Jriver media center 21 bitstreaming6/30/2023 ![]() ![]() Unfortunately, the vast majority of Classical multichannel SACD releases are in 5.0, not 5.1. Asking MC to convert DSD to PCM fixes the channel layout. With DSD Bitstreaming, of course, DSP Studio operations are bypassed and the output from a 5 channel file, regardless of output settings, results in the SL going to the subwoofer, SR going to the SL and the SR speaker being silent. With PCM and specifying "5.1 channels" in output, MC successfully remaps the channels by inserting a silent channel 3. If there are only 5 channels, i.e., there is no LFE signal on channel 3 of a 6 (5.1) channel. If there are 6 channels, all's well in PCM and in DSD-DoP. It turns out that, despite the multitude of options and variables, the critical factor is the number of channels on the recording. I have resolved this issue with the help of Jim Hillegass and miniDSP's Tony Rouget. Test each component in the audio path outside MC, and see if you can locate the issue. Has it worked before? Can you downgrade the miniDSP U-DIO8 firmware/driver to see if an earlier version works? If that doesn't work, tell MC to output the top two channels to channels 7 & 8, and connect your third DAC to the brown cable. If there is a mix up in the cable, maybe the output you want is on the cable for channels 7 & 8? Try connecting the DAC for channels 5 & 6 to the brown cable for 7 & 8. Are you sure channels 5 & 6 are set to full volume? Linking only links each stereo pair, not all channels. You have said the miniDSP U-DIO8 volume settings are locked and linked. Or maybe there is a problem with the supplied miniDSP U-DIO8 cable. ![]() So it sounds like either the ASIO driver or the miniDSP U-DIO8, both of which are outside MC, is applying some volume adjustment to the audio for channels 5 & 6, thereby corrupting the DSD stream. So whatever is happening, is happening outside MC, and is being done to channels 5 & 6, regardless of which DACs are connected to those channels. ![]() Many DACs suffer from pops/clicks or gaps in playback when switching to/from DSD mode, rather than remaining in PCM mode. Some DACs do a bad job of this, while Media Center does a good job of it. It also means that you are reliant on the DAC's filter to cut out all the junk high frequency noise present in the DSD signal. You cannot use Media Center's volume control, features like volume leveling, room correction, speaker calibration, or any other DSP you may wish to apply to playback. You arguably don't even need a sample rate that high when converting DSD to PCM, and 24-bit 48kHz would be more than enough.īit-streaming bypasses all DSP inside of Media Center. Though converting from 1x DSD to say a 24-bit 96kHz PCM track is not a reversible process, you are not losing anything by doing so - only filtering out noise that was added by the 1-bit encoding, and what is being filtered out is beyond the human range of hearing.
