From: Hans Verkuil <hans.verk...@cisco.com>
- Instead of using custom ioctls use the VIDIOC_ENUM/G/S/_AUDIO ioctls.
Also send the same audio to both CDROM-out and line-out.
This is what you would expect and anyway, the CDROM-out connector is unlikely
to be used these days as it is obsolete.
- Audio tuner detection was wrong: the tda9840 does not autodetect changes in
the audio standard, so after every change such as changing frequencies that
might affect the audio standard call the tda9840 to attempt to detect it
again.
- Non-PAL standards for composite/S-video inputs were not setup correctly.
- Added querystd support.
