Dear all! When I have multiple hw audio (or other) sources and sinks gnuradio is suffering from the "two clock problem".
>From the docs I have read, one means to mitigate against under- or over- runs is to have the sender always be a little faster. While I understand that this will help keep the sink always filled it will not avoid buffer under runs, or am I misunderstanding something? Also the only way for the source to keep up is to throw away samples at times. Has anyone came up with an idea of how this problem could (should) be addressed in a proper way in gnu-radio? (I mean without changing hw.) >From a little test set up I have seen that I could program a sink and a source, referencing a common buffer. The buffer level (a smoothed version) could be the driving variable to a dynamically programmed sample rate converter that is set up so as to keep the buffer level constant. Is this a too hakish attempt to address the problem? Has anyone already tried this? Is there a more straight forward way, i.e. using a regular input-output module? I am thankful for any hints or comments.
