Description Raymond Jennings 2016-01-20 09:02:33 UTC
By tweaking /etc/asoundrc.conf, I was able to ramp the sample rate up and down...and freedroidrpg's output rate stayed the same, causing sound pitch to be warped out of line.

Reproducible: Always

Steps to Reproduce:
1.  use dmixer and tamper with the sample rate, reboot as needed
Actual Results:  
sound is too high in pitch, freedroid probably naively assumes that the audio output device is always at 44.1k

Expected Results:  
freedroidrpg would adjust its output rate to match that of the device

alsa sound configuration

Everything sounds ok when I have it at 44100, but everything sounds like a minor overdose of helium breath if I peg it back up at 48000

nothing to be done here.  it's using sdl-mixer which doesn't support resampling.  the game hard-codes the frequency to be 44100.
