ALAC M4A Transcoding Broken
Last modified: 2010-04-19 09:15:29 UTC
Apple Lossless M4A transcoding appears to be broken with these files on several versions of Squeezebox Server and SqueezeOS firmware. Below are the tests performed, with the accompanying server versions, on both Mac and PC. Squeezebox Duet 7.4.1 - Streams 1 second, no audio, then stops Squeezebox Duet 7.4.2 - Streams 1 second, no audio, then stops Squeezebox Duet 7.5.0 - Streams 1 second, no audio, then stops Squeezebox Radio 7.4.1 - Streams 1 second, no audio, then stops Squeezebox Radio 7.4.2 - Streams 1 second, no audio, then stops Squeezebox Radio 7.5.0 - Working The files are located here: http://public.me.com/kpye
I have a similar problem. When I try to playback certain Apple Lossless files on my SB3 the playback seems to start for a second then stops with a "Problem: "can't open file for <file_path>" error. I am using MacOS X 10.6.3 with iTunes 9.1

I think I traced the problem to a parameter size issue ( in my case at least). Here is what I posted in the forum thread (http://forums.slimdevices.com/showthread.php?p=534170#post534170): I did some more testing this morning and I am pretty sure it a path length problem as the album name in the files meta-data is used as a folder name in the iTunes Library (and thus becomes a part of the file path). Even though the problematic files play fine (and MacOS X per se has no size limitations), iTunes itself has problems displaying long file paths correctly in the Info window (see attachment). I then tested it in SBS with a small audio file converted from mp3 to alac using iTunes 9.1 (which was given the same meta data as the "real" 100MB alac file). A mp3 file (which plays natively) with identical meta-data plays just fine and the same file encoded as alac - which is transcoded - does not. It seems thus to me that there ought to be a parameter size restriction during transcoding.

Sorry, forgot to add my platform to the bug report: I am using a Mac Mini as SBS (Intel Core Duo, MacOS X 10.6.3 with iTunes 9.1) which is usually up 24/7. I have both a Radio and a SB3.
Forgot to mark this one fixed.
