2.6.30: missing audio device in bttv

2.6.30: missing audio device in bttv

[Udo A. Steinberg]

[-- Attachment #1: Type: text/plain, Size: 3387 bytes --]

Hi all,

With Linux 2.6.30 the BTTV driver for my WinTV card claims

	bttv0: audio absent, no audio device found!

and audio does not work. This worked up to and including 2.6.29. Is this a
known issue? Does anyone have a fix or a patch for me to try?

Cheers,

	- Udo

You've no doubt compiled the bttv driver into the kernel and not as a module.

I've just pushed a fix for this to my tree: http://www.linuxtv.org/hg/~hverkuil/v4l-dvb

I've also attached a diff against 2.6.30 since the patch in my tree is against
the newer v4l-dvb repository and doesn't apply cleanly against 2.6.30.

Argh! this is an ugly solution. This can be an workaround for 2.6.30, but the
proper solution is to make sure that i2c core got initialized before any i2c
client.

Jean,

is there any patch meant to fix the usage of i2c when I2C and drivers are compiled with 'Y' ?

No, the i2c core is initialized just fine, but the msp3400 module is later in
the init sequence than bttv. So when bttv initializes and tries to find and
init the msp3400 module it won't find it.

There is something weird going on with either the tveeprom module and/or the
ir-kbd-i2c module. I'm looking into that.

I remember I had to commit a patch moving drivers/media to be compiled after to
i2c core due to a similar problem (git changeset a357482a1e8fdd39f0a58c33ed2ffd0f1becb825).

I suspect that we'll need to work with the initialization order after the new
i2c binding model to avoid such troubles.

I remember that we had a similar issue with alsa and saa7134. At the end, Linus [1]
had to do add this, as a quick hack (unfortunately, it is still there - it
seems that alsa guys forgot about that issue):

late_initcall(saa7134_alsa_init);

On that time, he suggested the usage of subsys_initcall() for alsa. I suspect
that we'll need to do the same for I2C and for V4L core. I'm not sure what
would be the alternative to be done with i2c ancillary drivers.

Maybe one alternative would be to use fs_initcall, that seems to be already
used by some non-fs related calls, like cpu governor [2].

As long as the i2c modules come first there shouldn't be any problem. That's
pretty easy to arrange. So the i2c core inits first, then i2c drivers, then
v4l2 drivers. That's the proper order.

The ir-kbd-i2c module needed to be after the v4l2 modules since that still
relies on autoprobing. If it comes first, then it seems to mess up tveeprom
for some reason. Once ir-kbd-i2c no longer does autoprobing, then it probably
should move back to the other i2c modules.

This is already what we have in 2.6.30 as far as I can see.

Hopefully this will happen in the next few days :)

Hmm, my patch needs a bit more work. But to get your setup working try to
revert the change you made and do just this:

Go to drivers/media/video/Makefile and move this line:

obj-$(CONFIG_VIDEO_MSP3400) += msp3400.o

in front of this line:

obj-$(CONFIG_VIDEO_BT848) += bt8xx/

Recompile and see if that is working.

I got the tveeprom error as well when I tested with ivtv, but I thought that
had something to do with the ivtv driver. Apparently not, so I need to dig a
bit more into these dependencies.

Regards,

Switching those two lines seems to improve the dependencies for my setup.
However, audio still does not work. Furthermore, switching channels in
tvtime now hangs for up to 5 seconds. strace -r shows that it spends a lot
of time in the second ioctl.

0.000085 ioctl(4, VIDIOC_G_TUNER, 0xbfef1d70) = 0
0.000385 select(5, [4], NULL, NULL, {3, 0}) = 1 (in [4], left {2, 988069})
0.012006 ioctl(4, VIDIOC_DQBUF, 0xbfef1dc4) = 0

The current dmesg output is as follows:

Hmm, this looks OK.

I've fixed the problem in my original patch. I've attached the new version.
It works fine with ivtv, the problems with reading the eeprom are now
fixed. Please test and if it still doesn't work then I'll have to install
my bttv card in my PC and test again. But that will be tomorrow evening.

BTW, it would be nice if you can confirm that everything is working fine
if you compile bttv as a module. Just to make sure that this is related
to the in-kernel build. The other person who had this problem (and who
had a very similar card) said that it was working after moving that line
in the Makefile.

Reading the eeprom works with your patch.

That works, too.

Meanwhile I've figured out that the audio problems are related to ALSA. The
BTTV audio signal is fed via a cable to the line-in of my on-board sound.
I've verified that there is audio going over that cable. So I'll talk to the
ALSA folks about the issue.

Thanks for your help, Hans.

Cheers,
