    Here's what shows in kernel 2.5.10. I'm using a Soundblaster PCI 512 and I
    have ALSA support for it installed.

    gettimeofday({1019717263, 731947}, NULL) = 0
    select(8, [3 4 6 7], NULL, NULL, {0, 0}) = 2 (in [6 7], left {0, 0})
    read(7, 0x809fa74, 8192) = -1 EBADFD (File descriptor in bad
    state)
    dup(2) = 8
    fcntl64(8, F_GETFL) = 0x2 (flags O_RDWR)
    fstat64(8, {st_mode=S_IFCHR|0620, st_rdev=makedev(3, 1), ...}) = 0
    ioctl(8, SNDCTL_TMR_TIMEBASE, {B38400 opost isig icanon echo ...}) = 0
    old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)
    = 0x40014000
    _llseek(8, 0, 0xbffff5e4, SEEK_CUR) = -1 ESPIPE (Illegal seek)
    write(8, "read sound: File descriptor in b"..., 41read sound: File
    descriptor in bad state
    ) = 41
    close(8) = 0
    munmap(0x40014000, 4096) = 0
    _exit(1) = ?

    Here's what shows in kernel 2.5.6-pre3 until I pressed control-C.

    gettimeofday({1019718466, 876979}, NULL) = 0
    select(8, [3 4 6 7], NULL, NULL, {10, 631024}) = 1 (in [7], left {10,
    600000})
    read(7, "\377\377\1\0\377\377\2\0\2\0\376\377\376\377\0\0\375\377"..., 8192)
    = 8192
    gettimeofday({1019718466, 922638}, NULL) = 0
    ioctl(3, 0x541b, [0]) = 0
    gettimeofday({1019718466, 923415}, NULL) = 0
    select(8, [3 4 6 7], NULL, NULL, {10, 584588}) = 1 (in [7], left {10,
    540000})
    read(7, "\0\0\377\377\0\0\6\0\2\0\377\377\1\0\3\0\376\377\375\377"..., 8192)
    = 8192
    gettimeofday({1019718466, 969320}, NULL) = 0
    ioctl(3, 0x541b, [0]) = 0
    gettimeofday({1019718466, 970109}, NULL) = 0
    select(8, [3 4 6 7], NULL, NULL, {10, 537894} <unfinished ...>
