Sure. You can use Multi-Instrument together with a sound card with at least two input channels and one output channel to do it, as shown in the diagram below.

The test signal output to the speaker should be looped back to one input channel as the time reference. The other input channel should be connected to a mic to capture the live sound streamed from the network.
Cross Correlation function of Multi-Instrument can be used to measure the time difference between the two input channels, if the test signal is a wide band signal such as white noise and MLS.
Generalized Cross Correlation function of Multi-Instrument can be used instead for test signals that are not that "white", such as music and speech.
The loopback cable can be physical or virtual. Some sound cards feature a built-in software loopback switch. Once turned on, the output stream will join in the input stream linearly, and the final input will the sum of both. As both output channels will be looped back, the output signal looped back to the mic input should be set to 0 to effectively disconnect this route of loopback, leaving only the other pair of input and output channels connected as a loopback (see figure below). In this regard, VT RTA-268A/B (
