Meaning that files I recorded with arecord could be played back by aplay, but not in any other application I tried, such as Audacity. I can try to dig out the gory details, but ISTR it came down to the header(s) in the .wav file being incorrectly filled in with regard to number of bits per sample vs valid bits per sample. /Ricard -- Ricard Wolf Wanderlof ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30
