Thanks but I checked that. The permissions are correct I think:

$ ls -l /dev/dsp
-rw-------  1 norm root 0 Jun 15 19:08 /dev/dsp

The problem occurs when an ioctl is done on the sound device. If I do a:

strace -f play info.wav

I see later:

[pid 32345] open("/dev/dsp", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 4
[pid 32345] ioctl(4, SNDCTL_DSP_RESET, 0) = -1 ENOTTY (Inappropriate ioctl for device)
Hence the 'Unable to reset OSS driver" message.
