For the Twinhan card, data is transferred as Audio DMA, probably 
something goes wrong while doing an audio_reset after initialization, 
and that was most probably the reason Avermedia users were not affected.

I have attached a patch which solves the very same problem in a much 
better way.

Hope Twinhan users can check this out and know whether it works for them
