Asus N75SF turned out to be a pretty cool piece of hardware.
However, subwoofer didn’t work out of the box. So time to open up kate and hack the support for it.
The following patch adds a new model: asus-n75sf, set it as a parameter to intel-hda module and you are good to go.
Or in modprobe.d
options hda-intel model=asus-n75sf
Other features include:
* Automute toggling for headphone plug
* HP jack retasking for mic-in/hp-out/line-out/line-in.
* Subwoofer amp toggling (off in 2 channel mode => saves battery)
* LFE volume regulation
Those retarded ‘genius’ guys from asus decided to wire the internal mic to the jack on the codec that can be configured as line-out, while external mic can only work as a mic.
Sensing of subwoofer presense doesn’t work either. I just couldn’t make sense how it works: it’s not acpi, not codec’s GPIO, not regular pin presense of PIN 0x16.
The draft patch is here. I didn’t yet test line-in, mic-in. SPDIF is muxed with hp-out (see youtube videos). Dond’t have hardware to test. Never used it actually. Obligatory screenshot:
For upmixing K900 made this asoundrc. Lot’s of kudos to him.
The lucky guys using agilia linux will have this patch shipped with the next kernel update.
This patch also works for N55SF, proved by K900.
P.S. You’d better not even boot the preinstalled shit called Win7HP. I couldn’t get my money back for it (Thanks to morons from russian ‘АСК-Сервис’ ). I don’t know if asus has any Q&A, or if this is considered usable. Compared to KDE4 the GUI is damn unresponsive. After I realized I’m not getting my money back for that shit, I booted it and wasted an hour tuning it. Disabling aero, removing tons of bloatware (32-bit in parts on a 64 bit system – way to go!) it didn’t get me any better. Still crappy gui with zero usability for anything more serious than giving skyrim a try.
