mourip posted a topic in Music ServersHi, I seem to have developed a new situation in my system whereby when I play DSD files I only get music for about 10 seconds and then it stops with JRMC showing "buffering" while slowly counting up to 100% again. This repeats, never letting the music really play for more than a few seconds. Background. I have a "CAPS" server running Windows 2012, JRMC and Audiophile Optimizer(AO). The caps server has a Paul Pang USB card powered by a +5v external supply. DAC is Wyred4Sound DAC2 DSD SE. JMRC uses the ASIO driver provided by W4S. I recently added a REGEN but the symptoms are there without it. Server runs in CORE mode. Settings in JRMC are as specified by the W4S PDF verified by calling them. I tried removing the REGEN and using a new USB cable but the symptoms are the same. I did have DSD playing fine for a long time and Red Book still plays perfectly and sounds wonderful. My hardware setup for the PC and DAC front end has really not changed. I have however recently upgraded JRMC to version 20 and AO to one of the last beta versions. My only guess is that one of the settings in AO has affected DSD playback. Since I was previously able to play DSD I assume that my CAPS server is up to the task. Before I start tearing down the system to it's frame I thought that I would ask for suggestions regarding a possible cause for the buffering. Thanks! Paul
Hello to all, this is my first post here and it is driven by my curiosity. :-) I'd like to ask owners or testers of this DAC to share their experience with its buffer. I'm not into purchase of it, but according to reviews and manufacturer description it has implemented quite unique long buffer. According to reviews it will take approx. 3 sec to start playback, which translates to cca 0,5MB size with CD format PCM audio, on its max. settings. Usual FIFO length in most designs are about 10ms. For sure FIFO functionality isn't just about its length. If underruns doesn't occur, it is calculated fine. I'm interested in one thing, how is Chords implementation effective? Did you find, that with long buffer setup, QBD sound quality is less involved by incoming data timing? Like variation between different software players and its settings. Does it help to screen different source quality? Best regards Michal
BobAudio posted a topic in Music ServersThis past week I built a Carbon. Thus far I have had no problems playing any files except SACD. Is this a design flaw with the Carbon or simply something I need to change or alter in my Win 8 or MC 18 config? Does anyone have a suggestion that may help my situation? Resource Monitoring on my Carbon NT2800MT running Win 8 32 bit for a variety of files trends as follows: 44.1 kHz at 16 bit => CPU & Max Frequency averaged 15% and 65% respectively 192 kHz at 24 bit => CPU & Max Frequency averaged 17% and 70% respectively 352khz (SACD)* => CPU & Max Frequency averaged 60%-70% & 98% respectively *Note: My Weiss DAC is limited to 192 Khz input. Given that Media Center application must via programming reduce the resolution of the bitstream of the file prior to feeding my DAC. Also note that the 60-70% CPU utilization for the SACD playback is mostly a result of MC18 (40-45%) and System Interrupts (15-20%)
