Gear: I have a MM turntable going into a Furtech alpha 40 phono preamp/ADC. The Amp is a TACT Digital ONLY. and I am using it with my Macbook to play Quobuz and iTunes (from hard drive).
The furtech is said to be an a to d converter, and I also have a freestanding HRT Linestreamer a to d converter.
They are showing up on my MAC Sound preferences both input and output. I also have downloaded Audacity.
Here is the problem: no sound from my turntable. My computer input is detecting the signal.
What am I doing wrong?

It's hard to pinpoint your exact problem, but here are two suggestions:
1. What's your System Preferences/Sound - Output set to? If I'm doing A to D conversion, then I usually set the output to Internal Speakers.
2. I don't use Audacity, but is there a "play though" option there that needs to be set?
One other thing... make sure your Audio MIDI Setup for your input device is set to the bit rate and sample rate that you want to use.
I have recorded with Audacity and I did need to make some settings in it at runtime to be able to record. I was using windoz not Mac though.Anyway here is a screen shot of the setting I need to do when recording in windoz with Audacity. I have to choose the input and output devices:
I will add that I decided to do all my digitizing of my vinyl without having PC in the loop. I am using either a Korg MR-1 or a Sony digital recorder. The Korg recording to DSD sounds sweeter to my ears. I have been very pleasantly surprised how good most of the digitized to DSD LPs sound! I did buy a new AT moving coil cartridge and relegated the Grado MM cartridge to history...

Simplify:It's a bit confusing to me because the Alpha Design Labs ADL FURUTECH GT40a will operate as a phono preamp, DAC, or ADC over its USB port but I'm not sure how that is configured.
SETUP 1:
- Do not use the TACT at all.
- Use the GT40a strictly as a phono preamp. Connect TT to the GT40a phono inputs. Do not use it's USB port at all.
- Connect the GT40a phono outputs to the HRT LineStreamer RCA inputs.
- Connect HRT LineStreamer USB to the Mac.
- Plug headphones into the Mac to monitor audio. Or plug headphones into the GT40a jack to monitor audio.
Use Audio MIDI setup on the Mac and look for the HRT LineStreamer. Choose it as the audio output device. Look at the settings in Audacity to ensure it is getting its signal from USB/HRT LineStreamer. I haven't played with Audacity in several years so I can't be more specific.
Launch Audacity. Hit record. Play a record. Adjust GT40a volume output. Adjust Audacity volume level.
Do you see signal activity in Audacity on your Mac screen as the record plays?
Can you adjust Volume on your Mac in order to monitor the audio via headphones?
NOTE: If this setup works, the nice thing about the GT40a (as with my PS Audio GCPH phono) is that it has a Volume output level control. The trick is to set the Volume level output from the GT40a to be provide a sufficient and strong enough signal for good dynamics w/o over driving or excessive clipping of the digital signal into Audacity. You can watch the VU meters in Audacity.
SETUP 2:
Not there yet but here you will try the GT40a alone w/o the HRT Linestreamer. One advantage here if you can get this setup to work is that the GT40a has a headphone output for listening while recording.

Don I have to record? I'd be happy just to play a record.
