Yes. The values in the array controlling the MUX doesn't work for
all cards. To get sound from my card I had to switch the values
for selecting tuner and mute.
I think we need to add a separate MUX array for each cardtype (at least
for the Hauppauge ones). No, I don't mind doing it, if I get some data to
work with.

My card has this stereo chip too (it's actually a MSP3410D), and I've
never had any problems. But maybe my version has better power-on
defaults ?

I once talked to a nice freindly technician at H. (he even faxed me a
couple of pages from a datasheet, that I couldn't get from Philips).
I asked him if he could send me any documantation on the format of their
eeprom. He replied that the "powers that be" in H. had decided that the
format of the eeprom was proprietary(sp?). The reason was supposed to be
that they'd like to be able to change the format. He hinted that the
Linux people had started a decoding project.
