We answered it there, in public, and this is the fuller\nversion. It is a good example of a problem that looks like a missing driver and is actually\ntwo separate failures stacked on top of each other.\u003C\u002Fp>\n\n\u003Ch2>The short version\u003C\u002Fh2>\n\n\u003Cp>The Echo Link Amps are not passive. They are powered amplifiers with their own DAC and\nvolume stage. What looks like one problem — \"it shows up but no music plays\" — is two:\nControl4 has nothing to talk to, \u003Cem>and\u003C\u002Fem> there is probably no audio physically reaching\nthe amps. Neither one is fixed by a driver.\u003C\u002Fp>\n\n\u003Ch2>The question\u003C\u002Fh2>\n\n\u003Cp>Someone was adding four Amazon Echo Link Amps for multi-room music on a Control4 system\nrunning OS 4.2 with two CORE 1 controllers and two Neeo remotes. There is no specific\ndriver, so they tried generic ones. The amps \u003Cem>appeared\u003C\u002Fem> in the system but no music\nplayed through them. Their own guess was that the amps being passive meant no signal was\nbeing registered — reasonable, and not quite right.\u003C\u002Fp>\n\n\u003Cp>The rest of the music group is two Sony STR-AZ3000ES receivers. The test source was the\nAmazon Music app added to Control4.\u003C\u002Fp>\n\n\u003Ch2>Our answer\u003C\u002Fh2>\n\n\u003Ch3>Failure one: there is nothing for Control4 to control\u003C\u002Fh3>\n\n\u003Cp>The Link Amp is driven by Alexa. As far as we know Amazon never published an IP or serial\ncontrol interface for it, which means there is no protocol for a driver to speak. That is\nwhy a generic amp driver binds happily and gives you a nice icon and does nothing — the\ncommands go out and land nowhere.\u003C\u002Fp>\n\n\u003Cp>Worth doing your own search on driverCentral before taking our word for it, but we have\nnever seen a Link Amp driver from Chowmain or anyone else, and we would not expect one to be\npossible without a published control interface.\u003C\u002Fp>\n\n\u003Ch3>Failure two, and this is the one that explains the silence: no audio path\u003C\u002Fh3>\n\n\u003Cp>This is the part that matters most and it is the part people skip.\u003C\u002Fp>\n\n\u003Cp>In Composer, selecting a source in a room only produces sound if that room's audio\nendpoint is bound — in the \u003Cstrong>Connections\u003C\u002Fstrong> tab — to something that physically\ncarries the signal to that amplifier. Control4 will happily show a source as selected in a\nroom and route exactly zero audio, because as far as it is concerned it did its job.\u003C\u002Fp>\n\n\u003Cp>The original poster confirmed the diagnosis himself in a follow-up: no sources were\nconnected to the Link Amps at all. So even with a perfect driver, there was no signal to\nplay. Open the Connections tab on the generic driver and look at what its audio input is\ntied to. If it is tied to nothing, that is your answer, and no driver is going to fix\nit.\u003C\u002Fp>\n\n\u003Ch3>The real problem is architectural\u003C\u002Fh3>\n\n\u003Cp>Echo Link Amps are designed to pull their own stream from Alexa over the network. They are\nnot a Control4 endpoint. They are a parallel music system that happens to live in the same\nhouse.\u003C\u002Fp>\n\n\u003Cp>You can force it to sort-of work: feed a fixed analog or optical output from a matrix into\neach amp's input, set the Link Amp volume once, never touch it again, and do all level\ncontrol upstream. But then you have four amplifiers nobody can turn down from a keypad, and\na second app in the house for the family to be confused by. We would not build that for a\nclient.\u003C\u002Fp>\n\n\u003Ch3>What we would actually do\u003C\u002Fh3>\n\n\u003Cp>Pull them and put in four \u003Cstrong>Sonos Amps\u003C\u002Fstrong> or \u003Cstrong>Triad Ones\u003C\u002Fstrong>.\u003C\u002Fp>\n\n\u003Cul>\n  \u003Cli>\u003Cstrong>Sonos Amp\u003C\u002Fstrong> is what we would pick for a retrofit like this. The driver\n  is official, the streaming is native, and the client gets transport and volume on the\n  touchscreen and the keypad without anybody building anything custom.\u003C\u002Fli>\n  \u003Cli>\u003Cstrong>Triad One\u003C\u002Fstrong> is the cleaner answer if you want everything inside\n  Control4's own streaming and do not care about the Sonos app.\u003C\u002Fli>\n\u003C\u002Ful>\n\n\u003Cp>The two Sony AZ3000ES receivers are fine and stay exactly where they are — that is a real\ndriver over IP and it works.\u003C\u002Fp>\n\n\u003Cp>We should flag our own hedges: the specifics above about what the Link Amp does and does\nnot expose, and about current availability of the Triad One, are from our experience and our\nrecollection rather than from a spec sheet open in front of us. The architectural point —\nthat these are an Alexa endpoint and not a Control4 one — is the part we are confident\nabout.\u003C\u002Fp>\n\n\u003Ch2>What others said on the thread\u003C\u002Fh2>\n\n\u003Cp>\u003Cem>Summarised in our words. These are other people's claims on a public forum, not ours,\nand we have not verified them.\u003C\u002Fem>\u003C\u002Fp>\n\n\u003Cul>\n  \u003Cli>\u003Cstrong>u\u002Fremeolb\u003C\u002Fstrong> asked the right diagnostic questions before offering any\n  answer — what is the audio source for the Sony AVRs, are any sources connected to the Link\n  Amps, what OS and hardware. That is exactly the order we would work in, and it is what\n  surfaced the missing audio path.\u003C\u002Fli>\n  \u003Cli>\u003Cstrong>u\u002FCircuitDaemon\u003C\u002Fstrong> gave the answer the poster ultimately took: if you\n  want Control4 to be the audio source you need an audio matrix, and pointed at the Control4\n  Audio Matrix Switch V3 (16 stereo inputs, 16 outputs) — controller connects over RCA, then\n  each output is assigned to a zone. They also offered a Sonos Port per amp as the\n  alternative, which would make each amp a Control4-visible source and let grouping work\n  through either the Control4 driver or the Sonos app.\u003C\u002Fli>\n  \u003Cli>\u003Cstrong>u\u002FFrozenHoser\u003C\u002Fstrong> questioned whether the poster was a dealer or an end\n  user and suggested talking to a dealer either way.\u003C\u002Fli>\n\u003C\u002Ful>\n\n\u003Cp>The original poster said the matrix explanation was what he needed. We would add only\nthat a matrix and our recommendation are not in conflict — a matrix solves the audio-path\nhalf; it does not give you volume control at a keypad on the Link Amps, because that half\nhas no protocol to work with.\u003C\u002Fp>\n\n\u003Ch2>What we would need to answer this for your house\u003C\u002Fh2>\n\n\u003Cp>If you are looking at a rack and cannot tell whether you have a driver problem or a wiring\nproblem, send us:\u003C\u002Fp>\n\n\u003Cul>\n  \u003Cli>What is physically feeding the amps right now\u003C\u002Fli>\n  \u003Cli>What matrix or switch is in the rack\u003C\u002Fli>\n  \u003Cli>What the Connections tab shows for the amp's driver\u003C\u002Fli>\n\u003C\u002Ful>\n\n\u003Cp>We will tell you whether there is any path worth chasing or whether you are simply buying\nnew amplifiers.
