The sampling part of the funcube dongle is an audio device from the view of
Linux. This means the audio subsystem will 'grab' it and make it available
to applications.

Run (may need to be installed) pavucontrol, go to the Configuration tab,
find the funcube dongle that will show as 'FUNcuble Dongle'
there and switch the 'Profile' to 'Off'.

Now try again with qgrx.

Changes you make with pavucontrol are saved automatically.
