I've just tried this. I still get the same issue.
Previous to your last post, i had stream as high and offline as extreme.
This happens both offline and streamed.
When i get time, i'll make a recording of what my phone is producing, so there is more clarity as to what types of crackles i can hear.
My enquiry in the other topic is trying to find a solution. So, i don't know about a particular version. Just one where my current issue isn't present.
Is this on the Wildfire or the Samsung? Is it happening on other players also?
If it's only Spotify doing this I recommend you contact Spotify Support using the form here.You will get an automated reply at first, however if you need to chase them just reply to the email as it does get monitored.
