It has always been this easy for about five to eight years for these older 
29xxx devices.  You just likely didn't know the device required external 
firmwares.  You can tell by the dating of the ivtv packages how long those have 
been likely available.

As far as the audio, the PVRUSB2 2900 device is an analog tuner with a 
composite video input, outputing a MPEG stream via /dev/video0 with both audio 
and video.

Merrily echo the proper value into sysfs to switch between composite input, 
analog TV tuner input, or analog FM tuner.

XawTV is for tuning the analog tuner for analog US (NTSC) TV if you're within 
the US.  Likely only good for the remote low power analog stations or tuning 
into amateur radio enthusiasts sporadic transmissions, as almost all stations 
have converted to digital (ATSC) transmissions.

The one really good thing about the PVRUSB2 29xxx devices, is the working 
analog FM tuner.  The FM tuner is included within the analog TV tuner as it's a 
similar frequency.

Going from memory, again echo'ing the proper value into sysfs switches TV, FM, 
or composite inputs.

Have fun.
