Win32 waveOut -> horrible distortion

[Dandruff]

seems there's a big problem with the waveout-module. gives me totally distorted sound. using rme hdsp9632 soundcard here. normally it should work with this card, because this card only has mme-waveout-drivers (no directx/wdm-drivers!)

windows only emulates the direct-x-drivers. vlc works in directx-mode, but why not in waveout-mode???

please fix that!


here's the manual for the hdsp9632: http://www.rme-audio.com/english/download/hdsp32w_e.pdf

maybe it helps (supportet output formats ...)

thanks!!!

'fixed' in latest nightly (option to disable float32 under 'modules' -> 'audio
output' -> 'waveout')

[redfiend]

Sincerest appologies for the necropost... but the same issue has resurfaced for me.

Almost identical circumstances.

Disabling float32 does not help. However, if i change from stereo to mono, i get a few seconds of zero distortion. It sounds like someone is tapping play/pause rapidly.
