Glad to hear it.

Setting up lirc can unfortunately be a challenge.

The radio is not (yet) supported for the HVR-1950.  I need to look at 
this again; last time (a long while ago) there was an issue in the tuner 
driver that would have prevented it from working, but by now that might 
be fixed in which case it may just be a simple matter of enabling it 
within the pvrusb2 driver.

Keep in mind that the radio on this device acts differently than you 
might expect for a V4L-driven radio.  The pvrusb2 web site talks about 
this, but in a nutshell the audio stream, like a TV signal, is delivered 
via the V4L device node as mpeg data - with a blank video frame.  There 
are ways to post-process this data into simple PCM audio; that 
information is on the pvrusb2 web site.
