[ivtv-users] Audio gone?

[Han Hartgers]

Dear all,

I can confirm this "Card: I/O Data GV-MVP/RX" and Ubuntu 9.10
2.6.32-14-generic related problem.

With the by ubuntu provided kernel I have the following error in my log:
[   47.586042] i2c i2c-2: Failed to register i2c client wm8739 at 0x1a (-16)
While the module wm8739 is actually loaded.

[ 4649.226812] wm8739 2-001a: chip found @ 0x34 (ivtv i2c driver #0)

(I had to disable the "firedtv" driver to compile the v4l-dvb version
"/v4l-dvb-2e0444bf93a4")

I will try to make some more recordings to verify if it is really working.
(It was quite a crisis at home with the recorder broken during the
Olympics...)

Greetings,

Han
