SetSoundVolume
I used SoundVolume() to check the volume setting in my NXT and the result came back as 1, which is what I specified in the NXT menu system. However, when I play a file it is loud. How can I control the volume? The file was one of the "standard" system files, like "! Attention.rso". SetSoundVolume(1) seemed to have no affect.

Not an expert, but a quick trawl though the 'net indicates that you might have to use this (taken from John Hansen's NXC Guide) -
PlayFileEx(filename, volume, bLoop) Function
Play the specified sound file (.rso) or a melody file (.rmd). The filename may be any
valid string expression. Volume should be a number from 0 (silent) to 4 (loudest).
bLoop is a boolean value indicating whether to repeatedly play the file.
PlayFileEx("startup.rso", 3, true);
I think PlayFile just sends the file to the speaker at full volume.

Hello,
In NXCDefs.h you find:
so PlayTone and PlayFile always play at volume 4. Read the volume via SoundVolume() and use PlayFileEx instead of PlayFile.

In NXCDefs.h you find:
Code: Select all
#define PlayTone(_f, _d) PlayToneEx(_f, _d, 4, 0)
#define PlayFile(_f) PlayFileEx(_f, 4, 0)

Re: SetSoundVolume
Ofttimes I amaze myself with my ability to look at a line next to the one I should be looking at and not see the correct line.
Thank both of you.
