This does not tell me anything. I have often had problems 
with ALSA in the past. I think it is because alsa-oss is
not given much attention by the developers - they provide
it for lazy people with old softwares who are (like me)
reluctant to rewrite for the ALSA interface.

I installed the latest Debian testing a couple of days ago.
It came with alsa but without alsa-oss and it works perfectly
well on the laptop. On the stationary computer I have the
stable release of Debian and it uses OSS since the alsa
plus alsa-oss package did not work properly. 

The (non-working) stationary has SND_LIB_VERSION_STR = "1.0.13"

The well working lap-top does have the /dev/sndstat file:
hp:/home/dsp# cat /dev/sndstat
Sound Driver:3.8.1a-980706 (ALSA v1.0.14rc3 emulation code)
Kernel: Linux hp 2.6.21-2-686-bigmem #1 SMP Wed Jul 11 05:05:14 UTC 2007
i686
Config options: 0

Installed drivers:
Type 10: ALSA emulation

Card config:
HDA Intel at 0xe8580000 irq 20

Audio devices:
0: AD198x Analog (DUPLEX)

This was all automatically installed with the standard packages
for Debian. There is no longer any alsa-oss package and Linrad
compiles and runs without any problem under X11.

(It is quite another thing that I had to modify both mousetest
and the linrad main routine in order to make the screen work
properly. These changes will come with Linrad-02.39)
(There will also be a proper error message rather than a 
seg-fault in an error situation like the one you have right now:
[1289]routine:set_analog_io    file:lsetad.c
No usable device found for loudspeaker output.)


It seems to me you should de-install alsa and alsa-oss and then
install ALSA v1.0.14rc3. Maybe that would help.
