Hi,
MMA Beta should be out soon almost done with internal tests, which should give much easier WiFi sync experience.

Issues should be simply discovered by scanning QR code on MM5 PC.

At first I thought that it was either because I had analysed volumes in mmw or it was normal behaviour in wifi syncs, but I still get about 75% of my files re-downloading each sync. Any guidance would be appreciated.
Yes it was resolved in my case and I'm using the beta version, although the last update was about year ago now. Would be nice to have an update if only just to be able to wifi sync...

Hi,
Are you using MMA beta? You can apply for MMA beta from ⋮ -> About MediaMonkey.

OK, here are the three logs you requested, please let me know what you think. Thanks

Log ID: B4JQMYJUEL
Description: test ‐ library is in sync

Log ID: PB51FJ1E4Z
Description: test - pre sync log following playing about 40 songs which were previously synced in an earlier version

Log ID: 7C42Q8AYMS
Description: test - post sync. approx 75% of played songs that were prev downloaded in an earlier mma version, re downloaded on this sync.

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.

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.
