Well, this *should* result in exactly the same behavoir.. Make sure
you have set the right sample format with actrl before...

Well, get the original archive then.

Then your machine is too slow to play at 8kHz. I don't know if s3mod's
limit (8kHz) is arbitrary (then I could remove it) or if it is relied
upton somewhere in the source. Will check this...

Don't know about the Mint Screensaver.

Yes, your machine is too slow for the selected play rate. Pitty s3mod
sets this 8kHz limit.

You can as well use Fcntl(). Mintlib's ioctl() does itself call Fcntl().

Well, you would have to implement all the network protocols into a loadable
file system for, which I won't do (nor probably anybody else), because it
is an enourmous amount of work for which I don't have the time.
