I'm experiencing some problems with the sound module under 2.0.33.
Basically what happens is that even though the sound module is ok at
startup (all the devices are reported correctly and functioning
properly), once the module gets removed (by either kerneld or "by
hand"), reloading the module will not work as expected. While the
module itself loads, some of the devices are missing (notably the
audio devices, the midi devices and the mixers.
Is this a known problem? I am running RedHat 5.0, kernel 2.0.33 SMP,
a Tyan Tiger 2 motherboard w/ 2 PentiumII/233, AWE64Gold PnP soundcard
(configured with pnpdump/isapnp). I have tried with and without the
awe64 0.4.2d driver - same behaviour.
Here is the relevant configuration from my kernel configuration file:
CONFIG_SOUND=m
