Assuming you are on ethernet (or fast Wifi N), audio quality should be great. There will a slight delay in changing to frequencies, and a large (2 to 5 second) delay in changing the monitored frequency window. These delays are reduced upon reducing the sample (step 4).
To confirm a proper setup and device stability etc, run the following code over SSH:
Resulting in an output similar to:
1 2 3 4 5 6 7 8 9 10 11 12
Obtain devices IP address, either thru;
Now over ssh put the device into listening mode, you can tell the program to only accept connections from a specific ip, or any.
Open Gqrx, goto the Configure I/O Devices prompt.

- SDR instability, is likely due to plugging directly into the raspberry pi. Instead use a POWERED usb hub.
