I digged a bit deeper into the multiarch issue and as far as I can tell,
the v4l/DVB drivers are missing some compat ioctl handlers which translate
32bit calls into a 64bit system.

It seems this is already being worked on:

64bit kernel.

The call you reported ({t:'o';sz:8}) looks like AUDIO_SET_BYPASS_MODE.
This is being used only in the av7110 driver for the SAA7146 based DVB
cards. But I have no idea where to look for the reason this doesn't work
for you - my knowledge of the kernel-internals is very limited.

This should probably be better asked to the kernel maintainers or on the
linux-media mailinglist.

Sorry, I can't help you with this :-(
