No Sound: acer cb5-571 chromebook

Fix #1: Clear the cache

Clearing the cache on the chromebook can resolve some audio issues. To clear the cache do this:

1. Click on the chrome setting button in the browser in the top right corner (it looks like three horizontal lines).
2. Click Tools and then Clear browsing Data.
3. Specify that you want to clear information From the beginning of time.
4. Make sure only Empty the Cache is selected.
5. Click Clear Browsing Data.

Turn the chrome book off and then on again and try the sound now. If it still doesn’t work then move onto Fix 6.

Fix #2: Disable all extensions

The sound issues could be the result of a faulty extension. To solve this you need to disable all of them. Check if the sound now works. If it does then the problem was one of those extensions. Now you need to re-enable each extension individually while checking the sound between each enable. Once the sound breaks again you’ve found your culprit.

You can find instruction for disabling extensions here: https://support.google.com/chromebook/answer/2589434?hl=en

(Note: if this doesn’t work then remember to turn on your extensions before moving onto Fix #7).

Fix #3: Browse as guest

Turn off your chromebook and then turn it back on. At the login screen select Browse as Guest. This will allow you to run the chromebook without any special settings that might have been added after the fact. Try to play sound now. If it works there is some broken setting or component in your regular login. To fix this permanently you’ll need to reset your chromebook. Go to Fix 8.

Fix #4: Completely reset your chromebook

This step will completely wipe your chromebook so you need to backup all of your data first. Again: this will erase EVERYTHING and bring your chromebook back to the state it was when you bought it.

1. Click on your account picture in the lower-right corner of your screen.
2. Click on Settings. A window will appear.
3. Click on Show Advanced Settings at the bottom.
4. Find the “Powerwash” label and click Reset.
5. In the window that opens click Restart.
