Chat with Jon:

(16:08:24) humitos: jnettlet: using this .wav file I have problems...
(16:08:42) humitos: it starts playing something weird and then, Jukebox crashes
(16:10:11) jnettlet: humitos: without looking in depth my guess is one of the waves is at a lower rate than 44100 or 48000 Hz this causing our audio driver to do stepping which sounds horrible
(16:10:36) humitos: jnettlet: ah... I didn't know that our audio driver has that limitation
(16:10:41) humitos: jnettlet: it's a good answer
(16:10:58) jnettlet: humitos: so if we have bad sounding audio that is the first thing to test.  I have some config changes around that do the sampling in software first that we need to implement
(16:11:24) humitos: jnettlet: $ file june_chorus.wav 
(16:11:24) humitos: june_chorus.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 24414 Hz
(16:11:33) humitos: jnettlet: that is the .wav that doesn't work
(16:11:35) jnettlet: yep that would do it
(16:11:58) humitos: jnettlet: but this one... DOES work
(16:12:00) humitos: $ file thermo.wav 
(16:12:00) humitos: thermo.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, mono 11025 Hz
(16:12:49) jnettlet: well the 24414 is a really strange rate.  11025 at 8 bit we can mostly handle if the sound isn't too complex
(16:14:02) humitos: jnettlet: it doesn't seem to be complex... it's just a man voice :P
(16:14:20) ***humitos is wondering about the meaning of "complex"
(16:14:28) jnettlet: regardless CC me on the bug and I will dig up my .asoundrc that forces software resampling before sending it to the hardware.
(16:15:13) jnettlet: humitos: there is an open bug from Quanta about one sample in one of the activities that also sounds "strange" I bet it is the same problem.
(16:15:44) humitos: jnettlet: ok, so... is not a problem that I can attack and fix...
(16:17:35) jnettlet: humitos: you could alter the gstreamer pipeline to force the software resampling, but really I would prefer to do this as an alsa configuration change.  Have gstreamer do what it wants and alsa can resample with speex to something the hardware can deal with
