[mpeg2] Solution for missing audio with BMK MPEX w/ tuner

[Johann Hanne <jhml@gmx.net>]

Hi,

I've had problems with the BMK MPEX board with tuner: There was no audio when 
using the tuner, neither with xawtv/fbtv nor in the MPEG2-TS from 
/dev/video1. After some hours I've found out that the saa7134 driver was 
using the wrong audio line. The attached patch "fixes" this.

The strange thing is that the original patch which introduced support for the 
MPEX board with tuner already had this right. So i wonder who changed it, 
maybe there are different hardware revisions using different lines? Everybody 
who has the board running fine without this patch might want to note it on 
this list...

Apart from this little problem the card is running fine with kernel 2.4.23 and 
the latest patchset from http://bytesex.org (2.4.23-3), just don't forget to 
supply the "card=23" parameter when modprobing the saa7134 module.

Cheers, Jonny
