Fix per-source consumed byte accounting in mux_process(). When MUX inputs use different channel counts, using the first input buffer frame size for all consumed accounting advances other source buffers incorrectly. This causes duplicated samples, incorrect output frequency, and capture duration issues. Compute consumed bytes per input buffer using each source stream's own frame size.

Pull request overview
Fixes incorrect per-source input buffer consumption accounting in mux_process() when mux inputs have different channel counts, preventing buffer drift that can lead to duplicated samples and timing/capture length issues.
Changes:
- Removes the single
source_bytescalculation derived from the first input stream. - Computes
consumedbytes per input buffer using that source stream’s own frame size. - Keeps sink production accounting (
sink_bytes) unchanged.
