Comment 4 for bug 2058691

I think sof-mtl-rt711-4ch.tplg and sof-mtl-rt711.tplg aren't the same thing. I'm guessing the former is for devices with four audio channels? I'm on arch with a sof-mtl-rt711-4ch.tplg and another file beginning with "sof-mtl-rt711", but no "sof-mtl-rt711.tplg". Renaming either of them to sof-mtl-rt711 produces the same error. Also, googling "sof-mtl-rt711" reveals an internal Intel document mentioning the existence of this file, so I'd imagine Intel hasn't released the file yet.
