Hello!
This Emacs runs on an i810 (audio etcetera) chipset. This (Debian)
Emacs 21.3 refuses to play a 'wav' file. Stubborn!?
play-sound-file file.wav gives 'Could not set sound format'
But (for example)
Welcome to the Emacs shell
~ $ play file.wav
works
Why!? Does Emacs handle sound by its own, bypassing the OS?
Thanks
Gijs

I don't know what you meant by ``bypassing the OS''. Emacs uses the
OS interface to the sound device (ioctl, write, etc. system calls),
but if you were asking whether it calls the `play' utility internally,
then no, it doesn't. However, the system calls Emacs issues to play
the sound are supposed to be the equivalent of what `play' does.

Thanks Eli,
Rephrasing the question, any idea of why this (Debian) emacs won't
play this sound file?
Regards

Why don't you ever enter any CONTESTS, Marvin?? Don't you know your
own ZIPCODE?

No idea here. Perhaps you could use the strace utility to find out
what system calls are issued by `play' and by Emacs, and what is the
difference between them.
