    External DAC problems

    I saw that, too.

    I have de-jittering device and its display starts from around 43.90 and
    steps up slowly to 44.10 where it locks. It takes a while. I remember Sean
    was saying here that it is actually a hardware issue and not easy to be
    fixed by SlimDevice guys or SW developers. He said he would talk with the
    vendors.

    If I may add, not only it takes time to go up to 44.10, but also the
    de-jittering device mentioned above loses lock sometimes and locks back in
    after a few seconds. This means that SB's digital output is not super
    stable or not strong enough? Don't know where this comes from (PS stability
    or ?). I don't remember anyone mentioned that here yet. Sean, would you
    look into this also?

    All,

    I have a wireless SB hooked to an external DAC via the digital optical out.
    The DAC is an MSB LINK III, and it automatically senses an optical signal.

    In normal operation the setup works great. However, when I power down the
    SB, after about 5 minutes, the DAC starts clicking on and off like its
    sensing a signal. I am guessing that the optical out isn't truly off.

    Has anybody else experienced this? I am going to test the digital coax out
    tonite.

    Thanks,

    Michael.

    Slimserver STILL quitting OS X

    I have posted this problem SEVERAL times to this group to little
    or no response. I'm running slimserver 5.3.1 release right now
    but it has been plaguing me since 5.2. After a while slimserver
    just quits. When I go into the preference pane it says "Start Server"
    so I guess it knows it has stopped. I can re-start and sometimes
    it quits again. I have looked into the activity monitor and am not
    super savvy but it seems like this happens when Free memory
    is low and inactive memory is high. perl sometimes spawns multiple
    mDNSResponderPos processes, whatever they are. I have 1.75GB
    of hardwired RAM, one would think that's enough but I also use
    safari and I've heard it has a memory leak. I also have a massive
    number of page outs.

    Anyway does anyone else have this experience running OS X
    (10.3.6) or can make sense of some of what I am saying?

    Please help me, I just want to listen to my music.

    Also, occasionally the music will stop for just a few seconds
    and then start back up. This has notably improved with recent
    nightlies (I try to stay up to date on them) in that it is a single
    pause without static whereas before there were often a clump
    with static.)

    This is a wired squeezebox and I am using Apple Lossless extensively.

    -Harry

    Slimserver STILL quitting OS X

    It just quit again. Can anyone provide me with troubleshooting?
    Would my perl crash log be of help?

    Here it is:

    Thanks!

    Thanks for posting the crash log, Harry. Unfortunately, there's no
    smoking gun there. Usually when SlimServer crashes it's due to an
    error/bug in SlimServer perl code, but not in Perl itself. I hate to
    say it, but the most likely cause for a crash like the ones you logged
    is either a bad installation of Perl (which is part of the OS) or a
    hardware problem (flakey memory, for example).

    I'll ask around, but unless you can reproduce the problem with specific
    actions or data, I'm tempted to blame the computer.

    Slimserver STILL quitting OS X

    This wouldn't be the first time a crash has been traced to bad RAM...

    Anyone know of a good (and free) memory test program for Mac?

    Slimserver STILL quitting OS X

    I think I saw a version of memtest listed on versiontracker earlier tonight.
