Unfortunately, I haven't been able to get my second tuner to have
sound.  Following a hint in a newer thread, I ran `cx25840ctl -d
/dev/video0 -l > video0` and `cx25840ctl -d /dev/video1 -l > video1`,
did a diff between the two files, and attached the results.

Scanning toward the bottom of the diff file I see:

-SRC1_MUTE_EN=0 (0x0) "Disable"
-SA_MUTE_EN=0 (0x0) "Disable"
-PAR_MUTE_EN=0 (0x0) "Disable"
-AC97_MUTE_EN=0 (0x0) "Disable"
+SRC1_MUTE_EN=1 (0x1) ""
+SA_MUTE_EN=1 (0x1) ""
+PAR_MUTE_EN=1 (0x1) ""
+AC97_MUTE_EN=1 (0x1) ""

and:

-SRC2_MUTE_EN=0 (0x0) ""
+SRC2_MUTE_EN=1 (0x1) ""

Could it be that the second tuner has the audio muted?  If so, is
there a way to pass an option during module load or post module load
to correct this?
