    kinks in the SB2?

    Sean,
    I'm about to buy my wireless set up for SB2 now. Probably FLAC, definitely lossless, via Xandros (Debian based) Linux distro. Any other hardware to stay away from, or more importantly that is really stable?

    Does it keep playing audio? Can you control it from the web interface?

    That shouldn't be. Which receiver?

    Which access point? We tested numerous configs with several dozen
    access points. So far we've had only one issue that I know of, with a
    specific recent hardware rev of the Linksys BEFW11S4 - we're looking
    into it.

    kinks in the SB2?

    Rev 4 of BEFW11S4 is the only one we've heard of a problem with. Rev 2
    of the BEFW11S4 is among the routers in our test suite here and is
    known to work. I think Vidur picked up a rev 4 at Fry's today for
    testing.

    At home I use a Netgear WGT624. The firmware which originally came on
    it was buggy (nothing to do with Squeezebox - the router just randomly
    crashed from time to time). After updating the firmware though, it has
    been running really solidly - I would definitely recommend it.

    The Airports are not bad, but they don't have a web interface which can
    be an awful pain sometimes, and they lack some of the more advanced
    settings. If you need the printer sharing though, they're a good deal.

    SB2 startup glitches

    I got my wireless SB2 today. I had to bring up v6 of the server to use
    it, and after a few glitches it sort of started to work.

    But there are still some glitches. Whenever I play a FLAC or OGG file, I
    hear distorted, 'crunchy-sounding' audio for a few seconds until the
    play buffer fully loads to 100%. Then playback continues normally. The
    problem does *not* occur with MP3 files.

    I'm not totally sure, but it sounds much like the CPU in the SB2 is
    unable to handle a sustained burst of network activity without falling
    behind servicing the DAC. That's just my intuitive guess.

    This is over 802.11g from a WRT54G base station only a few feet away.
    Signal strength is 100. Server software is v6.0.0 trunk; firmware
    version is 8.

    SB2 startup glitches

    Additional comment: the "crunching" during startup does *not* occur with
    the original SB running off the same v6.0.0 server. The problem happens
    only with the SB2, and only when playing FLAC or OGG, not MP3. Haven't
    tried other file types.

    I was surprised to read this as when I connected my new Squeebox 2 to
    first an Apogee Big Ben and then a Genesis Digital Lens
    both locked instantly (the Big Ben in narrow mode) and showed exactly 44.10.

    As I happen to have a Behringer Ultramatch Pro
    (i.e. the MK2 24/96 version of the Ultramatch) lying around
    I just connected my Squeezebox 2 to it and it locks instantly/cleanly ...

    If I recall correctly the Ultramatch MK1 used the old
    CS8402 SPDIF receiver (whereas the MK2 uses the newer 8412/8414 series),
    I wonder which receiver the Rotel RSX1056 uses ...

    I don't think it's a timing / jitter issue. More likely a compatibility
    issue or error in the channel status data or something like that.

    I've been procrastinating upgrading my home receiver to a RSX1056 so I
    can fiddle around with driving its RS232 interface through the
    geekport... I guess this is my excuse.

    I think that also, and the CS84xx receivers interpret the channel status bytes,
    that's why I was wondering whether anything could be deduced from
    the specs/bugs of the CS8402 used in the original Ultramatch
    vs the newer version used in the Ultramatch Pro ...?

    Phil,

    I'm not able to reproduce the problem with FLAC playback on either wired
    or wireless SB2, but I do hear something similar to what you're
    describing when trying to play SlimTris while FLAC is playing. SlimTris
    is triggering a large number of display updates - handling the large
    amount of network traffic seems to effect FLAC playback. I'm still
    trying to track down exactly what's happening on the box.

    Thanks for the report.

    kinks in the SB2? [a little OT: audiophilia]

    My apologies for another post related to the disease of audiophilia
    rather than directly about Slimstuff (soon's my shiny silver SB2 ships,
    I'll get dragged back on topic) but that won't stop me. I haven't heard
    this Rotel, although Rotels through the years have sounded swell and
    this one may sound absolutely fabulous, so this isn't to be interpreted
    as anything negative about the RSX1056, and it'd be swell for you to end
    up having the proper hardware to debug this digital-lock problem,
    but... when I hear of someone shopping for an AVR in that price range,
    I have to recommend giving a listen to the Arcams (AVR-250 and AVR-300)
    before making a final decision.

    I have an AVR-250, and it offers more than a hint of the spooky
    subtle-detail reproduction from digital sources provided by its fancy
    sibling the AV8. There's something about the way current Arcams do
    D/A that I like.

    That having been said, I can report on the downside: my AVR-250
    occasionally (maybe a couple of times a week) gets a little "confused",
    for example after switching from a digital input to the built-in tuner
    no sound comes out, but switching back and forth once more fixes it. I
    never had this problem with a faithful Denon, but the musicality of the
    Arcam totally makes it worth putting up with a few minor quirks, at
    least to me.

    The Arcams can be controlled via an RS-232 port after the fashion of all
    that fancy-pants installer-integrated stuff; is that the RS-232
    functionality you were referring to? The codes are toward the end of
    the manual:

    http://www.arcam.co.uk/downloads/DiV...20handbook.pdf

    Anyhow, sorry for the hijack, and back to your regularly-scheduled
    program. For a hint of the on-topic, my AVR-250 is getting along swell
    fed by an SB1 and we'll see Real Soon (I hope) how it gets on with the
    miracle of the SB2.
