Re "hash value" is a modification flag only which is never changed on MMA side.
A "special rule" I meant some "auto-conversion" rule that you specified. So you have "flac to mp3", but this rule, as you wrote, was specified also during the first sync so this will not be the issue.

So it's very weird that this flag is empty on MMA side during sync. It looks like these files were newly scanned locally and sync info was lost. I was testing it on my devices but never reproduce it.
I will be smarter after analyzing your database.

After your MMA will be updated, please send a log to confirm that your db is included.
Then send your log before and after wifi sync.

Thanks for your patience.

Martin.
Thanks for following up. I'll post the new log id's here. Hopefully I'll be smarter after this too ;)

Hi,
856 build is released as Beta.

I need to analyze your database before and after sync. I am creating new build 1.3.5.856 (will be published soon). This build has increased max limit of database size, so your database should be included in next your logs.

Hi, I have checked your logs.
In all cases, the re-downloaded tracks were auto-converted tracks.
The auto-converted tracks have an additional hash value. If this value is changed then these tracks are re-downloaded.
The issue is that your original tracks hadn't hash value as though these tracks were not auto-converted on first wifi sync.
Unfortunately, your database is too big and is not included in your debug logs, so I can not exactly compare what was changed.

Didn't you change auto-conversion rules between sync?
Do you have some special rule?
Hopefully you can help me answer those questions. What is a "hash value" and what would cause it to change that would result in a re-download? Also what is an example of a "special rule"?

When I initially download songs to to MMA they are converted from flac to mp3 using constant bit rate, joint stereo, high quality. I have not changed any of these settings since the beginning. The only thing I have done with the songs that are re-downloading is play them in MMA.

As I mentioned in an earlier post, the re-downloading seems to happen with some songs that I play in MMA, which had been initially downloaded using an earlier version of MMA. One other observation, it doesn't necessarily re-download all such songs. For example, today I played about 40 songs that had been synced from an earlier version but when I synced tonight only about 30 of those songs re-downloaded.

Please let me know what you think. Thanks.

Still happening with version 0853. Log ID AHF3N4A42.

I think this happens when I play songs that were previously downloaded in earlier MMA versions. For some reason those seem to be the songs that are redownloaded when synced iin a newer version of MMA.

Would be nice to have a substantive response to this on-going issue.

Hi,
unfortunately, your log does not contain info why tracks are re-downloading. Please repeat sync and send me new LOG immediately when sync starts. For sure you can send also several LOGs during sync.
Thanks
The re-downloading is happening again on version 1.3.4.0850. Check for log Q3TZGYVIKG. I sent the log during sync once the downloading began. Hopefully this provides what you need.

Thanks

Thanks, a new version has since come out and I"m not having the re-download problem at the moment. I'll try to send a log during sync next time it happens though.
