This could be explained by a few things. First, if the sound driver is not
returning the same value on a "get" as the value that was issued by the
last "set", that would do it.
Alternatively, it might be due to another audio app rounding the numbers.
It could also be Xaw3d.
Try this. Build fxtv from ports with these changes.
1) In tvaudioc.c::TVAUDIOSetLineVolume(), put a:
printf( "Set volume: %d %d\n", vol[0], vol[1] );
right before the MIXER_WRITE ioctl.
2) Also put a:
printf( "Get volume: %d %d\n", vol[0], vol[1] );
inside the else clause in tvaudio.c::TVAUDIOResync() (this is after the
MIXER_READ ioctl).
3) In actions.c::TVActionSetVolumeAction(), add:
printf( "TVActionSetVolumeAction: value = %d\n", vol_val );
right before:
TVAUDIOSetLineVolume( vol_val, TRUE );
4) In tvmenu.c::TVTOOLSVolSliderJumpCB(), add:
printf( "TVTOOLSVolSliderJumpCB: value = %d\n", vol );
right before:
TVAUDIOSetLineVolume( vol, False );
This will tell us what values we're sending to the sound driver and
receiving from the sound driver.
