Summary0016209: M4A conversion fails non-deterministically (regression 2219)
DescriptionWhen USB syncing with auto-conversion for a set of 5 tracks (all tracks > 212 Kbps --> M4A @ 85%) enabled, some tracks fail to convert:
Bonnie Tyler - Holding out for a Hero and Ed Sheeran - The A Team (they appear to convert but sync as 0Kb tracks)
When performing the same test with WiFi sync, the same two files failed to convert.
(Note also: on other occasions (when auto-syncing larger lists) the Tone Loc - Wild Thing track also generated the missing codec error in MMA.)

When manually converting the 5 files on the playlist, 2 different files failed to convert:
Anna Kendrich - Cups and Avici- Wake me Up converted as 0b files!!
I subsequently tested manual conversion of the same tracks to M4A @40% and it exhibited the same problem.

So it seems that there a bug with M4A conversion that pseudo-randomly results to conversion failures.

See attached logs.

Verified 2223

Tested on 10k of tracks sync 0 fails.

Test Note I have set All tracks > 160 --> M4A @ 85 % to get even more variety of formats to be converted.
