Description Emanuel Rumpf 2008-06-26 21:44:45 CEST

in the cvs-version of qsampler (or liblscp, etc.)
the volume sliders do not work.

Values of 0 or 100 have effect, but no values between.
This applies to channel volume sliders and global volume slider.
It seems, that volume is muted (or set to 0) for values < 1.

Christian S. suggested setting LANG=C
: "That's a local dependent bug (comma vs. point for decimal separator in
floating point numbers)."

Unfortunatly that had no effect on it, when I tried (recompiled) it.

as soon as dragging the volume slider, it is jumping to the 0
position, with the exception of 100%
so my option is 0 or 100%, but nothing between.

in the qsampler window I see:

22:19:19.320 Channel 0 Volume: 0.74.
22:19:19.568 Channel 0 Volume: 0.74.
22:19:19.616 Channel 0 Volume: 0.75.
22:19:19.656 Channel 0 Volume: 0.76.
22:19:20.000 Channel 0 Volume: 0.77.
22:19:20.017 Channel 0 Volume: 0.78.
22:19:20.032 Channel 0 Volume: 0.79.

...but the sound is muted... (only ON at 100%)

the same happens, if changing the % value in the spin-box (number-box)
of the channel strip

LANG=C is not meant when you recompile, it's meant to be set before launching 
qsampler. However this issue should be fixed proberly, so that this workaround 
is not needed in future anymore. I try to fix it in the next days.
