I've installed alsa successfully a couple of times, but this latest
time, I have a problem that I can't track down. Any help would be most
appreciated.

This is a Debian testing system. The kernel is (hand-compiled) 2.4.23
with the ck1 patches for increased responsiveness. The sound card is a
Turtle Beach Santa Cruz. 

I installed alsa-driver, alsa-lib, and alsa-utils from source. The
version for all of them is 1.0.0rc2. I compiled with the recommended
options for the card (--with-cards=cs46xx --with-sequencer=yes etc)
The compilation and installation were completely smooth---no errors or
complaints. 

But when I try as an ordinary user:

  aplay amazed.wav

I get:

   aplay: main:502: audio open error: Permission denied

Also:

  [toraigh] aplay -l
            aplay: device_list:201: control open (0): Permission denied

The permissions on the audio device are what they are supposed to be,
I think:

  lrwxrwxrwx    1 root     root            9 Dec 11 15:24 dsp -> /dev/dsp0
  crw-rw----    1 root     audio     14,   3 Dec 11 15:24 dsp0
  crw-rw----    1 root     audio     14,  19 Dec 11 15:24 dsp1
  crw-rw-rw-    1 root     root      14, 163 Jul 20  2001 dsp10
  crw-rw-rw-    1 root     root      14, 179 Jul 20  2001 dsp11

I am a member of the group `audio':

  [toraigh:~] groups jim
              jim : jim disk dialout fax cdrom floppy audio dip video

Aplay run by root plays the file fine.  More weirdly still, the
problem seems to be specific to aplay, since wavp and xmms both play
the file fine when run by an ordinary user.

How might I troubleshoot this problem?

Thanks,

Jim
