I'm sure most people purchasing this are looking to add this to their A/V receiver. I'll get this out of the way and say that it works perfectly for that situation, it's pretty much plug and play with a little bit of a setup on your phone, or whatever Bluetooth device you're trying to pair with it, such as the Echo or Echo Dot. I bought it for a different reason. If you're like me, you bought an Echo Dot during Prime Day, because why not? The price was attractive. Now, I like the dot, but what I don't like is it's sound quality. I have Amazon Music, and the tinny sound of it's internal speakers just doesn't quite do it for me. Luckily I have an expensive, loud af, 7.1 Sound System to remedy that issue. Through some cable frakensteining, I have my PC's sound route from my PC through my TV, which functions not only as a TV, but a second monitor, which then routes to my A/V receiver.Wouldn't it be great if the Echo Dot would play through my speakers WITHOUT me having to dedicate a single channel to it? In otherwords, while I still hear all my sound on my PC or TV, such as games or movies, wouldn't it be great having the Echo Dot be able to listen to me and say things on the same input? It would. But Amazon still hasn't caught up to the idea that some of us consider our PC's to be outputs, not only input. I'm going to explain how to do this, because for whatever reason Amazon's software refuses to recognize PC's as speakers, only the dot as a speaker. This is why you need this device. Here's the process, it's simple: By default, setting up Bluetooth on the Echo Dot causes the pair to use the dot as the primary speaker. Buy this device to remedy that issue. I'm also assuming you've already paired your echo with the tp link via the alexa mobile app on your smartphone. If not, do this first.Step 1: Plug in the TP-Link Receiver NOT to your A/V receiver but to the mic input of your PC.Step 2: Go into Windows sound settings (The control panel screen)Step 3: Go to Recording Devices Tab.Step 4: Go to Properties of the Recording device you connected your audio cable from the TP Link to the mic jack by right clicking on it. Probably Realtek, unless you have a sound card like I do. In this example, I connected it to my Sound Blaster card, so I'd go to the properties of the respective mic. For a regular PC without a soundcard, it'd likely be your Realtek mic jack on the back of your pc.Step 5: In properties, go to the Listen Tab. Make sure your correct sound device is selected.Step 6: Check the "Listen to this Device" checkbox.DONE! That's it. That's all you need to do to have the Echo Dot work simultaneously in the background while you watch youtube, or play games on your PC, all on the same channel input. Pretty neat huh?I've attached a visual aid to this.NOTE: You sometimes DO need to ask Alexa to either disconnect from the tp link, or reconnect to it depending on whether your motherboard turns on or off during a full shutdown. In my case, before bed or if I turn my PC off (since my motherboard also shuts down) I say "Alex, disconnect from TP Link" and she'll start playing sound from my Echo Dot instead. Then if I turn my PC back on, I say "Alexa, connect to TP Link" and voila, back in business.Hope this helps, I had a bit of an annoying journey trying to get this to work, so my pain will hopefully translate to your ease of mind. Hope you guys found this helpful!As for the device itself? So far so good. Audio quality isn't perfect, but that's a bluetooth limitation, not a device limitation.Protip: Adjust the mic volume levels to coutner any distortion you hear, also turn off ANY and ALL mic effects you might have on, or alexa will sounds like she's downing underwater. Don't torture Alexa.
