Very helpful. Thanks.

I was talking to some friends from Apple who said that perhaps there is some
issue associated with the latest version of QT which is adding to the
problem. What version of OSX, QT, Lame Encoder and iTunes are you running?

Jason's right - I had been saying transcoding to describe any process
where lame gets added to the data-path to transform the format in some
way... I suppose it's more correctly called decoding when the output is
raw. Sorry.

Anyway - Here's some potentially good news for Tony.

I just installed the Jan 8 build and re-did some of the testing that
had shown problems like tony and others had reported.

Well - with the Jan 8 build - I don't have any of those problems. Since
there's no indication that any changes were made in the code to fix
this - maybe the trick is that I had deleted every single slim file
from my hard disk and did a complete fresh install of the new version.

Maybe its voodoo - or just blind luck, but x-coding with lame is now
working for me (in my case it is truly "transcoding"- since i'm on a
slim).

So the following might be worth trying if you're still frustrated by
these problems.

Here's what I did:

1 - search my local HD for any file (visible or invisible) containing
"slim" - you'll get a list showing prefs files, errorlogs, startup
items etc. installed all over the /Library/... folders.

2 - delete all these files - some will require admin password to trash.
Obviously you can leave anything not related to SlimServer that might
also be in the list - Like all your "Slim Whitman" MP3's.

3 - get the Jan 8 DMG file from the slimdevices website ( I chose jan 8
'cause there wasn't a DMG for Jan 9).

4 - Install it and try your luck.

Craig.

Tony,

I had recently wiped the HD and performed a complete new OS install.
Started with the 10.3 CD - then let SW Update do it's thing.

So I believe its currently at OS 10.3.2 with QT 6.5, iTunes 4.2(72),
Lame is 3.90.

but according to the convert.conf line that Jason H posted earlier...
it looks like lame isn't part of the AAC equation on a Squeeze.

mov aif squeezebox *
$mov123$ $FILE$

These lines indicate that only mov123 is required to go from aac to raw.

I hope my recent success with lame isn't a Red Herring...

Craig.

That's right. The latest nightly builds default to streaming
uncompressed audio decoded from AAC. This means that the fidelity is
perfect and CPU overhead is reduced, but if your network can't sustain
1.5M bits/second, then you'll get dropouts.
