ART USB Phono Plus spdif in on Ubuntu [SOLVED]

[steve]

I don't want to send the LINE OUT from the ART to my computer's LINE IN. That would defeat the purpose of having a digital turntable, right?

It would defeat the point of having a nice phono pre-amp.
If you can't get the S/PDIF to work, then analog out from the turntable to the ART and USB from the ART to the computer should give very good results. Whether that is better or worse that S/PDIF from the turntable to the ART depends on how the Analog to Digital Converter (ADC) in the turntable compares with the ADC in the ART.

OK, so I concluded it is NOT an Audacity issue. It is an issue with something else such as my Mobo or the devices. Audacity WILL record from this device if the input to it is analog. The device gets no signal on the digital inputs and so Audacity DOES record what the device sends, and it just happens to be silence. I'll try to figure out how to close this thread, but the final conclusion is:

Audacity works just fine with this ART USB Phono Plus.

I'm guessing the Sound Blaster Extigy USB could be a problem.

Spdif connections can be a bit weird. When manufacturers follow the book, they derive clock from the header. Some devices don't send a complete header, others insert the wrong clock frequency. That's why most devices try to derive clock from the data. The only device I know that uses the header, is the Sony D50 recorder. And that's a real stubborn one.

I've had two different Sound Blaster Extigy USB's here some years ago. Both showed a very badly aligned clock. When combined with other devices that more or less follow the book, they will not sync as they are unable to extract a clock signal because it is too far from the default values.

You could try setting both devices to 48 KHz, 16 bit if possible. That usually works and the clock difference should be minimal. Some spdifs can only do 48 KHz, despite mentioning other possibilities in the manual.

As to the 9VAC: some interfaces need an AC input, because it's easier/cheaper to transform AC. And they need to transform to 48 V phantom power for the mic inputs.

Your ART doesn't have mic inputs, hence no phantom power. Maybe it's just sharing the design with the ART USB mic pre? Or maybe a higher voltage is needed for something else?

An AC adapter should be cheaper/simpler than a DC one. But since they are rare, they can be pricey...

I can't see where to mark this thread as "solved". But it is solved. Audacity sees the USB input and records perfectly well. Although my problem of trying to record from the S/PDIF of the device is not solved, the problem is not with Audacity. So, if someone can show me how to mark this as solved I will mark it.

I have done that for you and locked the thread.

Thanks.
