Why do my speakers sound muffled?

I had the same issue with my Maven pro tablet. It eventually got to the point i could barely hear it even with my ear next to speaker. I initially tried master reset but nothing changed. I removed the back and found that my speaker was a little dusty but had metal shavings beld magnetically all over the front of the speacker. wiped it clean with a soft dry towel and now they work like new again.

"Hi @denese1966 ,

Try connecting headphones to the tablet and check if the audio is also muffled when listening to them.

If the audio in the headphones is OK, try adjusting the speaker balance to see if the problem is with the Left or Right speaker in the tablet. The audio may sound different when doing this but it should be clear and not be muffled.

If the speaker(s) are the problem, here’s the maintenance and service guide for the tablet. Go to p.29 to view the necessary pre-requisite steps and then the procedure to remove / replace the speakers.

The speaker spare part number is 796818-001 but unfortunately when I searched online for the part, there were no results for suppliers. You may have better luck."

I’ve been having the same issue, changing the format seems to work for so long but then it starts again and I have to change it back to what it was originally lol it’s really annoying

The sound coming from my Lenovo E440 sounded muffled. I just reduced the audio quality. Worked like a charm.

"It can be caused by several different things in my experience.

1) A cable issue when using external speakers. Try using a different TRS 1/8"" cable (a stereo patch cable).

2) Some sound cards come equipped with features for 5.1 and 7.1 surround sound. Sometimes after an update, these settings are turned on. If you have a two-speaker system you might be receiving signals not designed to go to those speakers and you hear a muffled sound. The solution is to drill down into your sound card/system settings and ""turn off"" these enhanced setting (ie. Dolby, 5.1, surround sound etc.).

3) The playback/recording frequency is set incorrectly. Try changing the recording frequency to 16 kHz or 24kHz (the two most common) and see if the problem goes away. Sometimes the frequency is just incompatible with your system.

4) Reboot."
