I've used AL for some time to perform x/o and room eq duties for a DIY speaker with great effect. My perennial question, however, is whether there is a set of stable hardware that would allow me to use the system for other (A/V) sources. Is there, for example, there a path to using the filters etc. when the source is an Apple TV via HDMI or (Optical) S/PDIF that is stripped from the HDMI? I've explored this idea in the past and there seemed to be some options that involved routing an audio input to pro-audio interface to a computer for convolution but it never came across as being a bulletproof set-up that could be used by the family. The ideal thing would be a h/w until that just works but assuming that that is a leap to far then a computer OS + S/W build that works with an external audio interface might be the answer. Any suggestions? How are others dealing with (multi-channel) AL with sources other than Roon?
