    I had the same exact issue today. Apparently it is not a software issue but I am afraid it could be a hardware issue. The quick workaround is play some song/video (with audio) using any app (xbox Music, etc) and then using your fingers press by applying little pressure near the speaker area (the small hole) on the back cover. Please do NOT try this workaround without the backcover (i.e.) or directly on the speaker which is below/near the battery. This may fix the problem since it helped me.

    If you still have the problem then your best option is to contact Microsoft support for warranty repairs - Microsoft Lumia 640 - Warranty and repair - Microsoft - USA

    Good luck

    Is the phone on?
    But no really I'd take the approach above and see if you can get it repaired. Haven't heard many issues with broken speakers with this phone so my guess is you got a bad apple unfortunately. :/

    Switching off then turning it on may work, NL625 & NL630 do that when you insert headphones then take them out...

    Microsoft mobile told me to try the "Software Recovery Tool" which I did and that didn't work. I think you're right. It's a hardware problem. I'm sending mine in to get fixed.

    I guess this is somethin like the Asha 300 touch screen issue were you screen becomes totally unresponsive and you have to press the upper right corner in order to get it work. So it's nothing new for those phones I guess.

    Pressing the corner brought the sound back to my Lumia 640 (T-Mo USA). Thank you!

    Glad it worked for you but I doubt its a hardware issue for most with this problem.
    My partner had a 535 which had the same sound issue. It came every few weeks and could be solved by restarting the phone.
    We upgraded to a 640 and I hoped the problem wouldn't surface on this phone but 2 days into using the 640 we have the same issue.
    Googling the problem I can see the sound problem has affected numerous windows phones for a couple of years. They can't all have faulty speakers surely?
    Has anyone found a solution yet?

    did you try blowing out the headphone jack? I haven't heard of it too much on lumias, but some other makers get stuck in "headphones" mode if there is lint in the headphone jack (from pocket carry, etc).

    also - that speaker is lower right if you're looking at the back. Maybe try taking the back off, and pressing in that area to make sure it's contacting the motherboard.
