Here are the most common problems and associated workarounds for recent releases:




14.0.0 on (k)ubuntu Hardy (8.04): "sox soxio: Failed reading `some.file': unknown file type `auto'" (or other file-type).

Install the missing file types with: sudo apt-get install libsox-fmt-all


14.2.0 on unix-like OSs, when building SoX from source, the 'configure' script fails on some systems causing a subsequent make error similar to:

Temporarily remove or rename /etc/issue, or apply the patch in the bug report, and re-run the configure script.


14.2.0 on Vista OS: "normalise: cannot create temporary file: permission denied" (can also occur with other effects)

`The temporary files problem turned out to be a Vista security issue. By using the SoX properties to adjust permissions, and turning off User Account Control (the annoying new thing where Vista pops up a message asking if a program should do what you just told it to do....), I got the effect to work just fine.'


14.2.0 on any Windows OS: "normalise: cannot create temporary file: No such file or directory" (can also occur with other effects)

Create a folder called `tmp' at the top level of the `C:' drive (and any other drive from which SoX may be invoked).


14.4.0: "can't open output file 'default': can not open audio device: Connection refused" when trying to play back audio

Either install the PulseAudio sound server, or override this default by setting AUDIODRIVER=alsa (or oss, or other desired audio driver). On Debian/Ubuntu, removing the libsox-fmt-pulse package also helps.

Please report any new bugs here.
