Re: Sound level problem after installing 2nd tuner card
[In reply to]
|

To my knowledge there's not currently any way to sync the audio levels
across multiple capture cards. This has been discussed quite a bit on the
lists and it's a known issue, but I don't think there's a fix as of yet.
There was some discussion of adding a per-card audio level setting, but I'm
not sure if anyone ever started implementing that. Unfortunately, I can't
be of any help with your other questions. Hopefully someone else will chime
in with some more knowledge in those areas.
