sound module: /dev/audio: Device or resource busy
hello,
i am experiencing strange behavior when attempting to load sound
support as a module. i have a debian 1.3.1 system and a SB AWE-64
PNP card, which i have installed using the isapnptools. the fact
that the pnp boards need to be configured before the sound drivers
mandates that sound must be supported by a module, i.e. not included
directly in the kernel. for this reason, /etc/init.d/boot makes sure
that pnp configuration is taken care of _before_ modules are loaded.
things seem to work fine when i do NOT include the "sound" line in
my /etc/modules file, and instead do "insmod sound" manually after
rebooting. however, when i include "sound" or "auto" in /etc/modules,
i get the message
/dev/audio: Device or resource busy
whenever i try to access /dev/audio (or likewise with /dev/dsp).
i have confirmed that there is no conflict with IRQs, and the
output of /dev/sndstat seems to indicate that everything is ok.
(i have included it below.)
does anybody know why the boot-time loading of the sound module
is not working?
phil
output of /dev/sndstat:
