Music very quiet over bluetooth audio since updating to iOS 11

Same problem here. iPhone 6S running on iOS 11.0.3. I noticed that as soon as I receive a notification (and the phone is not set on mute), the volume of the music played on the bluetooth device is increasing on its original maximum volume (like it was on iOS 10, before I had this problem). So is a software problem, definitely an iOS11 issue.

Can you confirm this?

I don't have your certainties.

On my iP7 running iOS 11.0.1 BT's volume (headset or external speaker) shows no significant difference if compared to the one I had with 10.3.3.

But I don't want to be right all the time. You can keep your opinion.

It’s a DECISION because Apple decide to make it that way! An issue is a problem, it ‘may’ be a problem for you which is causing an issue but as Apple created it to work that way it’s a decision! 👍-1F3FB;

It isn’t rocket science! As to your reply of “I’m not helping” I have already answered the post by explaining how Bluetooth volume works when you are connected by Bluetooth to your car only a few posts above yours!

Just because you don’t like the way it works does not make it a software issue! I DO agree though (as I have previously stated) it’s a STUPID setup!

I didn’t ask how it works. I understand how it works, that’s not the problem.

I am repeating myself, I don’t know if this is gonna help me in some way, but at least I hope you’ll understand our problem (mine and richard’s):

As I already stated in my previous reply, the problem appears when I try to play my music on my iPhone 6s (iOS 11.0.3) by any bluetooth device or even through AUX cable (as I newly found yesterday). With the volume maxed out, it is still quieter than it used to be (before I updated to iOS 11). As soon as I receive a notification on my unmuted iPhone, the music volume on the connected device is getting higher instantly like I was used before. And (as I experienced until now) it stays the same until I change the app that plays the music or I receive a phone call. That’s why I know there is an issue and it wasn’t supposed to work like this.

All this is not about how to change the volume on the device, it’s about how loud can it get.

Im sorry, but this is BS. The volume buttons on my Bose BT headphones directly correlate, and turn up the volume on my iPhone7 just as if I was using the buttons on the phone. They are not mutually exclusive. With IOS 11.0.2 and 11.0.3, BT sound is definitely diminished. I can listen to music at full volume which I could never do before. Its as if Apple has decided "Volume Limit" is always enabled at half volume.

I also had this problem. Music was very quiet on bluetooth speakers - almost inaudible unless the phone volume was set at maximum.

I fixed it by simply re-pairing the bluetooth device - go into the bluetooth settings, tap the "i" to the right of the offending bluetooth device, then tap "forget this device." Re-pair the device to the phone and everything should be audible again.

I guess iOS saves some data about each bluetooth device when it's paired, and iOS 11 has a problem interpreting the data stored by iOS 10.

I've got the same issue with my mosconi car system after updating to IOS11. Not always, but very often the volume is so very low that I've to turn the volume of my mosconi system to its maximum. When that happens I set the timer for 1 second, and after the alarm......hocus pocus...... the volume is like it was before the update. I don't understand why. Very annoying!!

I'll try the re-pairing option tomorrow.

I have the same issue on Jabra Evolve 75. Jabra 510 and Bose QC35 headsets. Car is fine.

Notifications set the volume to minimum. When first connected volume is minimum.

iPhone user for 10 years. This is beyond frustrating.

Settings > Bluetooth > device > Forget This Device

And then

Connect one more time ;)

I would try to contact your nearest Apple Store and have an evaluation.
