Hi,
working on a new mainboard generation with ALC671 codecs the first tests
showed that the generic codec parser is just configuring the rear mic in
for audio input, line-in and front-mic are missing.
I tried to understand the code of patch_realtek.c and after compiling
with CONFIG_SND_DEBUG I saw that this module is not used at all for the
ALC671 codec because its device-ID was missing.
So what I did is:
- adding the device id and assigned the ALC662 patches for it.
- Added the device id so that it enables 4 ports in
alc662_parse_auto_config
- changed the conditional in alc_subsystem_id because it looked so
strange to me when I tried to understand what is happening. :-)
Here is the patch:
