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

did that, volume is still the SAME

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.

Go to apple music settings and turn off soundcheck

This worked. Thanks!

This worked! Thanks.

If you’re using Apple Music go to the settings for Apple Music and turn sound check off.

Same problem for me. Just tested with my iphone XS and the 15 is MUCH lower... I'm using the apple adapter. Doesn't matter the app

THANK YOU!! This is the comment guys I turned it off and it automatically fixed itself. Was driving me crazy lol
