vars */]) = -1 ENOENT (No such file or directory) [pid 12489] dup(2) = 7 [pid 12489] fcntl64(7, F_GETFL) = 0x2 (flags O_RDWR) [pid 12489] fstat64(7, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 2), ...}) = 0 [pid 12489] mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb6a36000 [pid 12489] _llseek(7, 0, 0xbfb29b98, SEEK_CUR) = -1 ESPIPE (Illegal seek) [pid 12489] write(7, "exec of JACK server failed: No s"..., 54exec of JACK server failed: No such file or directory ) = 54 [pid 12489] close(7) = 0 [pid 12489] munmap(0xb6a36000, 4096) = 0 [pid 12489] exit_group(99) = ?

Могу собрать 1.3.5 без данной проблемы и поддержки Mpeg 1 Layer 3 хоть сегодня. Устроит?
(In reply to comment #3) > Могу собрать 1.3.5 без данной проблемы и поддержки Mpeg 1 Layer 3 хоть сегодня. > Устроит? Спасибо за отклик! Я не совсем понял, потеряет ли такая сборка какие-то полезные свойства или действительно просто исправит эту неприятность. Если потеряет полезные свойства, то не надо, нужно более правильное исправление тогда. (Просто исходя из здравого смысла, в 21-ом веке программе не нужно 5 сек ждать, чтобы узнать, что на этом же компьютере какая-то программа не запустится, потому что её нет.)
Mpeg 1 layer 3 блоее известен как mp3. Не то чтобы сверхважная штука, но отсутствие поддержки этого формата вызовет недовольство, мне кажется.
Прошу тестировать audacity-1.3.5
На 2.0.x у меня не наблюдается.
