Package: alsa-base
Version: 1.0.9b-2
Severity: minor
Servus,
alsactl tries to restore the configuration of all cards by searching for
all possible files in /dev/snd/. This cause a very long delay on a 200MHz
CPU at boottime. IMO "alsactl restore" should only restore the
configuration of the cards named in /v/l/alsa/asound.state.
Bye, Jörg.

devfs is long gone (replaced by udev).
Thus closing this old and stale bug report.

alsactl restore takes a long time on a slow devfs machine. The problem
is the following:
open("/dev/snd/controlC1", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/aloadC1", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/snd/controlC2", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/aloadC2", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/snd/controlC3", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/aloadC3", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/snd/controlC4", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/aloadC4", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/snd/controlC5", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/aloadC5", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/snd/controlC6", O_RDONLY) = -1 ENOENT (No such file or directory)
.....
Each of these attempts causes about a 1 second delay on my machine
(P120). I presume this is due to devfs trying to modprobe stuff in the
background.
A more efficient method would probably be to opendir() and scan through
the directory entries to check for existence.
