Topic emu 1212 s/pdif not working
Im trying to record some stuff, so i have a roland vs-840 with a mic atached and im using a radioshack PCM digital audio cable from the rolands digital coax out to the s/pdif in on the card. problem is patchmix is not getting a reading so no sound coming in. this used to work with a red and white mono cable then just suddenly stopped working so i figured it was the cable and replaced it, but still... Please any help would be appreciated

Try to check if the emu and the roland are working at the same sample rate.

should be, used to work and havnt changed anything... but anyways where do i check that?
4
Near the upper right of Patchmix, there is a button with a circle. Clicking on that brings up the session settings window. Set the Emu to External Source and choose spdif. The Emu will then sync to the incoming spdif signal.

still didnt work
6
Do a restore defaults. You might have to reload the session you're using.
7
nope, still nothing
8
What samplerate is the VS set to? The Emu only works at 44.1 and 48 khz. The VS can be set to 32 khz - the Emu will not acknowledge that samplerate.

im not sure, i tried figuring out how to change that, but couldnt find it... any idea?
10
You will find how to change the 840's samplerate from page 7 of this .pdf.
11
thanks, naw still not working
12
Exactly what kind of cable are you using and don't get me wrong, but did you double check your spdif connections?
13
some of these, cept radio shack brand http://www.radioshack.com/product/index.jsp?productId=2049655&cp=&origkw=pcm&kw=pcm&parentPage=search
ya ive had it plugged in different times and nothing

Make sure optical input and output is set to ADAT. Whenever you switch the optical ports to s/pdif, it disables the coax s/pdif.
15
they are and the s/pdif output format is on s/pdif
16
Wait a minute! I was checking the VS-840's specs and it said the 840 uses optical s/pdif, not coax! What coax connection are you using then? If you're using optical fiber to connect the VS to the Emu, then the optical ports have to be set to s/pdif and not ADAT.
17
no, the vs-840 has an optical and a digital, and im using digital to the emu's digital input
18
Then, the only thing I can think of is that you set the recording mode to 32 khz to save on disk space. Like I mentioned before, if it's set to 32 khz, the Emu will not lock to the digital signal unless it's 44.1 or 48 khz. If your project was recorded at 32 khz, there is no other way to change the sample rate once that has been set. You have no other option than to transfer audio via analog. Unfortunately, I cannot find any reference to the VS' screen so I can't begin to tell you where to look. Hopefully, in the Utility menu, there should be some form of info you can access in the project.
19
yeah, i checked that out its in the utility menu and can only be acessed with a disk in. and when i checked it it was on 44.1, plus im not recording on the disk and then playing it back to the computer im just basically using the rolad as an amplifier running the mic through there to strenghthen the mic volume

ok. that clears things a bit. it'd be great if you had a fiber optic cable so you can test the optical I/O. Somehow, I think something's not syncing somewhere. I take it that the VS main outs are mirrored by the s/pdif? The biggest quirk of the Emu's s/pdif implementation is that when you switch the optical ports to s/pdif, you lose the coax digital I/O, so for you to use the coax, the optical ports have to be set to ADAT.

I just remembered something. Do you have the sync card installed? I seem to remember my s/pdif not working properly unless the sync card was connected.
21
yeah, i think i probably will get a fiber optic cable because the setting and hardware seem to be the same as when it used to work, so that seems like it might be... anyways what is the sync card?
22
Didn't your 1212m come with a sync card aside from the 0202 I/O card? Though the Emu should work without the sync card installed, I remember having problems with s/pdif when I took out the sync card. Shouldn't be the case but that's what happened. I just keep the sync card connected to prevent any future problems; doesn't take up a slot anyway.
23
whats it look like and where would it be? because i bought this computer as a used custom built, so i dont know exactly what it should have
24


It's the one on the lower left. It has 2 BNC connectors and 2 1/4" sockets for SMPTE timecode.
25
oh yeah i have that one, the only one that didnt come included was the big external one. also i just got some turntables today and tried to connect them from 2 mono (red, and white) coaxials to one of the 1/4" and also got nothing in patchmix. might have something to do with it...
