I just updated to WP 8.1/Denim on Wednesday night. I started noticing this issue on my phone last night. Basically, there is a massive loss of bass when playing any songs.

To let y'all know the amount of bass loss I'm talking about, I'll explain the scenario in my truck. I have two 10's under the back seat of my truck. Currently if I have the bass turned up to 100%, it still doesn't compare to what it used to be at even 50% when it was working fine. If I put it on 50% now, the bass is non-existent.

I've tried many troubleshooting steps to see if I could figure out the problem. I have custom settings on the equalizer that I turned off and the issue still remains. I turned off all the Dolby settings as well and the issue still remained. I also tried playing music through different apps and I still have the same issue.

To make sure it wasn't an issue with my truck, I plugged in my Surface and played the exact same song and compared the two. It was immediately obvious that the issue is with my phone.

Anyone have a clue what could cause this?!?

Just to be sure - did you try a soft reset?

Yes, I manually powered down and also soft reset multiple times.

Check your audio settings on the phone (settings > audio). When I upgraded to Denim, it reset my audio settings back to the default settings. Both the equalizer and enhancement settings.

Edit: I see you've checked them. Are you connecting via Bluetooth, through the headphone jack, or USB?

are you playing via bluetooth or just headphone jack? I use bluetooth in my Mazda and havent noticed any difference.

I had been connecting through the headphone jack. That's how I compared the differences with my phone and Surface.

I just tried connecting through Bluetooth, and the bass worked perfectly. So maybe the headphone jack on my phone is bad?

Have you checked the audio settings that the previous poster said? You have to check with something plugged into the headphone jack to change that outputs settings.

Did you read all of my original post?

I did you didn't mention you were plugged in, just wanted to make sure.

I've had issue with lint in headphone jack. Lol

Haha how did you get the lint out?

An air compressor haha. Canned air might do it too.

I'll try that, but I'm kind of doubtful that's what it is. Other than the loss of bass, the quality is perfect.

Yea i doubt it too, when i had my issue there was a bunch in there and it wouldnt make a full connection so i was only getting mono sound. i doubt it would cause only issues with bass.

I thought I posted in here earlier but it was apparently deleted. My apologies if I offended anyone.

It's not only you because I noticed that with the speakers in my room that the sound is waaayyy lower after the denim update. I don't like it but its bearable. With headphones or through the phone speaker only you wont notice the difference. Only if using external speakers and sets you will see the difference of sound quality and volume before and after the update. It's a noticeable one too.

The only difference I have is the bass quality. My sound quality and volume are still identical.

BOth bass and volume went down for me. Still bothers me today LOL
