Could you give me an example of how I can ask the PCM file plugin to write to a named pipe? Should i create this manually or can I somehow do this via the PCM file plugin itself by using the '|' character? Also, don't named pipes block until there is a reader? Given that I've only been able to do this via .asoundrc (and not via the snd_pcm_file_open), I'm not sure how the blocking behaviour would interact with ALSA. Would only my file plugin PCM definition block while others continue? Regardless, thank you for the suggestion. I will try this out meanwhile.
