That is, define a new model type, and call stac92xx_set_config_reg() with the check of spec->board_config.This is easy. The problem is that I am already using model "no-jd",
remember?
In this case, if I used
/* was 0x01113014 */ if (spec->board_config > STAC_92HD73XX_NO_JD ) { stac92xx_set_config_reg(codec, 0x0c, 0x01813021); }would be fine to me.
Hm, now the question is why it's wrong. This patch changes the port-C. My concern is whether it's a cabling problem or if it's a BIOS thing. If it's a cabling problem (i.e. the cables don't match with the box), it's not a problem that the driver needs to fix in it. OTOH, if the cabling is OK but just the port-C is mislabeled by BIOS, it's an issue to be fixed as a quirk in the driver.
However, there is a possibility that all "stac92hd73xx" family needs this quirk. In this case, no additional code is needed.
Very unlikely. The pins can be freely assigned, and the port-C is a very basic port. The position, color, association, etc must be different from machine to machine.
Takashi,
Fengguang got the same board I have (DG45ID) and he confirmed that the blue jack was output. The only difference between his computer and mine was that his had an older bios.
This is what he said to me before sending me the patch:
"OK, so it's in fact a general issue. I'll look into it. But I'm afraid I have difficulty in allocating time for it in the near future..."
Therefore, I think we need another quirk.
Thanks.
