Jitter is theoretically a potential problem, but one that I believe is rarely actually heard. I have seen elevated noise floor problem with HDMI due to power distribution and ground loop problems and believe that to be a much greater potential.Wayne,
Are you able to identify any differences between audio generated from HDMI or a USB DAC? Either objectively or subjectively?
The frame of reference of this question is that I use JRiver through a Broadwell NUC and Dirac Live. I currently have both HDMI out and USB out of the NUC to an Oppo 105. Have been using the USB for 2CH and HDMI for MCH but this is a bit cumbersome to switch and I wonder if it's worth simplifying.
My hearing tells me there is little difference (none?) but there is alot of chat about jitter, etc.
Thanks for all your tips and reviews.
Hello,I will try to get to it, but have other pressing priorities.:|
It will be at least a few days before I can get to it.
Another little update, concerning use with REW.
My setup is Dirac in the PC/server, and it does not show frequency or channels, only that it is streaming. All is set to 5.1 throughout, with foobar as the player, and the Onkyo AVR always says Multichannel, even with stereo source.Hi, I am using Intel HDMI audio setup to 5.1 (side speakers) in Windows 7 Ultimate, not set as default. I am also using Dirac, setup to 5.1 and default. Dirac Audio Processor will show 2 channels 44.1kHz, while the XMC-1 will still show 5.1, but will show 44.1kHz.
That is what I see in my AVR.When I play stereo using Wasapi Dirac in foobar or Kodi, my XMC-1 shows 5.1!
That is a mystery!When I try mutlichannel, my XMC-1 shows 7.1!?!
Not really, it does not change at all. MUltichannel all the time.Any ideas? Does your Dirac setup automatically change the number of channels properly?
My video/hdmi card is AMD, not sure that makes any difference.PS: When I use Wasapi using Intel HDMI audio (instead of Dirac WASAPI), the number of channels change properly (XMC-1 shows PCM 2.0 for stereo).
Totally agree!This thread was invaluable to me in getting my ASIO and Windows audio configuration working for full 8 channel HDMI support in REW!! I cannot say "thank you" enough!! :TT
A few details of my system's issues are documented here. I would only like to add that AudiocRaver's suspicions about Nvidia cards were correct: some do work. Well, at least mine does. Now! I would also like to add that if you're still at a loss after trying the other tips, make sure that bit depths and sample rates match. Thanks again, Wayne. :clap:
