Analog input from HDTV Wonder under Fedora 11

I just upgraded from F10 to F11. Aside from the problems with LIRC (as
mentioned on this list and which I resolved by compiling an LIRC CVS
snapshot), I have one other nagging problem.

My HDTV Wonder supports both digital and analog inputs. I have an analog
input defined so I can get channels my cable company scrambles in digital but
broadcasts in the clear in analog. For the analog input only audio devices of
the form /dev/dspX seem to be supported, but F11 doesn't create this device
when I use my prior modprobe.conf (F10 did).

If I load snd-pcm-oss.ko manually these devices get created (one for my sound
card, one for cx88_alsa for the HDTV Wonder). Does anyone have a suggestion
how this should be done in the "right way"? It would be nice if there were
either a way to specify the ALSA device for the capture card in mythtvsetup.
Alternatively, I would like to do this in a way other than loading the module
in /etc/sysconfig/modules.

TIA!

lirc_serial, correct? 2.6.29.6-211.fc11 or some such thing *should* get
pushed to updates soonish, which carries the fixage.

In semi-related news... lirc_i2c is broken as all hell with 2.6.31 at
the moment...

See /etc/modprobe.d/dist-oss.conf

Actually, lirc_i2c. I think you posted a note elsewhere that there is a buffer
overflow problem that was fixed in CVS.

I guess my (formerly) secret plan to move to mce-usb is well-timed. ;-)

Just noticed that right before I read your reply. I uncommented the line.
Haven't rebooted yet nor tried to see if OSS screws up Pulse. I'll post back
if I hit any snags. Are you aware of any plans to drop OSS from Myth so this
doesn't remain an issue?

BTW: based on the topics of my post, I anticipated you might reply. It brings
me comfort to know that the universe works in the way I hoped. ;-)

Oh, that one. :) Yeah, that's fixed in the same kernel (actually, in an
earlier kernel.

/me curses out-of-tree modules... and self for not getting lirc sent
upstream again yet...

Heh, yes, indeed. I've made some progress on lirc_i2c + 2.6.31, but
still not quite there yet. It compiles, it loads, it sees the right
device type, registers with lirc, etc., but irw isn't reporting seeing
any output at all, and I wind up (mostly) wedging the box when irw exits...

I'd have to say lirc_mceusb and lirc_imon are probably by FAR the most
solid lirc drivers right now.

From what I recall, it doesn't always, but it can. There's a thread
about it somewhere in the fedora-devel-list archives, started by Warren
Togami, iirc (or at least, he was heavily involved in it, as was Lennert
Poettering, the main guy behind pulse).

I know nothing one way or the other, I'm afraid. Of late, making sure
things still compile and run is about as much as I've had time for, have
only very loosely been following the commits list, and have been almost
completely ignoring the devel list. For the most part, my head is
completely buried in kernel code these days, but at least most of what
I'm hack on in my own time is code that benefits MythTV. :)

Yup, hook, line and sinker. I tend to read any email that mentions
Fedora or lirc in its subject much closer than others... Anything else
is hit and miss on whether it sparks enough interest to actually read
it, otherwise, I just can't keep up. :)

...and now I've got it working just fine again. Changes committed to git
tree, will take a bit more doing to shoehorn them into lirc cvs while
still maintaining backwards compatibility... :\ Will do that later, its
past my bed time.
