Description Bryce Nesbitt 2001-05-21 21:25:43 EDT
Description of Problem:
Sad but true.  Sox 12.17.1, as supplied with RedHat 7.1 can't record
correctly.  This means the "rec" command is broken also.  Also broken are
the many programs that use sox
as a backend.

How Reproducible:

Steps to Reproduce:
1. 	"rec test.wav"
2. 	Try to press control-C
3. 	Nothing happens
4.	Use "rec -r 44100 -s w test.wav" to force a 16 bit CD quality recording,
	in case the above does not hang for you.  12.17.2 hangs on both
	versions.  12.17.1 seems to only hang on the second.

Additional Information:
Chris Bagwell <cbagwell@sprynet.com> has already been notified, and has
fixed the problem as of the next release after 12.17.2.  He says:

	"Just tracked down that problem and spent a few hours rewriting the
	reading functions in raw.c to fix it and prevent future bugs in the same
	area from creeping in.  Its in CVS."
Comment 1 cbagwell 2001-05-24 14:13:30 EDT
It will be a month or two before I can test sox 12.17.2 (or 12.18) enough to
make a release.  I believe the following will also work as a valid solution
until the next release.  You may wish to add this to your distributed

Edit the file raw.c in sox, find the function blockr(), look for

ft->file.eof = (ft->fcount < n);

change the "=" to a "|=".

Will be fixed in 12.17.1-4; thanks!
