The `remix` flag for `module-combine-sink` is new in PulseAudio 16.0, so this example won't work with older versions. Please keep in mind that PulseAudio will constantly adjust the sample rate to compensate for the deviating quartzes of the sound devices. This is not perfect, however. Deviations in a range of 1/44100s (or 1/48000s depending on the sampling frequency) can not be compensated. The human ear will decode these deviations as minor movements (less than 1cm) of the positions of the sound sources you hear. ## How can use my Windows box to play the sound from my Linux box? |
