Description Reuben Thomas 2003-06-16 00:18:56 UTC

Version:           2.2.1 (using KDE 3.1.2)
Compiler:          gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
OS:          Linux (i686) release 2.4.20-13.9

When I play .wav files in noatun that are 16-bit stereo 44.1KHz samples, they are played approximately a semitone sharp (slightly more, as far as I can tell). I estimate that they're playing at 48KHz. If I play them using play (sox) or xmms, they are played at the correct pitch.

In KControl->Sound and MM->Sound System, Sound I/O tab, set the samplerate to 48000 (and 
also try forcing 44100 if that doesn't work). 
 
I don't know if this will fix it, but it might.

Sorry, this was a config problem. I had "custom sampling rate" selected, I think a setting left 
over from my previous laptop (it says "you may need to set the sampling rate to 48000 for a 
Yamaha sound card", which I had on my last laptop). 
 
I don't use sound players very much, at least, not demanding that they be precisely in tune!

The human ear is very sensitive to even a very small change in frequency, 
actually :)

I find it odd that this would be a problem, aRts should just resample it 
differently. Oh well.
