  1. After spending time looking at a couple of renderers I decided to checkout Audiophile UPnP Renderer again. I had moved my dedicated W10 audio PC and was using an HDMI cable to an LG TV for my monitor. I discovered that the LG TV shows up as an audio device, connected via HDMI. I brought up Audiophile UPnP Renderer, but it would not play through the Windows default USB sound driver. This is the same USB driver and configuration that plays great through my Benchmark DAC1 USB when I use Amazon Music or Media Monkey locally, and the Tunebrowser renderer for UPnP. Just to see what would happen I went to Audiophile UPnP Renderer's audio device selector and switched the audio to the LG TV and it worked! It worked using the local drag-n-drop mode (debug) and also when playing from my NAS using BubbleUp UPnP as my control point. So, Audiophile UPnP Renderer can play audio through my TV but not through the default W10 USB driver (USB audio mode 1). It's not the USB audio driver, or the Benchmark DAC1, because they work fine with multiple other music applications. But it is also not the Audiophile UPnP Renderer installation or configuration, because it works both in local debug mode and in UPnP Renderer mode when used with the LG TV. So a logical conclusion is that there is some unique incompatibility between the Benchmark USB driver interface and the Audiophile UPnP Renderer's USB driver interface that is preventing their connection. Of course I have learned that logic is a poor substitute for information when trying to troubleshoot problems like this one. I am hoping that someone here just might have a Benchmark DAC1 and Audiophile UPnP Renderer with Windows 10 and managed to get them to play nice together. I'll also contact Benchmark Support just in case they may know something. (Note that my postings above explain my hardware configuration in more detail, so I didn't repeat it here.) -john
  2. Well, I'm back only this time with a straight forward question. Does anybody have Audiophile UPnP Renderer running successfully on a Windows 10 machine? -john
  3. Thanks to DuckToller and Solstice380 for helping me out. I saw replies by valer_valer on this forum in another thread from as recently last year, l was hoping he was still around. I also thought that Audiophile UPnP Renderer was more well known. Still, it was bad form to use the abbreviation without defining it at least once, so my apologies for that. I got a suggestion to look into the OpenHome renderer from over on the MinimServer forum which I hope to do in the next day or so. Happy listening, -john
  4. AR has many positive posts, and I believe it is exactly what its name implies, but l cannot get it to play a track. My PC is a new build with Windows 10 Home, i3-8100 CPU, 32GB DDR4, 1TB M.2 PCIe NVMe for the boot drive. My library is provided by MinimServer 2 on a Synology NAS. My audio device is a Benchmark DAC1 USB, which uses the standard Windows USB 2.0 driver, it is configured for exclusive control with 24/96 playback and all enhancements disabled. I played maany 16/44.1 and 24/96 files locally on the PC with no issues using both Media Monkey and Amazon Music. My goal was to validate the digital and analog audio connections and audio path, not necessarily achieve bit-perfect playback. Next, I installed AR v2.3 along with MSVCP x86 2015 Redistributable on my new Windows 10 machine. The AR window comes up, and AR shows up as a renderer in BubbleUPnP on my Android tablet. But when l select a track to play the track name appears in the AR window on the PC, the album artwork appears in the AR window on the PC. But all that happens is BubbleUPnP displays the error message. "Action failed (Code: 501)" which equates to "I can't do that" from the renderer. So, there must be some communication between MinimServer and AR. Having read on another thread that AR had a "back-door" drag-n-drop debug capability l tried to use it locally to get a response from AR, but even though the cursor icon showed a file drop onto the AR window was allowed absolutely nothing happened, the track name didn't even display. This was an indication that the problem was isolated to AR. So, as a test l installed TuneBrowser as a renderer, enabled open home, and Windows security wanted admin permission to open the network connection. TuneBrowser played many tracks successfully with MinimServer on the NAS as the library. I uninstalled TB, switched back to AR but its behavior was exactly the same as before. I am certain there is some AR set-up or other configuration that l am missing. Does AR have a settings page, or is there a Windows/network configuration setting that I have not found? Are there network ports to map, or permissions needed? Is it a WASAPI issue? I'm not ready to accept that it is this difficult to get AR working, I must be doing something wrong.
  5. Thank you for your reply and suggestion, you are right that l should have included that information as well. The audio device is a Benchmark DAC1 USB. I have it configured under Sound Control for the exclusive mode and also 24-bit/96KHz playback. I have been using it successfully for several weeks with local players (e.g., Media Monkey, Amazon Music Ultra-HD) to check out the cabling, DAC1, and analog components. Now l have added the NAS for my music library, and I'm working on getting UPnP configured. Because this is the same audio playback device l used successfully for TuneBrowser l had ruled it out as a problem because it was working with other software. However, one thing l have learned about software (and hardware) is that when you don't find the problem where you think it is, you will probably find it where you know it isn't. So, l will examine the complete path again, and post any significant results. Thanks again! -john
  6. More detailed information: I have MinimServer 2 installed and running successfully as my UPnP server on a Synology NAS. I have a small library of tracks. I have BubbleUPnP installed on my Android phone. I downloaded Audiophile UPnP Renderer v2.3 (AR) and the Microsoft Visual C++ 2015 Redistributable. I started AR successfully on a recent build with Windows 10 (Home) intended to be a dedicated audio player. I was able select AR as the renderer in BubbleUPnP, and MinimServer as my Library. I selected a track and hit 'play', the track name showed up on AR's display but l received the message "Action failed (code: 501)" from BubbleUPnP but no audio. Futrher investigation revealed that is a generic error that is sent from a renderer to a control point when it cannot perform the requested action. Another renderer option in BubbleUPnP's list was the Chromecast attached to my TV. So l chose the Chromecast as the renderer and the selected track played through my TV (an interesting result but not quite the one I was hoping to achieve). Next l downloaded and installed "TuneBrowser". I had to enable "Open Home" in TB's network settings and tell Win10 to allow the network connection, but once l did that and changed my BubbleUPnP renderer selection from AR to TB I successfully played about a dozen tracks. I know AR works, and I really want to get it working for me. I suspect that something has to be configured or enabled, but l have no idea what it is or how to do it. Any assistance, or suggestions, will be most appreciated.
  7. I downloaded the Microsoft Visual C++ 2015 Redistributable and that resolved the missing .dll files problem. Now BubbleUPnP is giving me the "Action Failed 501" error when l try to play a track through AR. AR does show the track name, so they are communicating. But, l have no idea what "Action Failed 501" means. I've read on other forums that the error can happen with other renderers, even hardware renderers.
  8. I just downloaded Audiophile UPnP Renderer to a new Windows 10 install (Home Edition). I too encountered the "msvcp140.dll is missing" error when I tried to run AR. I didn't see a clear-cut solution in this thread, but the latest entry is over a year old. I am hoping that by now this problem has a known solution, which is documented as a reproducible procedure somewhere. If so, can someone please point me in the right direction? I built a dedicated audio player in a mini-ITX box, and now l am in search of a high quality UPnP renderer (player). I had hoped l found one with AR.
  9. I don't see anything in your article about a video card, but the P5Q-EM has on-board video support so I presume that is what you used. The Zalman TNN 300 seems to want a video card installed in the slot immediately next to the CPU (like the old AGP configuration) so the supplied heat sink plate and pipes may be used, but they do not appear to even fit the newer PCIe video cards. How is the heat from the on-board video dissipated? …or is that a problem? The open case photo in your article appears to have a video card installed, but because the mobo pictured isn’t a P5Q-EM I’m guessing it is a Zalman stock photo; however it is a mirror image reversal of the picture on the Zalman website (that had me confused for a while). Also the next to last picture shows the optional audio amp mentioned in the TNN 300 manual, which could be confusing to your readers (it confused me until I read the manual). Why not use pictures of your build? <br /> <br /> The TNN 300 manual, page 22, first shows a diagram of “Region B” and states if “the FETs near the CPU are located in region B, the RTB1’s (Rear-mount Thermal Blocks) cannot be installed.” But then at the bottom of page 22 another diagram identifies the exact same area as the “FET area” with the RTB1s installed, so the manual completely contradicts itself, on the same page! ...so who know which is right? Did you have any issues installing the RTB1s beneath the FETs near the CPU on the P5Q-EM? <br /> <br /> On another topic, you mention that you managed to disable all but four services from starting upon the OS boot-up. Can you share with your readers which four services those were? …or perhaps list the five or six that involve some trial and error to disable? <br /> <br /> I have been looking at the ASUS P5N7A-VM mobo. It seems to be very similar to the P5Q-EM, except it has one less PCIe slot in favor of another PCI slot, and it uses an NVIDIA GeForce 9300/nForce 730i Chipset which is described as a combination of the northbridge and video functions in a single chip with a very hefty fanless heatsink installed. The layout is so similar to the P5Q-EM that I expect it to meet the criteria for mounting in the TNN 300 case. <br /> <br /> If you know of a retailer who still has the TNN 300’s in stock at a good price, could you let your readers know?<br />
  10. Being somewhat familiar with digital data and controls I have always wondered why there was so much press given to the jitter specs of digital transmission devices and protocols. It seems to me that a small bank of dual-ported RAM designed as a FIFO buffer could be used to write the incoming digital data stream, using the transmitting clock for synchronization. Then the data could be read from the FIFO and clocked into the DAC using a very accurate local clock. I believe this would completely eliminate jitter introduced by the digital transmission, leaving only the jitter associated with the local clock, which should not be difficult to minimize below a measurable threshold considered to be acceptable. (Of course any jitter introduced during the sampling of the original audio signal would always be present, but no DAC can overcome that.) Given the cost of medium to high end DACs, I can't imagine that the cost of such a RAM FIFO and local clock would add that much. Perhaps I have oversimplified and overlooked a significant technical issue, can anyone here explain why this approach wouldn't work, or isn't widely used?
