I answer to myself, JFTR:
For some reason SoundPool were unable to load a wav sample that in fact
works in every other player that I have used. So I simply ended using
another file with a different format. Here is the format of the
offending file, as told by mplayer on my GNU/LiNUX box:
|Opening audio decoder: [pcm] Uncompressed PCM audio decoder
AUDIO: 96000 Hz, 1 ch, s16le, 1536.0 kbit/100.00% (ratio: 192000->192000)
Selected audio codec: [pcm] afm: pcm (Uncompressed PCM)
|
And here it is the one for the other file that does work:
|Opening audio decoder: [pcm] Uncompressed PCM audio decoder
AUDIO: 22050 Hz, 2 ch, s16le, 705.6 kbit/100.00% (ratio: 88200->88200)
Selected audio codec: [pcm] afm: pcm (Uncompressed PCM)
|
There are many differences, but the point is that the second works, so I
simply discarded the first one and move into the second. Knowing this if
I needed the first sound sample, I just need to adjust its rate and
channels with an audio editor like Audacity to solve the problem.
Why it did not just work in first case? Who knows, but if I can solve it
so easy... who cares at all?
