Ask an audio question? -- Linux general technology-Linux programming and kernel information. The following is a detailed description. I used fedora6. I just wrote a sound playing applet.
This program is to make some simple control on the playing sound, adjust the volume, switch the sound and so on, now the basic functions have been achieved, but there is still a small problem. that is, when the sound is disabled, the response is not timely enough. my approach is to use the close () function to close the dsp device (the device name may be different in different versions). I don't know if there are other methods to cut the sound playing in time.
I see in sound. there are many Macros in the H file, but I don't know the meaning of each one. I guess there may be ways to immediately close the sound. Please give me some advice...
