Sometimes they set the rate shift manually in an attempt to prevent the inevitable drift problems, but of course without 'closing the loop' this will always result in disaster eventually. In the simple requirement of needing to record the output of an audio player app while at the same time listening to it on a real (playback-only) sound card, what should they do? Can this all be handled with off-the-shelf plugins and without any adaptive resampling? The audio player app may only direct its output to 'default', and the audio recording app needs to engage with a driver for its source..? Can a few lines of text placed in asoundrc solve this problem without resorting to the snd-aloop driver? If you could just suggest to me how this would be done, I think a lot of things would fall into place for me...
