I recently purchased a brand new Hauppauge WinTV/Radio and after
struggling a bit with some hardware problems (probably an IRQ
conflict) it now works fairly well.
However, I'm having a few audio related problems:
* I get no audio in FM radio mode. I've tried a gazillion different
radio tuner applications, including "radio" from the xawtv
package, and all they produce is complete silence. The mixer on
my sound card *is* set correctly and the audio cable *is*
connected, since I get audio when tuned to a TV station (see
below). I also provide the "radio=1" option to the bttv module.
When tuning to a radio station, this debug output is produced from
the kernel driver:
,----
| msp34xx: setvolume: 0:0 0x00 0x00
| tuner: radio freq set to 400.00
| tuner: PLL not locked
| tuner: Signal: 16384
| msp34xx: setbass: 32768 0x00
| msp34xx: settreble: 32768 0x00
| msp34xx: setvolume: 65535:65535 0x73 0x00
| msp34xx: setvolume: 65535:65535 0x73 0x00
| msp34xx: setbass: 32768 0x00
| msp34xx: settreble: 32768 0x00
| msp3400: FM setstereo: 1
| msp34xx: setvolume: 0:0 0x00 0x00
| tuner: radio freq set to 92.62
| tuner: PLL not locked
| tuner: Signal: 24576
`----
I'm guessing the "setvolume 0:0" is the problem here. Changing
mixer settings through the tvmixer module has no effect, and
exiting the radio application and using "v4lctl volume" has no
effect, either.
* When tuned to a TV station in xawtv I get audio, but I can't
change the volume nor mute it. The debug output from xawtv
and the kernel does give some clues:
,----[ xawtv debug output ]
| cmd: "volume" "mute"
| cmd: "volume" "mute"
| cmd: "volume" "dec"
| cmd: "volume" "dec"
`----
,----[ kernel debug output ]

As you can see, the volume on the mps3400 is unchanged no matter
what I try. Calling "v4lctl volume 0" by hand has the same effect
(ie. none). In this case, setting the volume via tvmixer works
just fine. I tried to convince xawtv to use the tvmixer mixer,
but was unsuccessful.
System details:
Debian GNU/Linux unstable
Kernel 2.2.17 (w/i2c patch)
XFree86 4.0.1d (the CVS version shipped in the experimental .debs)
bttv 0.7.44
xawtv 3.22 (compiled against XFree86 4.0.1)
Hauppauge WinTV-pci with radio, NICAM stereo, and Philips PAL tuner.
I'm using the XFree86 4.0 v4l and Xv extensions, in case it matter for
this problem. It probably doesn't, since fbtv has the same problem
(no control over audio).
This is what the bttv auto-detection code has to say about my card:

`----
I don't think the "msp3410 current mode: ERROR (0x0000)" is the
problem, since this only happens when the tuner is not set to a valid
channel when the driver loads (e.g. on a cold boot).
I hope someone here has a clue 'cause I sure don't...
