[alsa-devel] ALC883 features
Hi,
I'm new here.
I just bought a new computer from Dell with a Realtek ALC1200 (883?). After messing with alsa configurations and looking into the driver code a bit, I noted that a few features i'd like don't seem to be supported by the current driver.
1) Use of all 10 channels, only 8 are wired out to the 7.1 pcm device (forgive me if i lack the proper terminology for the moment). From the 883 datasheet, and comments in 1.0.20 code it seems the last 2 channels could be wired out as a separate PCM device.
2) Some more controls, specifically the ability to prevent the headphone jack from automuting the speakers. And if its possible to wire out the missing two channels then perhaps some more controls for the new channels.
I was wondering if there someone who might point me in the right direction to get started with fixing up these things in the driver.
Are my ambitions realistic, or am I barking up the tree of having to rewrite the whole HDA driver?
Thanks, Michael

How did you conclude that the ALC883 specs apply to the ALC1200? Every source I can find says the ALC1200 is an 8 channel codec. Unfortunately there's no Realtek doc for the ALC1200 so this is based on various reviews and forum posts...
