Audio stuttering/crackling

[kapa75]

Hi!

I just got my mi5s+ which I love.
But I have a strange issue, whether I'm running a stock MIUI ROM or a AOSP/LOS ROM (Oreo):
When I'm playing any audio, I have some weird stutters/crackling randomly.

It happens both on speaker and bluetooth headphones. It happens on Apple Music/Spotify/Local media. Sometimes it even happens with notifications.

I noticed that it gets worse when I'm downloading a file in my phone or when I'm running a heavy/poorly optimized app like snapchat. I was thinking it maybe it was a bad

I haven't installed any audio mod. Tried various firmware. Kernel settings are on stock. I've tried factory reset, wiping cache

Do you have the same issue? Is there any fix? When I've done some researches I've noticed it's a common problem on xiaomi devices and I haven't found any good fix...
It's such a shame a device that powerful can't play audio properly...

I've personally only had audio stuttering if I have too much running at once. but at that point, the whole phone feels clunky.
and when I say too much, I mean to the point where the phone is hardly usable - everything is delayed.

I also mostly use google play OR the built in MIUI music app. I do have Viper4Android installed, so it could be cleaning up the crackling.
