Hi All,
I've also been plagued with the loss of sound in seemingly
random recordings and occasionally when switching
channels on live-tv.

Since I'm in Australia I'm not sure what standard I should
be using. From the ivtv wiki FAQ:

I'm not sure what I should be using. I think Australia
broadcasts PAL-B same as the UK. I know I could
just use trial and error but wondered if someone on
the list had a definitive explanation. Do these values
relate to some other more audio specific set of
standards ?
In the interim I've just been using the following cron
entry which, while quite disgusting, means I only ever
lose a maximum of 60 seconds audio.
* * * * * /root/fixit.sh
The fixit.sh script contains the following:
more /root/fixit.sh
#!/bin/sh
/usr/local/bin/test_ioctl -v input=7,output=1 > /dev/null 2>&1
Where input and output should be changed to match your
requirements.
Again, if anyone has a clear explanation of the msp3400
"standard" parameter... that would be great!
