hi!
some time back there has been a similar bug report about the same
problem:
http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg01675.html
with no response ... so i will be a bit more verbose :)
it have this problem on all computers (Athlon, P3, P4, Cleron) i have
access to. all of them have different sound cards (SB128, SB Live, AC97
Via686 and AC97 on a i845) and on all of them i have used various 0.9
betas of alsa and versions of the linux kernel (2.4.5 to 2.4.18).
no problem with the oss driver
i have done a strace run of rtcw and found some interesting things:
somewhere rtcw opens the dsp device:
open("/dev/dsp", O_RDWR) = 16
but i cant find the coresponding
close(16)
this are the last lines of output (process locks here):
write(2, "----- CL_Shutdown -----\n", 24) = 24
write(2, "-----------------------\n", 24) = 24
fcntl64(0, F_GETFL) = 0x802 (flags
O_RDWR|O_NONBLOCK)
fcntl64(0, F_SETFL, O_RDWR) = 0
write(2, "Shutdown tty console\n", 21) = 21
ioctl(0, SNDCTL_TMR_STOP, {B38400 opost isig icanon echo ...}) = 0
_exit(0) = ?
i dont know much about kernel internals - but isnt _exit a kernel syscal
that is supposed to close all open devices?
so what kind of bug is this? rtcw? alsa? kernel?
this is a very anoying bug for me and it would be nice if someone could
help me with this problem. i have even mada a panel button to kill the
hanging processes :)
tia,
michael.
