I would like to point out that the problem is _not_ in sound card detection.
The detection is just fine. Its just that draksound must follow a strict
policy of having exactly one driver per sound device.
- During _reconfiguration_ of sound, if the user selects a different driver
for the same sound device, the old entry (in /etc/modules.conf) must be
deleted and then the new entry added. Otherwise, there will be two entries
(like the example in this bug report) with different drivers for the same
sound device.
- During sound reconfiguration, it must check that the same sound device is
not being mistakenly taken as a new one. This will avoid the multiple entries
(one with sound-slot-0 and the other with sound-slot-1) for the same audio
device.
1. Basically, a nice way to do is to store the list of current PCI sound cards
in the system. This can be done by:
lspci -n | grep "Class 0401"
Store the "Vendor_number:device_number" in an array. The 1st element is for
sound-slot-0, 2nd one for sound-slot-1 and so on.
2. Next time, draksound is run, check if any of these sound devices has
changed. By change, I mean:
- addition/removal of a card
- exchange of cards
3. Every time /etc/modules.conf is modified for sound, make sure that there is
only one driver per device:
alias sound-slot-$n driver_name
above driver_name snd-pcm-oss (if ALSA)
Naturally, if the driver is changed, the entries for the earlier driver must
be deleted as well.

Using mandrake-9.1rc1. I have via686b on-board sound. The entries for sound
in /etc/modules.conf are:
above snd-via82xx snd-pcm-oss
alias sound-slot-0 snd-via82xx
alias sound-slot- via82cxxx_audio
The 3rd entry is just plain wrong and should not be there.
