DAW can't see guitar input

Postby flipflop » Thu Feb 21, 2019 3:16 pm

g-day all. I recently replaced my hard drive with a CF drive thanks to info from the forum. Thank you again,
NEW problem, I'm using Cubase 9 pro as my DAW and there is no audio communication between the board and my computer.
All MIDI is working and I can record and Bus to any channel, but when i plug in a guitar or mic my DAW can't see anything.
I can hear and see it on the mixer channel strip but the input doesn't seem to make to the DAW.
any ideas?

You're using something like a Motu 2408 to connect your d8b to your PC/DAW?

Sorry for the wait Phil. It required opening the PC. I'm using a RME HDSP 9652

update: I got the channels back with lots of reading and changing of settings. Now I have no media player in windows.
Any suggestion would be appreciated.

Sorry, flipflop, but the media player disappearing, or stopping to work, does not sound like something that's caused by the d8b. The d8b only send digital (or analog) audio, and that in itself, does not mess with applications installed on your computer.

I looked up your card, and it has 3 ADAT ports. So, you likely have ADAT cards in your d8b as well (but you didn't say anything about that, which makes it really hard to guess what your setup is), that you have connected to your RME card.

To get signals to be sent between the two, it's basically a matter of properly configuring the signal flow, and the clock setup (e.g. having the d8b be clock master, and the RME card syncing to the incoming ADAT signal on one of the ADAT ports on the RME card). But I don't know that RME card, so I don't know what the trick for that one is. All these kinds of cards work a little bit differently, so some reading will certainly be required.

Everything else is signal routing on the d8b side, as well as on the RME card side. And that sort of thing DOES usually require some reading and configuring, that nobody else here could do for you, without an intimate understanding of the components in your audio setup, and what your goal is (and you didn't really share much of that, so it's really a guessing game for anyone who read your posts).

The only thing I could imagine that may cause the Media Player to stop outputting audio (but not to disappear, or crash or something), that is indirectly related to your RME/d8b setup, is if the system sounds (i.e. Media Player playback) get routed to your built-in soundcard, but you don't have speakers connected to that. Then you would of course not hear anything.

If you want to send signal from your Media Player to the d8b via the RME card over ADAT, there may be some other factors at play. Since Windows Media Player tends to want to upsample everything to the maximum available sample rate, it's possible that your system would not work right between RME and d8b, if your system sounds get routed to the RME card. It might try to upsample to something like 96kHz, re-clock the RME card to 96 kHz, and then the d8b would not know what to do with those signals, and you wouldn't hear anything (this might have been your first problem, but not sure - there wasn't enough information).

With the right clocking settings (e.g. d8b Master, RME slave), you might be able to force the RME card to operate only in 44.1 (or 48 kHz) and prevent Windows from upsampling and thus keeping the d8b 'compatible'.

But again... all I'm saying above is also very much a shot in the dark, since there weren't enough details about the issue. But again, all the d8b does is output digital and analog audio. So, any settings you had to make for the RME, or on your computer in general should be the cause... nothing specific to the d8b, really.

Sounds like a support call to RME to me.

Good luck!
