Audio on Udemy videos has suddenly stopped working

I’m working through a course on Udemy on my macbook with bluetooth headphones. I’ve no idea why but the audio no longer works. Youtube audio is fine, previous lessons no longer have audio either, restarting browser has no effect. Disconnecting headphones makes no difference. Downloading lecture works, but is hassle.

Solution: In bottom-right, click the cog and change the quality from auto to a fixed quality (eg 1080p). This solved it for me. I don’t know who’s bug it is and I don’t care. I hope this helps someone else πŸ™‚

      1. This worked for me – ‘Pressing up arrow’ on keyboard triggered the sound and also showed a ‘sound speaker icon’ which appeared overlaid on top of the video. This icon did not seem to be related to the video players (bottom right on the video player toolbar) but instead seemed to be a separate sound adjustment. Confusing…

      2. Thank you for this. It fixed the problem I experienced in Safari, since I used my Bluetooth headphones yesterday. Very strange. Was searching for more than half an hour to fix this. Your post solved it!

      3. Excellent. It worked for me . Than you so much. Btw, Can anyone tell why it was not working previously? Thanks in advance

      1. This just happened to me, and I panicked as I was watching the Java course by Tim B. I tried your solution. You are a gem! It worked instantly. Thank you.

  1. Play around with the cog (settings) and volume icon whilst playing a video. I have had the frustrating issue a few times. Took me a while to solve.

  2. when you dont hear any sound from your video courses, when you click the volume icon, there is actually a white upside rectangle – a bar – that will show up. its not very visible because its color blends to the white screen (which is usually the color o the ppts used by the trainors). Color is very very faint pink. so when your sound is 0, that rectangle is fully faint pink.. hardly visible. just click on any part of the rectangle to increase the volume. part of that bar will now have red, indicating increase in volume. and with that, your video will now have sound. hopefully.

    1. This solved my issue thank you ! Had no idea that you had to like ‘grab’ on to that volume bar after hovering on it… geeze, thank you!

    2. Legend! Thank you. Tried the stuff above and it didn’t work. Clearly I had accidentally turned down the volume without realising.

      All sorted now. Cheers Tin!

    3. THANK YOU! This worked for me. What a stupid setup – the number of “waves” drawn on the speaker makes it look full volume, but it has none at all.

    4. Thank you, thank you, thank you!! I have been messing around with this for 2 days. I can’t say much for Udemy response to technical issues. I sent two requests.

    5. i have had the same problem and thought i was going mad but this fix also worked for me – genius thank you

  3. For those who didn’t work, you have 2 option
    1 – Switch the browser
    2 – Click the cog button and click on download lecture

  4. I noticed something odd.
    Once in a while when you start a new video, the udemy volume is suddenly set to zero… Very wierd.

  5. Thanks! You saved me lots of time and hassle. When the problem occurred I quickly found the solution here and fixed it.

  6. Hehe guys, thats a silly reply of solving problems just pressing the up arrow key.I had the same problem and how i solved it is by clicking the unmute audio section that appears on URL section at the right corner of it:)

  7. Hi,

    You are such a genius. Working now. It took a bit of time to get refreshed when changed the video quality.

    Thanks Mate…

  8. Click on the audio button, and a vertical audio regulator bar appears. Drag that bar from top to bottom a little. The audio starts playing!!!

  9. The audio button is in the palette at the bottom right corner of the video along with the quality choose button. the buttons are arranged as follows: audio transcript “CC” Settings FullScreen .
