To reach this point, you should have just just connected your audio interface and all of your audio gear and instruments, and started the audio setup wizard as explained in this help article

You should now be looking at Step 2 of the audio setup wizard. Click the Audio Input Device list box (pictured below with arrow).

You see the list box open, and you need to examine the list box options until you see the option for "Focusrite USB ASIO - ASIO" (pictured below with arrow). This is the software driver for your Scarlett Solo audio interface. Click this option in the list to select it.

You now see the JamKazam app test your audio interface settings for 5 seconds, and you will see "Test Results" reported on the right side of the screen (pictured below). You should see a reported latency value of approximately 20ms (i.e. 20 milliseconds, which is twenty one-thousandths of a second), which is what the Windows system is reporting back to the JamKazam app. Sometimes this value is fairly accurate, and sometimes less so - more on that in a minute. In any case, 20ms of latency is poor and is displayed in red, but do not fret, as we will make a couple of adjustments to fix this.

First we need to adjust the Focusrite software driver settings. To do this, click the orange ASIO Settings button (pictured below with arrow).

You now see the Focusrite dialog box that controls the Focusrite software driver and audio interface settings for your audio interface. Click the Buffer Size list box, and then select the value "16" for the buffer size (pictured below with arrow). 

Now that you have set the lowest possible buffer size, click the "X" at the upper right corner of the Scarlett dialog box to close it (pictured below with arrow).

Next, please click to open the Frame Size list box (pictured below with arrow) and select the value "1". 

You will likely see the JamKazam app latency test start running again automatically for 5 seconds. If it does not, then click the orange Resync button (pictured below with arrow) to force the latency test to re-run.

The JamKazam app now re-tests your Scarlett 2i2 interface using the new settings you have applied, and your Test Results should now display in green, with a latency of about 7ms. 

Please note that if either the Latency or I/O scores under Test Results are displayed in dark red, this means a test has failed, and the orange Next button in the bottom right corner of the wizard will be disabled. If this happens to you, simply click the orange Resync button (pictured below with arrow) to make the JamKazam test run again. Once in a while, an audio interface test will fail, but if you just run it again, it will often pass.

As an FYI, the Windows system is reporting 7ms, but Windows does not always report audio processing latency with highly reliable accuracy. JamKazam has conducted in-depth scientific/mathematical measurements (using a technique called loopback testing with waveform analysis) and verified that the audio processing latency for your Focusrite Scarlett Solo with these settings is actually 9 milliseconds. 

At this point, we recommend that you verify with your own ears that the audio interface settings you have chosen are working well. To do this, put on the headphones connected to your audio interface and grab your instrument and/or mic. Play your instrument and/or sing - do what you're going to actually do musically - and listen to how the audio sounds in your headphones. You should hear the audio clearly, and it should sound very good/clean. You should not hear any bad audio artifacts - like crackling, snapping, dropouts, or other audio glitches. 

If you can't hear anything at all, you have something set up wrong. First, click the orange Resync button to reset your audio interface. If you still don't hear anything, check that your gain knobs are turned up on your audio inputs. Check that any on/off switches on your microphones or instruments are set to on. Check that your headphone volume knob is turned up. Generally fiddle with all of these kinds of things to make sure everything is connected properly, turned on, and turned up. You can also check that you don't have a microphone or instrument port set to "line" level.

Please note that you may only hear your audio in one headphone, not in stereo in both headphones, at this point in the setup wizard. Don't worry about this. We'll get this sorted out in Step 3 next.

If your audio sounds clean and good, then you are done with Step 2 of the wizard. Please click the orange Next button (pictured below with arrow) to move forward to Step 3 of the wizard, and then click here for the Step 3 help doc instructions.
