  1. there is no channel 0 in Apple's Audio Midi Setup, here's what I have configured now: This mapping is correct, as I can verify easily by clicking on the speakers and playing a test tone. What is irritating me, is that the surround sound is still odd, when I am playing ripped SACDs (DSF) from JRiver: Most of the vocals are coming from the left rear speaker - it almost sounds like a second center. Swapping channel 3 and channel 5 does not help. That's why I was in doubt if my channel mapping is wrong or if there is something misconfigured in JRiver. However now, I rather suppose the tracks were not ripped accurately. I used Ted's script with the --mch-tracks and --output dsf option and all surround recordings sound somehow spatially displaced when I am playing them in JRiver on my Mac with the exaSound e38 DAC (while the original SACDs sound great in surround with the same Amp + Speakers) If the files were ripped incorrectly, this would of course also explain the occasional dropouts. My JRiver benchmarks look like this: === Running Benchmarks (please do not interrupt) === Running 'Math' benchmark... Single-threaded integer math... 4.366 seconds Single-threaded floating point math... 2.406 seconds Multi-threaded integer math... 2.218 seconds Multi-threaded mixed math... 1.196 seconds Score: 1865 Running 'Image' benchmark...

If it doesn't get better on Windows, can we compare the file sizes and checksums of some of our DSF files? What music do you have? My SACD collection is mostly Pop/Rock (Pink Floyd, Depeche Mode, Kraftwerk, David Bowie, Dire Straits, Peter Gabriel etc.)
  2. Is anybody else playing the multi-channel files? I have just configured JRiver (on a Mac) for use with an exaSound e38 DAC (according to the instructions on the exaSound Web site) and I have some difficulties with playing 5.1 channel DSFs. 1) Occasionally, I have audio dropouts, even for DSF-sources from the local harddisk (i.e. it's not a network latency problem). Should I fine-tune the JRiver buffering somehow? 2) I am also not sure, if I did the channel-to-speaker mapping correctly in the Audio Midi Setup, on the Mac. Of course, channel 1 is the left front speaker and channel 2 is the right front speaker - but what are the correct channel numbers for the center, the rear speakers and the subwoofer?
  3. Can someone confirm that the multichannel version of Kraftwerk's Autobahn (from the Minimum Maximum SACD) has an audible dropout around 07:20 (not present in the stereo version)
  4. Does anybody use the Manhattan 2 with MPD on Linux? I had a Stereo 192 before and I was using it with lintweaker's ALSA driver Now, I have the Manhattan 2 which should work driverless with Linux. Actually, the device is recognized and listed as card 1, when I type aplay -l Therefore, I configured device "hw:1,0" for the audio_output in my mpd.conf But when I try to play something, MPD complains: "Device or resource busy" I can play files manually using the Manhattan (by typing aplay <file>.wav in the terminal), but this is of course not the way, I want to use this DAC - It should be connected to my Server running MPD and I want to use graphical clients (on Android/iOS) for remote control (just like I was using my Stereo 192 before). When I write aplay -D "hw:1,0" (like configured for my MPD), I get this error: Sample format non available Available formats: - S32_LE - SPECIAL Can anybody help?
  5. .. any news about Linux compatibility? In an interview from 2014, exasound announced "Linux drivers to be available in the very near future"
  6. Cambridge Audio BD752 should also be on the list (I copied all my SACDs to my NAS with the player - with the latest firmware installed).
  7. Ripping SHM-SACDs also works perfectly. I just copied The Velvet Underground & Nico to my NAS. In the Cambridge Player (BD752) Setup, I had to disable "Auto Power Off" because the ripping process takes more than 20 min and the player does not seem to be aware of any actions while the SACD is read.
  8. if it is an HDMI grabber (like the Blackmagic devices) you can use the Media Express Software on your Mac to display video from your Oppo BD Player on the laptop screen (but you need to select the same video format for input and output). So, this is actually an option for ripping SACDs from your Oppo without buying any new hardware.
  9. Cambridge as well: My 752BD not not visible in the network before it did an HDMI handshake (with a monitor, TV or AVR). Thus, powering it on with the stick plugged in is not enough: I have to power on my AV Receiver initially. Then, I can ping the player's IP address and start ripping.
  10. HQPlayer requires Roon for an iOS-Remote, doesn't it? Have you tried, if multi-channel DSD works with MPD on the e28? (MPD is free)
  11. what software do you run on that server? mpd? lms? roon? jriver?
  12. .. do you use your Oppo/Pioneer player to listen to the music? Doesn't it convert the DSD data to PCM before playing it? I did - they are still waiting for the release of the HDMI 2.0b specification before they will start producing the new DACs. Thus, currently the Evolve II is not available at all. The HDACC II will support native DSD over HDMI, but only 2ch. What other solutions for multi-channel playback of the extracted DSF files are known? I've seen the exaSound28 but there seems to be an unresolved issue with DSD DoP: http://bugs.musicpd.org/view.php?id=4272
  13. I am using MPD on Linux and I configured an ALSA output (using USB-2) to play the 2ch DSF-files via my Mytek Stereo 192 DSD DAC. Does anybody use the multi-channel files? I am thinking about ordering an Essance Evolve II from essenceelectrostatic.com to play the the multi-channel files via HDMI 2.0. Do you think, this will work?
  14. for me it works perfectly fine. Thanks Ted! I am using a Cambridge Audio Azur 752BD and I do not even need to wait for the player to boot: Here's what I'm doing: 1) I just power on the player with the stick connected and the tray opens. 2) Then I insert an SACD and close the tray (no ABCD is scrolling in the display, everything appears to be normal, i.e. the SACD is recognized, starts playing and I press stop) 3) I run sacd_extract -i <Player-IP> -I -P from a Linux laptop in the same network and it starts writing a copy of the disc contents into a local .iso file Once I am done, I can immediately insert the next SACD and start ripping again (by repeating step 3) I was not able to get root access (ssh -l root) to the player, however, this isn't necessary
  15. Hi, after 4 months, I'm back with an update: I finally solved the problems mentioned above (glitches, dropouts etc.) by buying new hardware: I replaced my (really) old HP Laptop with a Lenovo IdeaPad Yoga 11S (the 3rd generation i7 version with 2,6GHz, 8 GB RAM and 256 SSD), reinstalled Fedora (Release 20 "Heisenbug") + MPD 018. Now, I can play all my high resolution audio sources (FLAC 192, DSD etc.) without any interference via my Mytek DAC and use MPoD on my iPhone for selecting the tracks I want to play. The problems were just caused by my old laptop (too little memory and processing power). I can highly recommend the Yoga 11S + Fedora as a music server: I am using it in the "stand" mode (with the keyboard upside down) on a DJ laptop stand (with the Mytek DAC on the middle shelf). This way, it does not look like a laptop but rather like some sophisticated HiFi gadget (especially with the small-sized 11-inch display). The touchscreen worked out-of-the box on Fedora (in contrast to WiFi, but I prefer to connect my NAS via ethernet anyway: therefore, I plugged in an ethernet adapter which also did not require any additional driver installation). With the SSD drive, the laptop boots up super fast, is extremely quiet and (even together with the Mytek and high-end USB/Ethernat cables) the price was less than that of most of the "reference" Music Servers (Lumin, Aurender, Antipode, ...) To get back to the topic: After my experiences, I agree with (most of) you about that Linux is a great platform for music playback in audiophile quality. It is exactly the same as what you get when you buy one of the "reference" boxes, with the advantage that you can choose your own DAC (listen to some and pick the one you like the most). The only disadvantage is that you have to configure it yourself and the setup still requires some work, as described in my previous posts (but for my new laptop, I neither had to adjust audio_buffer_size and buffer_before_play parameters in mpd.conf nor the "nice level" of MPD to get stable playback). However, I disagree with (some of) you about that you need a special Linux distribution for this purpose, like AP-Linux, Daphile or preferably one that has no graphical environment at all (like Voyage). With my 2,6GHz i7 processor, high resolution music rendering works (up to DSD128) without any audible difference when a graphical client (i am using GMPC) is running on the same computer at the same time (not even Fedora's screensavers can disturb MPD). However, GMPC offers another interface to the server which is a nice alternative to the iPhone since the touchscreen can be used for browsing the music library and it displays cover art, lyrics etc. which looks pretty cool (as do the screensavers). I am still using a minimal desktop manager (XFCE) and GMPC is running in full-screen mode, most of the time. Another advantage of Fedora (over a headless Linux) is that I can run other media playback software than MPD on the same laptop: I run, e.g., XBMC for streaming movies from my NAS to my TV and Mopidy to stream music from Spotify (using my standard MPD clients for remote control) and Rhythmbox for Internet Radio. Although everything sounds and looks so great, there is still room for improvement: At the moment, I am looking for a better (seamless) integration of MPD with Spotify and Internet Radio. Currently, I still have to decide whether I want to listen to something from my own collection on MPD or to a remote source (like Spotify content or Internet Radio). I'ld like to have one server application on Linux that can access any music source. My idea is, that I get inspired by Internet Radio, what to stream from Spotify and after pre-listening on Spotify, I buy the releases I like in high resolution formats like FLAC or DSD (from HighResAudio, HDTracks etc.). That's what I am already doing, but I still have to use multiple programs. One solution to that "problem" would probably be Independify which I could install to access Spotify and install the UPnP Plugin to access Indipendify from MPD. Scripts for accessing Internet radio stations from MPD are also available. But this looks all pretty complicated. Has anybody of you ever set up such a playback infrastructure on Linux? I've also seen that MPD 018 already includes Despotify support (i.e. I successfully compiled MPD018 with the --enable-despotify option). As far as I know, Despotify is a command line client for Spotify (which I never used) and I could not find a lot of usefull information about it. Does anybody know how Despotify can be configured to access Spotify from MPD?
