If the sample rate is lower, you need more timer to play the same numberof samples. > frames = snd_pcm_writei(handle, buffer, sizeof(buffer)); The last parameter is measued in frames, not in bytes. When you useanother sample format than U8/S8 or more then one channel, you have todivide the buffer size by the number of bytes per frame.
