Julian Alden-Salter [EMAIL PROTECTED] writes: When I was setting up my squeezebox2 I had to remove my behringer ultramatch (mk1) from between the sb2 and my dac. With the ultramatch (a jitter buster amongst other things) in the loop I got no sound and the emphasis light on both the dac and the behringer flashed randomly. 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 ...

Re: [slim] kinks in the SB2?
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. :) ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

RE: [slim] kinks in the SB2?
First, mine goes blank for no apparent reason sometimes. Blank screen. Some new information suggests that this might be triggered when the server is stopped and then restarted (ie something to do with the reconnection logic on the client). Does that jibe? _ More like when I go through the connection process--like right after it gets a DHCP IP address.

I guess this is my excuse. :) 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/DiVA%20AVR250%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. ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Phillip Kerman wrote: First, mine goes blank for no apparent reason sometimes. Blank screen. I see that too. I don't think the unit actually crashes, but it can be disconcerting. Also, I'm trying to compare the digital out into my DAC to the internal DAC but the digital out can't stay locked (I think that's it... my receiver keeps reseting like it used to between PCM and MP3). I wonder if this is could be related to the crunchy distortion I reported last night with my own SB2. I can't confirm it, but it very definitely sounds like the firmware in the box is starving the DAC when it has to handle the sustained, high speed burst of incoming traffic that fills up the playback buffer with raw PCM data. If the DAC is indeed being intermittently starved, perhaps this is killing the clock on the S/P-DIF output and making it difficult for your external DAC to maintain lock. Does the problem happen on all files, or only those transcoded to raw, high speed PCM? And does it persist through the entire track, or does it only happen at the beginning? The crunchy distortion I notice on my SB2 only occurs on raw, high speed PCM, and only until the buffer fills. When that happens and the server backs off to its maintenance speed of about 1.4 megabits/sec, the distortion goes away. It just occurred to me that I could try forcing the Ethernet down to 10 megabits/sec and see if the problem still occurs. If it's indeed due to DAC starvation from lack of proper CPU real-time management, this might work around the problem by limiting the peak speed of the buffer-fill burst to only 10 Mb/s. --Phil ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
Re: [slim] kinks in the SB2?
First, mine goes blank for no apparent reason sometimes. Blank screen. Does it keep playing audio? Can you control it from the web interface? Also, I'm trying to compare the digital out into my DAC to the internal DAC but the digital out can't stay locked (I think that's it... my receiver keeps reseting like it used to between PCM and MP3). That shouldn't be. Which receiver? Plus, it won't connect to my wireless network--though the tech support seems to think it's my access point. 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. ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

RE: [slim] 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?

Re: [slim] kinks in the SB2?
I'll test it out more... basically, it's dead then I unplug and try again. I'm trying to identify if it's a software issue or a display issue. If the former, you'd probably not be able to ping it. If the latter, audio would probably keep playing. At any rate this is a new one but we'll figure it out. ouldn't be. Which receiver? Rotel RSX1056.

At the time we shipped there were no known serious bugs (s/pdif and wireless issues are always serious, btw). However, given the literally millions of permutations of access points, operating systems, and stereo systems etc in the world, some new bugs are bound to pop up. We'll work as quickly as possible to nail them. ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
