Hi!
The attached patch adds initial support of the Mitac 8252D
(http://www.mitac-mtc.com.tw/English/products/8252Dspec.htm).
Working:
- Front speakers (volume + mute)
- Center/LFE speakers (volume + mute)
- HP out (with Front Volume)
- HP individual mute switch
- HP Jack sense
- Front Mic and its volume
Not tested:
- external mic and its volume
Not working while now:
- Mic Jack sense
Questionable:
- is Mic have Jack sense?
- one or two Mic volume controls?
- CD/Line-in: presense in the mixer
