I work in IT, and agree with other comments about a software bug! In itself, shouldn't be to big a deal, providing that is, the company are willing to work on software update. I guess you could ask yourself, "work on a fix and make no money?" Or, "sell another product?"
In my humble opinion, it makes perfect business sense not to try and fix a fault after some 1 to 2 years of use. I had same issue with Fitbit Blayze, just crept over the 2 year warranty window and it refused to turn on. I thought I could replace the battery - wrong! For some unknown reason the battery had been soldered to the unit making it practically impossible to replace. I wonder why they do that, I thought to myself, then I realised ;)
If it does help anyone, I can connect to a blue tooth speaker and use it that way. I just happened to have a spare speaker not being used. I wouldn't go and buy one, for that, you may as well buy another Echo. Funnily enough though, it does not work when connected to a speaker using an audio cable :)
I have the same problem with a black first gen echo; it hears voice commands, but doesn't respond. It happens intermittently. Sometimes a day or a week will go by without the problem, but never more than a few weeks. This problem was evident within the first few months after purchasing. Reading all that others have said, it's definitely an inherent problem. I'd venture to guess that Amazon knows what it is, or else the problem would continue to plague their latest echo devices.
........ so here is a suggestion that has just worked for me. I initially connected to a speaker using the 3.5 connector plug. I then found that as I removed the plug from the Echo the sound came through. Hope this helps someone else.
Having this issue straight out of the box. Just got my first echo dot and trying to get it working. It wakes up with a blue light then changes to an alternating green and blue light but no sound. Volume is up, it connected to wifi, and the Alexa app on my Samsung s10e.
Add me as another notch in the belt of afflicted users. All we do is use the echo to play music. A single feature, the simplest available, yet we still can't use it. For this to be an ongoing issue by "the world's most customer centric company" is extremely frustrating and discouraging... If anyone finds a solution beyond resetting or Bluetooth, please post it here so we can help each other since it appears Amazon is in no hurry to do so. 😁
*Apologies for the negative tone. Just not very impressed with Amazon lately.
This may or may not apply to certain devices...but it's worth looking into if your device already doesnt seem to work. Mine is an echo dot from late 2017...whatever generation that is.
I took my echo dot apart tonight after a year of it collecting dust with locked-in syndrome. It knew I was trying to talk to it...but Alexa couldn't talk back. Once into the device...there were two little spring contacts on the board...I took a small knife and gently made sure those were still springy. I took said knife and very carefully scratched the tops of those contacts. On the speaker side, there are also two flat metal contacts. I gently scraped those with that knife til they were shiny again. They looked almost like they had a dirty film on them before.
I put it all back together...she works perfect now.
Just be careful...unplug everything before you start...be careful with Alexas guts... I am not responsible for any damage to you or your property...or your device.

Different types of Fixes are appreciated.

OK this is the fix that worked for me...I have three Echo's in my house and for some reason two of them were paired via bluetooth and at any given time i was having an issue with either one of them (blue light with no sounds mostly but would respond to commands, i.e. controlling thermostat, etc). Unpairing them via bluetooth seems to have fixed this issue for me.
