      • 165. Re: Cirrus Logic Audio Card working on the Raspberry Pi 2

        Hello All I have a question/problem..

         

        I am running the Cirrus Logic Audio Card with a Raspberry Pi 2b

         

        I want to use the rpi as a digital filter. Therefore I use pyaudio to open a stream and within the callback function to filter.

         

        Right now I have the problem that after around 5 seconds I get an "ALSA underrun occured" error, could you imagine how this is possible? Or how do I create this error? Checked it with an audio analyzer (at my university) the filtering works but only for a few seconds...

         

        Trying to google underrun occured raspberry didnt bring up any clues...
