Please don't drop the cc when replying - I'm passing on my own
experiences with an unrelated card, in the hope that it helps you.
Someone else on the list may look at this and have an "aha!" moment,
answering your question for you.
Note that the increased buffering is important for the SAA7134 - it
seems to only be prepared to transfer audio data in blanking time, so if
there's not enough buffering available, it just drops samples.
