it also appears that a usb to spdif converter can be used in the event the dac's usb input is limited to 24/96 or lower while the digital inputs are rated higher.ģ. re hdmi, after some more research it appears that an hdmi audio extractor can be used to get digital audio from the computer's hdmi port, which in turn can be fed into an external dac's spdif (coaxial or toslink) input the event the dac does not have a usb input. Yes, pretty much thought that was the case with the headphone jack. hdmi also carries audio, and i think it's a digital signal. If you are using the computer's headphone jack, then it is an analog signal, and has already gone through the dac. when the computer's internal audio processing is bypassed and streamed through the computer's usb port, is that audio signal analog or digital? i'm assuming it's analog, is that right?Ģ. is usb 3.0 backwards compatible with an external dac using a usb 2.0 input? in other words should an external dac with a usb 2.0 input be expected to work fine with audio streamed from a computer's usb 3.0 port?ĥ. also required in order to bypass the computer's internal processing using the usb port, or can the computer be configured to automatically bypass audio processing for all audio, with or without a music player? for example, can the computer be configured in such a manner that it would automatically stream music services such as pandora, spotify, etc., services which don't require music players, unprocessed through the usb port?Ĥ.
is a software music player such as jriver, foobar, etc. is there any way this can also be achieved (bypassing the computer's internal processing) using the computer's headphone jack or hdmi port?ģ. a computer's internal dac (audio processing/conversion) can be bypassed completely by streaming audio through the computer's usb port to an external dac, correct?Ģ. It's just one more thing with wires hanging out on my desk.but I'll live with it.Hoping the forum can help me with following:ġ. That would remove the audio codec from the case, physically and give me more I/O flexibility as well. I'm probably going to go the Proaudio/recording route and get something the like Focusrite that dave_the_nerd has. Then again, there's no guarantee that if I had bought a MB with onboard sound that it wouldn't be noisy. With this NLE rig I bought a server/workstation MB with no onboard sound which in hindsight was a mistake. Same cables, same DVI KVM, same speakers. My new system is based on an Asrock P67 MB.
Over the years I've discovered that some motherboards are just prone to much more EFI/RMI than others.įor example, my old system was based on an Asus P5 Pro MB. My case has no front panel audio (it's a rackmount case), and I've tried using different cables, moving things around, etc. Thanks for the suggestion, Insert_Nickname.
Clicking is MUCH less but the whine is still there.like alternator whine in a car stereo.my tweeters are at ear-level so you can imagine how annoying it is. I just tried moving the Behringer codec away.as far as the cable allows. Quick question for dave_the_nerd With your Focusrite, how do you control the volume of the playback from the computer, since the USB input/output has no associated volume control? Through the mixer/recording software, I'd imagine? I would want to use the Focusrite as a "soundcard" w/o having the mixer software open all the time. I did not try moving the POS Behringer codec (my mixer is solid, BTW ) far away from the PC, though I doubt it'll make a diff.
As opposed to this new Supermicro motherboard which sounds like a frying pan full of bacon, nuts and bolts. Sure, if you put your ear to a tweeter you hear a bit of hiss, but no clicking/popping/whining noises. My main gaming box (Asrock P67 MB) plugs into them through a DVI KVM and it's almost dead-silent. They are KRK Rokit 8's and I've had them for about 5 years now. Thoughts are most welcome as well as any personal experience with USB soundcards. So I'm wondering if an external USB "soundcard" would reduce that noise? Something like this Basic 2-channel output to feed my powered monitors is all I require. It's your typical whining/buzzing/whirring "computer noise." It's darn near impossible for me to concentrate on what I'm doing with all that noise in the background. It's not a ground loop or anything like that. The card picks up a TON of computer noise. It has no onboard sound, but I figured I'd use my old Audigy ZS PCI souncard. I bought a Supermicro MB/Xeon i3 v2.0 to use as the backbone for a new video editing rig.
Some MBs/cards produce a little, some a lot. We all know the inside of a computer case is an RFI/EMI nightmare and sometimes you get extraneous "computer noise" (whines/clicks/buzzes) transmitted through the onboard or PCI soundcard.
