Interestingly, I stumbled across another case where s24_le data produces noise. Playing that sample on Windows with vlc also fails! Now, what does xbmc under Linux on a pi have in common with vlc under windows on a pc? ffmpeg/libav...
s24_le.wav plays as noise on Pi with xbmc with analogue/hdmi output.
Also plays as noise on Ubuntu with xbmc, vlc or mplayer.
Audacity shows the file as very quiet. I was only able to hear/see the "testing 1,2,3,4" after running a normaliser to amplify the sound (and it played okay).
Not sure if the 24-bit playback issue is the same issue as the 24-bit ALSA.
Note: I have 24-bit files in other formats that xbmc handles correctly.
