    You could try this code. It uses ioctl with the request field as KIOCSOUND.

    Thank you for the help, but I think I didn't explain propertly what I'm looking for. I'm writing a code in c++, in which I want to introduce a function to play a beep. Like, for example, when you press a key, a beep sounds. I tried to print "\a" and "\7". It works in windows, but not in linux, so I thought I could try to find some library with a function that could do that for me.
    This code seems to be meant to be installed and used from the command line. I have been reading it, and my level of knowledge is not enough to make a function using it. So, I made a little of google search about printing "\a". But I don't know why it isn't working. I'm actually emulating ubuntu-11 in Oracle VM VirtualBox, so could be because of that, but I couldn't find why it doesn't work. Can anyone gave me some directions or a pointer to where pages should I look for to just be able to play a "beep", or at least to understand why a simple (cout<<"\a"; ) doesn´t work??
