I am a little confused about your advice. I am not sure how to access the 'plughw' device from my application. I have a full duplex application that can play a file at 44.1kHz and record at the same rate but I want it to operate at lower sampling frequencies. I am not sure of how I should be setting up my PCM devices. How do I tell them to convert, say, 8kHz audio data to 44.1kHz audio data so my hardware can play it at the correct speed? I tried using aplay with plughw to play an 8kHz file and got the following results >aplay -Dplughw s1.wav Playing WAVE 's1.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono Segmentation fault However it worked when using a 441.kHz file.
