document whether module-loopback uses resampling
The documentation for module-combine-sink mentions that a potentially CPU-intensive adaptive resampling is performed to compensate between different crystal frequencies associated with each output sink:

However, I could only find resampling mentioned in the documentation for module-combine-sink. It would be relevant, for example, to a user of module-loopback, to know whether adaptive resampling occurs, or whether the source and sink are allowed to gradually drift apart:

Thanks.
