iPhone 15 Pro Max sound is really quiet when connected to my cars speakers through USB-C to AUX adapter...

“[…]I updated to 17.1 and have this problem now. I plug my phone in to my whole home system and the volume is very low now. Compared to yesterday where it worked just fine. I have to turn up my system to MAX volume now to be at a listenable level.”

Report this to Apple. See my above reply.

Offering a little solution to this problem.

It doesn’t matter what settings I alter, wether it’s going to “sound & haptics” and turning off “reduce loud audio”

or

going and turning sound check off (this feature does not help people that use Spotify I’d just like to add).

or

forgetting audio device and choosing between the different settings

ANYWAY, HERES THE TRICK TO FIX LOW VOLUME LEVELS.

• Connect your device and begin to play music
• set a 3 second alarm and press your phones off button to go to the Lock Screen.
• when the alarm goes off press “stop”

your music should auto play and you’ll hear the difference in sound instantly.

(If you’d like to test this theory, after doing this trick, go to “sound & haptics” and turn reduce loud audio on then off, you volume should go to half but even when you turn the volume back up it won’t be as loud)

FYI (iPhone 15Pro Max user)

Go to apple music settings and turn off soundcheck

Wrong. You gotta turn off loud audio in the Headphone safety settings. np

Having volume issues with Bluetooth as well. Changed device type, turned off sound check… nothing working.

one thing I found was going to spotifys playback and turning off “enable audio normalization” it instantly bumped the volume a good notch but it’s still annoying that it’s not as loud as past aux with dif iPhone

i have the 15 pro max and with the latest update i used my adapter/aux cord on my radio and before the update i could have my phone calls go through the radio and now they won't. is there a way to fix that?

"As of the writing in February 2022, the Sound Check feature is only available in Apple's stock Music app. This feature doesn't work in other apps, like Spotify"

What cheap adapter did u buy, I got one off temu but was looking for one I could pick up tomorrow, I don’t know if I should get the apple brand or no, my temu one I had blasted like my normal radio and my speakers will have ur ears ringing on normal but this adapter or cord idk which one is making my music quiet even with my phone vol and car vol all the way up I don’t know which one it is adapter or aux cord

Go to the music setting and turn EQ to off is the only solution I’ve found and that only works for the music you have purchased my YouTube music still sucks

Hi,

Idk if you’ve already found a solution to your problem.. i had the same but i figured you just had to turn off the sound check in settings. Hope it helps, it worked for me.

All the best.

This worked. Thanks!
